Subject [jira] [Created] (AIRFLOW-349) Metric for zombies killed
Date Wed, 20 Jul 2016 18:06:21 GMT
Dan Davydov created AIRFLOW-349:
-----------------------------------

             Summary: Metric for zombies killed
                 Key: AIRFLOW-349
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-349
             Project: Apache Airflow
          Issue Type: Improvement
          Components: operators
            Reporter: Dan Davydov
            Assignee: Dan Davydov
            Priority: Minor


There should be a metric exported every time a zombie (job that can't heartbeat the scheduler)
is killed, as if the number of zombies killed spikes it will cause delayed tasks/spurious
failure emails/multiple copies of a taskinstance running at the same time.
