| 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 all of 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 will not be evaluated.
For example, here is a JSON formatted trigger that 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"}]Consult the trigger rules documentation
for more details on how to write triggers using tsquery.The JSON format is evolving and may change in the future and as a result backward compatibility is not guaranteed between releases at this
time. |
