Bug ID: 54787
Summary: monitor gallium disk performances
Product: Wikimedia

OS: All
Status: NEW
Severity: normal
Priority: Unprioritized

Ever since gallium got upgraded from Lucid to Precise, we have been suffering
disk I/O latency. If my memory serves me well, the MediaWiki dump tests went
from 30 seconds to 1 minutes.
From time to time, we get massive latency on gallium slave. It would be nice to
have the disk statistics monitored in Ganglia.
That should be possible with ganglia::diskstat introduced by
https://gerrit.wikimedia.org/r/#/c/85669/ for bug 36994
This bug is merely a remember to get the diskstat ganglia plugin applied in
gallium (and lanthanum).
