Role Triggers	The configured triggers for this role. This is a JSON formatted list of triggers. These triggers are evaluated as part as the health system.

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 will not be evaluated. For example, here is a JSON formatted trigger configured for a DataNode that 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"}]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.

Each trigger has all of 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 will not be evaluated. For example, here is a JSON formatted trigger configured for a DataNode that 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"}]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.
