Alexey Goncharuk updated IGNITE-5473:
-------------------------------------
Description:
Currently, we have two extremes of logging - either INFO wich logs almost
nothing, or DEBUG, which will pollute logs with too verbose messages.
We should create a 'troubleshooting' logger, which should be easily enabled
(via a system property, for example) and log all stability-critical node and
cluster events:
* Connection events (both communication and discovery), handshake status
* ALL ignored messages and skipped actions (even those we assume are safe to
ignore)
* Partition exchange stages and timings
* Verbose discovery state changes (this should make it easy to understand the
reason for 'Node has not been connected to the topology')
* Transaction failover stages and actions
* All unlogged exceptions
* Responses that took more than N milliseconds when in normal they should
return right away
(add more)
The amount of logging should be chosen accurately so that it would be safe to
enable this logger in production clusters.
