Lawrence Wu commented on MESOS-5376:
------------------------------------
The basic, high-level plan is:
- check that the WATCHDOG_USEC environment variable is set
- if it is set, spin off a thread and hit the watchdog service every half of
WATCHDOG_USEC interval
I'll start digging into the code now.
> Add systemd watchdog support

> 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.
