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",
  "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.

Log and Query Redaction Policy

Description: Note: Do not edit this property in the classic layout. Switch to the new layout to use preconfigured redaction rules and test your rules inline.Use this property to define a list of rules to be followed for redacting sensitive information from log files and query strings. Click + to add a new redaction rule. You can choose one of the preconfigured rules or add a custom rule. When specifying a custom rule, the Search field should contain a regular expression that will be matched against the data. If a match is found, it is replaced by the contents of the Replace field.Trigger is an optional field. It can be used to specify a simple string to be searched in the data. If the string is found, the redactor attempts to find a match for the Search regex. If no trigger is specified, redaction occurs by matching the Search regular expression. Use the Trigger field to enhance performance: simple string matching is faster than regular expression matching.Test your rules by entering sample text into the Test Redaction Rules text box and clicking Test Redaction. If no rules match, the text you entered is returned unchanged.
