Role Triggers

Description

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.

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",
