SLA for Workflow Parameters

You can set Service Level Agreement (SLA) parameters within most action node configurations or you can set them from the Settings menu so they are applied to all workflows. Settings in the action node dialog box override the global settings.

Enabling SLA results in alerts being generated whenever an SLA time is missed. You can also have alerts sent as email notifications. SLA settings do not impact whether or not a job runs or completes. If a job misses SLA and you want the job to stop, you must manually stop the job.

If SLA is defined for a workflow action that is not in the execution path because of a decision node, you get an SLA_MISS notification.

For more information, see Apache Oozie SLA Monitoring.
