Hi,

The activity on our ceph cluster has gone up a lot.  We are using exclusively

Is there a tool/technique that could be used to find out which rbd images are
receiving the most activity (something like "rbdtop")?



Are you using libvirt with KVM? If so, you can always poll all the disk 
I/O for all VMs using libvirt.



Thanks,
 Jeff

[ceph-users] ceph rbd io tracking (rbdtop?)

2013-08-12 Thread Jeff Moskow 
Hi,

The activity on our ceph cluster has gone up a lot.  We are using exclusively 
RBD
storage right now.

Is there a tool/technique that could be used to find out which rbd images are
receiving the most activity (something like "rbdtop")?

Thanks,
Jeff
