Description Juan Miguel Olmo 2022-11-23 18:33:26 UTC

As developer i need to extend the information about RBD image status present in RADOS in order to have information about the last synchronization operation.

The extra fields to store in the image status are:

snap_last_sync_duration: time used to execute the last sync
snap_last_bytes_transferred: number of bytes transfer on last sync operation

This information will be included in the output of CLI commands (exampl, rbd mirror image status) and as labels in the ceph_rbd_image_status metric provided by Prometheus manager module

Solved in :
https://github.com/ceph/ceph/pull/49299

Example of the metrics provided by Ceph Exporter:

3365:# HELP ceph_rbd_mirror_snapshot_image_last_sync_bytes Bytes synced for the last snapshot
3366:# TYPE ceph_rbd_mirror_snapshot_image_last_sync_bytes gauge
3367:ceph_rbd_mirror_snapshot_image_last_sync_bytes{ceph_daemon="client.admin.40628",image="image1",namespace="",pool="data"} 52428800
3368:# HELP ceph_rbd_mirror_snapshot_image_last_sync_time Time taken to sync the last snapshot
3369:# TYPE ceph_rbd_mirror_snapshot_image_last_sync_time gauge
3370:ceph_rbd_mirror_snapshot_image_last_sync_time{ceph_daemon="client.admin.40628",image="image1",namespace="",pool="data"} 0.000000
