Description Neil Levine 2016-11-23 22:27:58 UTC

User Story:

As an admin, I want to see which RBD clients by IP address are generating the most IOPS so I can spot noisy hosts on my client network.

As an admin, I want to see which RBD clients by Virtual Machine on a hypervisor are generating the most IOPS so I can spot noisy neighbors in an OpenStack environment

Notes:

It is expected that that this will be implemented on top of ceph-mgr.
