Ceph Device metrics in Proxmox
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
with an open session on each ceph host; you can parallelize the inspection and have it run a bit faster:
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
