Subject [jira] [Commented] (CASSANDRA-7838) Warn user when OS settings are poor / integrate sigar
Date Thu, 09 Oct 2014 01:00:36 GMT


T Jake Luciani commented on CASSANDRA-7838:

Looks good thanks Josh.  I just want to check the debian package and tarball look good before

bq. Once this gets patched in I am interested to see if there is interest in capturing SIGAR
metrics periodically.

Yes that is my intention, to capture all kinds of metrics periodically from the system. I'll
open a new ticket and we can start listing some.

that will make them sad, like Network drive or EBS on Ec2.
