Andrey Kuznetsov updated IGNITE-6587:
-------------------------------------
Description:
As described in [1], each Ignite node has a number of system-critical threads.
We should implement a periodic check that calls failure handler when one of the
following conditions has been detected:
# Critical thread is not alive anymore.
# Critical thread remains in BLOCKED state for a long time.
Actual list of system-critical threads can be found at [1].

was:
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.
