Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Use .* instead , alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false
Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false
Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Custom Alert Script If configured, this script is invoked on the machine hosting the alert publisher role. The script must be readable and executable by the cloudera-scm user. The script is passed, as a single argument, a path to a UTF-8 JSON file containing a list of alerts. Alerts are, by default, batched over time, and the batch size and the batch interval are configurable with the "Alert Publisher: Maximum Batch Size" and "Alert Publisher: Maximum Batch Interval" configuration options. The alerts file is deleted when the script finishes executing. Only one instance of this script is invoked at any given time, and the script must terminate.

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false
Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Alert On Transitions Out of Alerting Health If set, the health events for transitions out of an alertable health level will also be considered an alert. For example, consider an entity that is configured to alert when it has bad health. If that entity's health becomes bad, an alert will be generated. If this setting is enabled, an alert will also be generated when it returns to good health. If this setting is disabled, then no alert will be generated when it returns to good health. Note that an entity must have enable_alerts set to true for health alerts to be generated for it. And make sure to reference the per-entity setting to turn on health alerts. false eventserver_alert_on_transition_out_of_alerting_health_enabled false

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Use .* instead , alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false

Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Host Monitor Storage Directory The directory where Host Monitor data is stored. The Host Monitor stores metric time series and health information. firehose.storage.base.directory /var/lib/cloudera-host-monitor firehose_storage_dir true
Time-Series Storage The approximate amount of disk space dedicated to storing time series and health data. Once the store has reached its maximum size, older data is deleted to make room for newer data. The disk usage is approximate because data is deleted only when the limit is reached.Note that Cloudera Manager stores time-series data at a number of different data granularities, and these granularities have different effective retention periods. Specifically, Cloudera Manager stores metric data as both raw data points and ten-minutely, hourly, six-hourly, daily, and weekly summary data points. Raw data consumes the bulk of the allocated storage space, weekly summaries the least. As such, raw data is retained for the shortest amount of time, while weekly summary points are unlikely to ever be deleted.See the "Storage" tab on the 'Host Monitor' -> 'Charts Library' -> 'Host Monitor Storgae' page for more information on how space is consumed within the Host Monitor.

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Use .* instead , alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false

Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Enable Audit Collection Enable collection of audit events from the service's roles. navigator.audit.enabled true navigator_audit_enabled false
Audit Event Filter Event filters are defined in a JSON object like the following: { "defaultAction" : ("accept", "discard"), "rules" : [ { "action" : ("accept", "discard"), "fields" : [ { "name" : "fieldName", "match" : "regex" } ] } ] } A filter has a default action and a list of rules, in order of precedence. Each rule defines an action, and a list of fields to match against the audit event. A rule is "accepted" if all the listed field entries match the audit event. At that point, the action declared by the rule is taken. If no rules match the event, the default action is taken. Actions default to "accept" if not defined in the JSON object. The following is the list of fields that can be filtered for NAVMS events:
  • operation: Navigator operation performed e.g. auditReport, savedSearch etc.
  • username: the user performing the action.
  • ipAddress: the IP from where the request originated.
  • allowed: whether the operation was allowed or denied.

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Use .* instead , alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false

Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Extra Space Ratio for Indexing Reports Manager uses an array to store HDFS directory tree during indexing. The size of this array is 3 * number of filesystem objects in HDFS * (1 + extra space ratio). Increasing this ratio allows Reports Manager to create the directory tree faster, but consumes more memory. Also, extra space ratio must be set to a small enough value so that size of the array is below the maximum allowed in Java, which is 2^31 - 1. index.space.extra.ratio 0.2 headlamp_index_space_extra_ratio false

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.

Warning: Never, Critical: Never reportsmanager_scratch_directory_free_space_percentage_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated.

Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Time-Series Storage The approximate amount of disk space dedicated to storing time series and health data. Once the store has reached its maximum size, older data is deleted to make room for newer data. The disk usage is approximate because data is deleted only when the limit is reached.Note that Cloudera Manager stores time-series data at a number of different data granularities, and these granularities have different effective retention periods. Specifically, Cloudera Manager stores metric data as both raw data points and ten-minutely, hourly, six-hourly, daily, and weekly summary data points. Raw data consumes the bulk of the allocated storage space, weekly summaries the least. As such, raw data is retained for the shortest amount of time, while weekly summary points are unlikely to ever be deleted.See the "Storage" tab on the 'Service Monitor' -> 'Charts Library' -> 'Service Monitor Storgae' page for more information on how space is consumed within the Service Monitor.

Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' memory.soft_limit_in_bytes -1 MiB rm_memory_soft_limit true

Service Triggers The configured triggers for this service. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific service.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the followig JSON formatted trigger fires if there are more than 10 DataNodes with more than 500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleType = DataNode and last(fd_open) > 500) DO health:bad", "streamThreshold": 10, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Rules to Extract Events from Log Files This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
  • alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".
  • rate (mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.
  • periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute
  • threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.
  • content - match only those messages for which contents match this regular expression.
  • exceptiontype - match only those messages that are part of an exception message. The exception type must match this regular expression.
Example:
  • {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.
  • {"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
 version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Use .* instead , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false
Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.
