[Matthew Stroud <mattstroud@xxxxxxxxxxxxx>]

Yeah, that is the core problem. I have been working with those teams that manage those. However, there isn’t a way I can check on my side as it appears.

His dilemma sounded like he has access to the cluster, but not any of the clients where the RBDs are used or even the hypervisors in charge of those.

Is there a way I could get a performance stats for rbd images? I'm looking for iops and throughput.

 

This issue we are dealing with is that there was a sudden jump in throughput and I want to be able to find out with rbd volume might be causing it. I just manage the ceph cluster, not the openstack hypervisors. I'm hoping I can figure out the offending volume with the tool set I have.

 

Thanks,

if you use a kernel mapped rbd image you should be able to get io stats from most stats tools, it will show as a regular block device.
