Grafana: Graphs in ceph-pools reporting double write IOPS
This was originally reported in the openATTIC issue tracker as OP-2703:
Graphs for the pools are showing double the write IOPS that are actually being produced. Read IOPS are showing the correct number. MB/s is showing the correct number as well.
Can you please verify the Ceph Pools Grafana dashboard in that respect? Thanks!
So I think the problem is that ceph reports IOP/s as a running average not as a current value. This does not work well with prometheus and grafana. At the moment it looks like this graph will go away when the switch to the mgr prometheus plugin for this reason. Will keep this open for a bit for further discussion.
Is this still a thing?
