Joseph Lynch commented on CASSANDRA-14553:
------------------------------------------
Working on it over in a [github
branch|https://github.com/jolynch/cassandra/tree/jolynch_write_troubleshooting]
> Document troubleshooting page
> -----------------------------
>
> Key: CASSANDRA-14553
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14553
> Project: Cassandra
> Issue Type: Improvement
> Components: Documentation and Website
> Reporter: Joseph Lynch
> Priority: Minor
> Labels: Documentation
>
> Currently the [troubleshooting
> docs|http://cassandra.apache.org/doc/latest/troubleshooting/] are blank. As
> much as I like to believe Cassandra never has any problems I was thinking of
> writing up a troubleshooting page focussing on:
> # Finding the hosts(s) that are behaving badly (common error messages)
> # Which logs exist, where they are, and what to look for in which log
> (common error messages, gc logs, etc)
> # Which nodetool commands can give you more information
> # Java/Operating systems tools that can help dive deep into performance
> issues (jstat, top, iostat, cachestat, etc)
> Since this is going to be a fairly lengthy page I wanted to get a jira going
> in case someone else had ideas or had already started. Also if there are any
> large areas I missed above please comment here and I can include them.
