How do I find my device names
logopk opened this issue · comments
Hi,
on the Grafana-dashboard from the repo my DISK Usage is "N/A".
The imported dashboard from grafana.com it shows Storage "No Data" and DISK Usage "N/A".
I see that in the collectd config I have to adjust my Devices. But the one from my df -h command will not change anything.
SELECT * FROM "df_value" WHERE ("host" =~ /^QNAP-collectd$/) is empty
How can I resolve this issue? What info can I provide?
Thank You.
Peter
huh, the df plugin is configured to show any sdX, mdX and nvmeX devices so I'm not sure why you aren't seeing anything.
Make sure you are running the collectd container on the NAS.
as for the config: cat /proc/mdstat

will show you (software) raid devices. you can probably ignore things like md13, md322, md256 etc. On my NAS only md1 and md2 are interesting.
Within these raids you can also see the individual devices:
md2 : active raid5 sdd3[0] sda3[3] sdb3[2] sdc3[1]
md1 : active raid5 sdh3[0] sde3[3] sdf3[2] sdg3[1]

Beware: I'm running on a remote monitoring system (in docker).
Oh and I'm seeing the disk IOPS for sda (variable disk name contains sda).
collectd has to run on the NAS itself. IOPS are gathered via SNMP, disk usage is gathered locally. I have not had time to migrate everything to SNMP yet.
OK. That explains it. Unfortunately I don't have a docker-capable QNAP (TS-269L).
I can live with it. Everything else is more than nice. So a big Thank You for the project.
