Hello, Is there a way to get read/write I/O statistics for each rbd device for each mapping? For example, when an application uses one of the volumes, I would like to find out what performance (avg read/write bandwidth, IOPS, etc) that application observed on a given volume. Is that possible? Thanks, Shridhar
Hi Shridhar, Did u mean 'ceph rbd perf image stats' or 'rbd perf image iostat' ? for monitor intergration, you can enable mgr prometheus module and get metrics for each image in specified pools ------------------ Original ------------------ From: "Void Star Nill"<void.star.nill@gmail.com>; Date: Thu, May 7, 2020 10:18 AM To: "ceph-users"<ceph-users@ceph.io>; Subject: [ceph-users] per rbd performance counters Hello, Is there a way to get read/write I/O statistics for each rbd device for each mapping?
