Hi,
It is possible to get statistics of issued reads/writes to specific RBD image?
Best will be statistics like in /proc/diskstats in linux.

Yes, you just need to enable the "admin socket" in your ceph.conf and then use
"ceph --admin-daemon /path
Thank You for help, it is exactly that I need.

Yup, on the host
Hello again,
How can I determine $cctid for specific rbd name? Or is there any good way to
map admin-socket with rbd?

If one VM is using multiple rbd’s then using just $pid is not enough. Socket
shows only one (first) rbd statistics.

OK, it will be nice feature if we can get name of rbd from admin socket, at now
I’m doing this in the way you wrote.
Thanks for help,

Hi,
If it’s problem with UUID of partition You can use this commands:
sgdisk --change-name={journal_partition_number}:'ceph journal'
--typecode={journal_partition_number}:45b0969e-9b03-4f30-b4c6-b4b80ceff106
--mbrtogpt -- /dev/{journal_device}
sgdisk --change-name={data_partition_number}:'ce
