Subject [jira] [Commented] (CASSANDRA-8093) Add Metrics for OS and hardware usage with Sigar
Date Mon, 25 Jan 2016 16:07:39 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8093?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15115451#comment-15115451

T Jake Luciani commented on CASSANDRA-8093:
-------------------------------------------

Yeah, over a year later I'm not sure this makes sense vs getting these from collectd.

If there are specific metrics that we can add which help C* operators and require OS metrics
as part of the calculation then we should consider those.
One Idea might be to track other processes which may be running on the box causing load. 
Also tracking the process size according to the OS which includes all the off heap stuff.

> Now that CASSANDRA-7838 is in we can expose many OS and hardware specific metrics which
will be useful for operators who want a holistic view of their nodes from Cassandra.
