> Watchdog is watching for ChukwaAgent only once every 5 minutes, so there's no point in
retrying more than once every 5 mins.
> In practice, if the watchdog is not able to automatically restart the agent, it will
take more than 20 minutes to get Ops to restart it.
> Also Ops want us to limit the number of communications between Hadoop and Chukwa, that's
why 30 minutes.
