T Jake Luciani commented on CASSANDRA-7838:
-------------------------------------------

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

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.
