> We need to come up with a 'watchdog service' to monitor for Ignite node local health and kill the process under some critical conditions.
> For example, if one of the mission-critical Ignite threads die, the Ignite node must be stopped.
> At the first glance, the list of critical threads is:
> disco-event-worker
> tcp-disco-sock-reader
> tcp-disco-srvr
> tcp-disco-msg-worker
> tcp-comm-worker
> grid-nio-worker-tcp-comm
> exchange-worker
> sys-stripe
> grid-timeout-worker
> db-checkpoint-thread
> wal-file-archiver
> ttl-cleanup-worker
> nio-acceptor
> The mechanism should support pluggable components so that self-check can be extended via plugins.
