Ceph Device metrics in Proxmox

OOH! I can get this thing to visually display SMART data? neat! #

There’s some interesting shit one can do with ceph’s dashboard… Not that there aren’t multiple ways to represent this data, but I wanted to see how easy it’d be to get it represented… Fortunately, the Ceph Docs¹ are pretty good thus far.

There were a few things I had to install to get the monitoring components rolling… and it’s entirely possible there are more still; nevertheless, it appears that there’s two “simple” ways to get devices’ smart data polled a few times

for D in `ceph device ls-by-host \`hostname\` \
  |awk '{print $3}'|egrep -v DAEMONS`; do
  echo "`date` ${D}";
  ceph device scrape-daemon-health-metrics ${D};
done

ceph device scrape-health-metrics
