[jira] [Updated] (CASSANDRA-13460) Diag. Events: Add local persistency

["Stefan Podkowinski (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-13460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stefan Podkowinski updated CASSANDRA-13460:
-------------------------------------------
    Status: Patch Available  (was: In Progress)

Persisting critical events will be enabled by default and hopefully will enable users to provide additional debugging information along with logs or stacktraces in their bug reports. Please see the [documentation|https://github.com/spodkowinski/cassandra/blob/WIP-13460/doc/source/operating/diag_events.rst] for an introduction.

The proposed implementation will take care of:
* Creation of system table for storing events
* Allowing to configure certain events to be persisted to system table (enabled for some events by default)
* Documentation on configuration and querying of events

> Some generated events will be rather less frequent but very useful for retroactive troubleshooting. E.g. all events related to bootstraping and gossip would probably be worth saving, as they might provide valuable insights and will consume very little resources in low quantities. Imaging if we could e.g. in case of CASSANDRA-13348 just ask the user to run a tool like {{./bin/diagdump BootstrapEvent}} on each host, to get us a detailed log of all relevant events. 
> This could be done by saving events white-listed in cassandra.yaml to a local table. Maybe using a TTL.
