----------------------------------------
Summary: Create ignite troubleshooting logger
Key: IGNITE-5473
URL: https://issues.apache.org/jira/browse/IGNITE-5473
Project: Ignite
Issue Type: Improvement
Components: general
Affects Versions: 2.0
Reporter: Alexey Goncharuk
Priority: Critical
Fix For: 2.2
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
(add more)
