Hello, I have a Ceph cluster (3x storage 2x monitor). Zabbix is monitoring physical disks (bandwidth, ops), CPU, RAM etc. - OK. I created block devices in Ceph by "rbd" command. The block devices are accesible throught iSCSI Target (read/write data).
And I need to know, is it possible to monitor block devices (bandnwith, ops)? And if yes, how?
I can monitor physical disk with "vfs.dev.write[/dev/sda,ops]" key. But something like "vfs.dev.write[rbd4,ops]" does not work - no error, just 0 data.
And I need to monitor CPU usage for each block device distributed over Ceph cluster for each connected user. Is it even possible? It does not have to be Zabbix. Any other tool would help too.
Thank you for you help.
