[jira] [Created] (MESOS-5376) Add systemd watchdog support

David Robinson created MESOS-5376:
-------------------------------------

             Summary: Add systemd watchdog support
                 Key: MESOS-5376
                 URL: https://issues.apache.org/jira/browse/MESOS-5376
             Project: Mesos
          Issue Type: Improvement
            Reporter: David Robinson


It would be great if Mesos had support for systemd's [watchdog|http://0pointer.de/blog/projects/watchdog.html]. Users would typically use a supervisor like [monit|https://mmonit.com/monit/] to check the agent/master's /health endpoint and restart upon consecutive failures. Systemd doesn't support polling services, it uses a watchdog to communicate liveliness instead. Supervisor solutions like monit could be replaced with systemd if mesos had watchdog support. Note that simply restarting the service upon failure (ie, when the process exits) is not sufficient -- a deadlock within mesos would not cause the process to exit but a watchdog could detect this.
