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
Navigator Audit Failure Thresholds The health test thresholds for failures encountered when monitoring audits within a recent period specified by the mgmt_navigator_failure_window configuration for the role. The value that can be specified for this threshold is the number of bytes of audits data that is left to be sent to audit server. mgmt.navigator.failure.thresholds Warning: Never, Critical: Any mgmt_navigator_failure_thresholds false
Monitoring Period For Audit Failures The period to review when checking if audits are blocked and not getting processed. mgmt.navigator.failure.window 20 minute(s) mgmt_navigator_failure_window false
Navigator Audit Pipeline Health Check Enable test of audit events processing pipeline. This will test if audit events are not getting processed by Audit Server for a role that generates audit. mgmt.navigator.status.check.enabled true mgmt_navigator_status_check_enabled false
Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. Enter the metric names to be included or excluded using the Metric Name parameter.
  • Metric Name - The name of a metric that will be included or excluded during metric collection.
If you do not select Health Test Metric Set or Default Dashboard Metric Set, or specify metrics by name, metric filtering will be turned off (this is the default behavior).For example, the following configuration enables the collection of metrics required for Health Tests and the jvm_heap_used_mb metric:
  • Include only Health Test Metric Set: Selected.
  • Include/Exclude Custom Metrics: Set to Include.
  • Metric Name: jvm_heap_used_mb
You can also view the JSON representation for this parameter by clicking View as JSON. In this example, the JSON looks like this:{ "includeHealthTestMetricSet": true, "filterType": "whitelist", "metrics": ["jvm_heap_used_mb"] }
monitoring_metric_filter 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.
[] role_triggers true
Unexpected Exits Thresholds The health test thresholds for unexpected exits encountered within a recent period specified by the unexpected_exits_window configuration for the role. Warning: Never, Critical: Any unexpected_exits_thresholds false
Unexpected Exits Monitoring Period The period to review when computing unexpected exits. 5 minute(s) unexpected_exits_window 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: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 1, periodminutes: 2, exceptiontype: .* , alert: false, rate: 1, periodminutes: 1, threshold: WARN ] log_event_whitelist false
Navigator Audit Failure Thresholds The health test thresholds for failures encountered when monitoring audits within a recent period specified by the mgmt_navigator_failure_window configuration for the role. The value that can be specified for this threshold is the number of bytes of audits data that is left to be sent to audit server. mgmt.navigator.failure.thresholds Warning: Never, Critical: Any mgmt_navigator_failure_thresholds false

Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. Enter the metric names to be included or excluded using the Metric Name parameter.
  • Metric Name - The name of a metric that will be included or excluded during metric collection.
If you do not select Health Test Metric Set or Default Dashboard Metric Set, or specify metrics by name, metric filtering will be turned off (this is the default behavior).For example, the following configuration enables the collection of metrics required for Health Tests and the jvm_heap_used_mb metric:
  • Include only Health Test Metric Set: Selected.
  • Include/Exclude Custom Metrics: Set to Include.
  • Metric Name: jvm_heap_used_mb
You can also view the JSON representation for this parameter by clicking View as JSON. In this example, the JSON looks like this:{ "includeHealthTestMetricSet": true, "filterType": "whitelist", "metrics": ["jvm_heap_used_mb"] }
monitoring_metric_filter 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.

Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. Enter the metric names to be included or excluded using the Metric Name parameter.
  • Metric Name - The name of a metric that will be included or excluded during metric collection.
If you do not select Health Test Metric Set or Default Dashboard Metric Set, or specify metrics by name, metric filtering will be turned off (this is the default behavior).For example, the following configuration enables the collection of metrics required for Health Tests and the jvm_heap_used_mb metric:
  • Include only Health Test Metric Set: Selected.
  • Include/Exclude Custom Metrics: Set to Include.
  • Metric Name: jvm_heap_used_mb
You can also view the JSON representation for this parameter by clicking View as JSON. In this example, the JSON looks like this:{ "includeHealthTestMetricSet": true, "filterType": "whitelist", "metrics": ["jvm_heap_used_mb"] }

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.

Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. Enter the metric names to be included or excluded using the Metric Name parameter.
  • Metric Name - The name of a metric that will be included or excluded during metric collection.
If you do not select Health Test Metric Set or Default Dashboard Metric Set, or specify metrics by name, metric filtering will be turned off (this is the default behavior).For example, the following configuration enables the collection of metrics required for Health Tests and the jvm_heap_used_mb metric:
  • Include only Health Test Metric Set: Selected.
  • Include/Exclude Custom Metrics: Set to Include.
  • Metric Name: jvm_heap_used_mb

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.

HBase Hash Type The hashing algorithm for use in HashFunction. Two values are supported: 'murmur' (for MurmurHash) and 'jenkins' (for JenkinsHash). hbase.hash.type murmur hbase_hash_type false
HBase HRegion Major Compaction The time, in milliseconds, between 'major' compactions of all HStoreFiles in a region. To disable automated major compactions, set this value to 0. hbase.hregion.majorcompaction 7 day(s) hbase_hregion_majorcompaction false
HBase HRegion Major Compaction Jitter Jitter outer bound for major compactions.
 On each RegionServer, the hbase.region.majorcompaction
 interval is multiplied by a random fraction that is inside the bounds of this
 maximum. This + or - product is added to when the next
 major compaction is to run. Major compaction
 should not occur on every RegionServer at the same time. The
 smaller this number, the closer together the compactions. hbase.hregion.majorcompaction.jitter 0.5 hbase_hregion_majorcompaction_jitter false
HBase Maximum File Size Maximum HStoreFile size. If any one of a column families' HStoreFiles has grown to exceed this value, the hosting HRegion is split in two. hbase.hregion.max.filesize 10 GiB hbase_hregion_max_filesize false
HBase Memstore Block Multiplier Blocks writes if the size of the memstore increases to the value of 'hbase.hregion.block.memstore' multiplied by the value of 'hbase.hregion.flush.size' bytes. This setting is useful for preventing runaway memstore during spikes in update traffic. Without an upper-bound, memstore fills such that when it flushes, the resultant process of flushing files take a long time to compact or split, or worse, an "out of memory" error occurs. hbase.hregion.memstore.block.multiplier 2 hbase_hregion_memstore_block_multiplier false
HBase Memstore Flush Size Memstore will be flushed to disk if size of the memstore exceeds this value in number of bytes.

Maximum Byte Array from MSLAB Allocation Scheme The maximum size byte array that should come from the MSLAB, in bytes. hbase.hregion.memstore.mslab.max.allocation 256 KiB hbase_hregion_memstore_mslab_max_allocation false
HBase Memstore Pre-close Flush Size If the memstores in a region are this size or larger when closing, run a pre-flush process to clear out memstores before putting up the region closed flag and taking the region offline. On close, a flush process is run under the close flag up to empty memory. During this time, the region is offline and no writes are taken. If the memstore content is large, the flush process could take a long time to complete. The pre-flush process cleans out the bulk of the memstore before putting up the close flag and taking the region offline, so that the flush process that runs under the close flag has little to do. hbase.hregion.preclose.flush.size 5 MiB hbase_hregion_preclose_flush_size false
HStore Blocking Store Files If there are more than this number of HStoreFiles in any one HStore, then updates are blocked for this HRegion until a compaction is completed, or until the value specified for 'hbase.hstore.blockingWaitTime' has been exceeded. hbase.hstore.blockingStoreFiles 16 hbase_hstore_blockingStoreFiles false
HStore Blocking Wait Time The period of time that an HRegion will block updates after reaching the HStoreFile limit that is specified by 'hbase.hstore.blockingStoreFiles'. After this time has elapsed, the HRegion will stop blocking updates even if a compaction has not been completed. hbase.hstore.blockingWaitTime 1 minute(s), 30 second(s) hbase_hstore_blockingWaitTime false
Maximum Number of HStoreFiles Compaction Maximum number of HStoreFiles to compact per minor compaction. hbase.hstore.compaction.max hbase_hstore_compaction_max false
HStore Compaction Threshold If this number of HStoreFiles in any one HStore is exceeded, then a compaction is run to rewrite all HStoreFiles files as one HStoreFile. (One HStoreFile is written per flush of memstore.) You can delay compaction by specifying a larger number, but the compaction will take longer when it does run. During a compaction, updates cannot be flushed to disk. Long compactions require memory sufficient to carry the logging of all updates across the duration of the compaction. If too large, clients timeout during compaction. hbase.hstore.compactionThreshold 3 hbase_hstore_compactionThreshold false
Enable Replication To Secondary Region Replicas Whether asynchronous WAL replication to the secondary region replicas is enabled.
 If enabled, a replication peer named 'region_replica_replication' is created
 that tails the logs and replicates the mutations to region replicas for tables that
 have region replication > 1. Disabling this replication also
 requires disabling the replication peer using shell or the ReplicationAdmin Java class.
 Replication to secondary region replicas works over standard intercluster replication. If disabled explicitly, enable replication by setting 'hbase.replication' to true for this feature to work.

Low Watermark for Memstore Flush Controls when memstores are forced to flush to make room in memory. The memstore will begin flushing when this threshold is reached. Prior to CDH 5.8.0, this amount is the percentage of the heap size of the Region Server and you can set it equal to 'Maximum Size of All Memstores in RegionServer' for minimal possible flushing. In CDH 5.8.0 and later, this amount is the percentage of memstore memory and you can set it equal to 1.0 for minimal possible flushing. hbase.regionserver.global.memstore.size.lower.limit 0.95 hbase_regionserver_global_memstore_lowerLimit false

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 HBase events:
  • allowed: whether the operation was allowed or denied.
  • username: the user performing the action.
  • tableName: the table affected by the operation.
  • family: the column family affected by the operation.
  • qualifier: the qualifier the operation.
  • action: the action being performed.
The default HBase audit event filter discards events that affect the internal -ROOT-, .META. and _acl_ tables.
navigator.event.filter comment: [ The default HBase audit event filter discards events that affect the , internal -ROOT-, .META. and _acl_ tables. ], defaultAction: accept, rules: [ action: discard, fields: [ name: tableName, match: (?:-ROOT-|.META.|_acl_|hbase:meta|hbase:acl) ] ] navigator_audit_event_filter false
Audit Queue Policy Action to take when the audit event queue is full. Drop the event or shutdown the affected process. navigator.batch.queue_policy DROP navigator_audit_queue_policy false
Audit Event Tracker Configures the rules for event tracking and coalescing. This feature is used to define equivalency between different audit events. When events match, according to a set of configurable parameters, only one entry in the audit list is generated for all the matching events. Tracking works by keeping a reference to events when they first appear, and comparing other incoming events against the "tracked" events according to the rules defined here. Event trackers are defined in a JSON object like the following: { "timeToLive" : [integer], "fields" : [ { "type" : [string], "name" : [string] } ] } Where:
  • timeToLive: maximum amount of time an event will be tracked, in milliseconds. Must be provided. This defines how long, since it's first seen, an event will be tracked. A value of 0 disables tracking.
  • fields: list of fields to compare when matching events against tracked events.
Each field has an evaluator type associated with it. The evaluator defines how the field data is to be compared. The following evaluators are available:
  • value: uses the field value for comparison.
  • username: treats the field value as a user name, and ignores any host-specific data. This is useful for environment using Kerberos, so that only the principal name and realm are compared.
The following is the list of fields that can used to compare HBase events:
  • operation: the HBase operation being performed.
  • username: the user performing the action.
  • ipAddress: the IP from where the request originated.
  • allowed: whether the operation was allowed or denied.
  • tableName: the name of the table affected by the operation.
  • family: the column family affected by the operation.
  • qualifier: the qualifier of the operation.
The default event tracker for HBase services defines equality by comparing the username, operation, table name, family, and qualifier of the events.
navigator_event_tracker comment: [ The default event tracker for HBase services defines equality by , comparing the username, operation, table name, family, and qualifier of , the events. ], timeToLive: 60000, fields: [ type: value, name: tableName , type: value, name: family , type: value, name: qualifier , type: value, name: operation , type: username, name: username ] navigator_event_tracker false

Log Event Retry Frequency The frequency in which the log4j event publication appender will retry sending undelivered log events to the Event server, in seconds 30 log_event_retry_frequency false
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 following 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.

If a relative path is given, the parent folder will be ${zookeeper.znode.parent}. By default, the root location is stored at /hbase/root-region-server. zookeeper.znode.rootserver root-region-server zookeeper_znode_rootserver true

Performance

Display Name Description Related Name Default Value API Name Required
Enable HDFS Short-Circuit Read Enable HDFS short-circuit read. This allows a client colocated with the DataNode to read HDFS file blocks directly. This gives a performance boost to distributed clients that are aware of locality. dfs.client.read.shortcircuit true dfs_client_read_shortcircuit false
HDFS Hedged Read Threadpool Size Size of the threadpool used for hedged reads in hdfs clients. If a read from a block is slow, a parallel 'hedged' read will be started against a different block replica. The first one to return with a result is used while the other one is cancelled. This 'hedged' read feature helps rein in the outliers. A value of zero disables the feature. dfs.client.hedged.read.threadpool.size 0 hbase_server_dfs_client_hedged_read_threadpool_size false
HDFS Hedged Read Delay Threshold Duration to wait before starting up a 'hedged' read. dfs.client.hedged.read.threshold.millis 500 millisecond(s) hbase_server_dfs_client_hedged_read_threshold_millis false
