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.
[{"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. - Related Name
