Rules to Extract Events from Log Files

Description

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.

Default Value

version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 0, threshold: WARN, content: .* is deprecated.

Metric Filter

Description

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:

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

Description

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.

Rules to Extract Events from Log Files

Description

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.

Service Triggers

Description

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",
