Dataflow - Check for Hanged Jobs¶

Once started, a job in the Cloud Dataflow service transits from state to state and normally enters a terminal state. Custodian can check if there are any jobs hanging in temporary statuses abnormally long.

Note that the notify action requires a Pub/Sub topic to be configured. To configure Cloud Pub/Sub messaging please take a look at the Generic Actions page.

In the example below, the policy checks if there are any jobs which started over 1 day ago (configurable period) but not yet transitioned to a certain stable state for some reason (remains in JOB_STATE_RUNNING, JOB_STATE_DRAINING, JOB_STATE_CANCELLING statuses) and therefore may need administrator’s attention.
