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 all of the following fields:

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\",\n  \"triggerExpression\": \"IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad\",\n  \"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.
