Subject [jira] [Commented] (CASSANDRA-10241) Keep a separate production debug log for troubleshooting
Date Thu, 10 Sep 2015 12:28:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14738661#comment-14738661
] 

Paulo Motta commented on CASSANDRA-10241:
-----------------------------------------

Updated 2.2+ branch creating debug.log with async appender, and enabling {{DEBUG}} log on
aforementioned packages by default. Cassci test links remain the same.

I played around with one node, and the verbosity of debug.log seems acceptable, except for
{{org.apache.cassandra.service.GCInspector}} which was logging too much of these messages:
{noformat}
DEBUG [Service Thread] 2015-09-10 09:07:36,882 ?:? - ParNew GC in 3ms.  CMS Old Gen: 232350496
-> 232350712; Par Eden Space: 41943040 -> 0; Par Survivor Space: 22784 -> 20800
DEBUG [Service Thread] 2015-09-10 09:07:37,026 ?:? - ParNew GC in 4ms.  CMS Old Gen: 232350712
-> 232350840; Par Eden Space: 41943040 -> 0; Par Survivor Space: 20800 -> 22704
DEBUG [Service Thread] 2015-09-10 09:07:37,169 ?:? - ParNew GC in 4ms.  CMS Old Gen: 232350840
-> 232350960; Par Eden Space: 41943040 -> 0; Par Survivor Space: 22704 -> 14528
DEBUG [Service Thread] 2015-09-10 09:07:37,318 ?:? - ParNew GC in 4ms.  CMS Old Gen: 232350960
-> 232351024; Par Eden Space: 41943040 -> 0; Par Survivor Space: 14528 -> 18480
{noformat}

So, took the chance to update {{GCInspector}} and reduce the level of these logs to {{TRACE}}.

> [~aweisberg] had the suggestion to keep a separate debug log for aid in troubleshooting,
not intended for regular human consumption but where we can log things that might help if
something goes wrong.
