[jira] Commented: (CASSANDRA-1380) Create a statistics keyspace

["Kelley Reynolds (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12897452#action_12897452 ] 

Kelley Reynolds commented on CASSANDRA-1380:
--------------------------------------------

If your entire cluster is dead then yes, you won't be able to access the data inside of it but that's only one extreme case under which it's not useful. Trended statistics are attractive for much more than just monitoring. You could see impending I/O bottlenecks, RF>1 clusters would let you examine behavior just before a crash, facilitate debugging and recommendations, and myriad other things that other people can think of. Many other systems have stats collectors built-in that are used to augment existing monitoring systems and troubleshoot/optimize application behavior, I can't think of a reason Cassandra should be any different.

> Most significant installations of cassandra have monitoring systems that monitor and trend several key tpstats among other things. Instead of replicating that for each and every installation, it would be useful to have that provided by the core system in a default keyspace. Comprehensive statistics would allow for improved debugging tools, performance recommendations, helpful alerts, introspection, that sort of thing.
