Subject [jira] [Updated] (IGNITE-6587) Ignite watchdog service
Date Wed, 15 Nov 2017 12:18:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-6587?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Puchnin updated IGNITE-6587:
-----------------------------------
    Description: 
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.

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:
All TCP discovery threads
All communication NIO threads (acceptor and workers)
Exchange worker
Striped pool threads
Timeout Worker
Checkpointer 
WAL archiver

The mechanism should support pluggable components so that self-check can be extended via plugins.
