The monitor used to dump the pg status into the cluster log every 5 seconds, which was useful sometimes, but also made the log pretty unreadable for anything else, because other output was quickly swamped with the pg status spam. To replicate the de-facto old behaviour (print the pg status every 5 seconds), you can always do something like `watch -n1 "ceph status | grep pgs"` There's work ongoing to create a nice replacement that does a status stream without spamming the cluster log to accomplish it here: https://github.com/ceph/ceph/pull/20100 Cheers, John > > Here is what I get as initial output which is not updated: > > $ ceph -w > cluster: > id: d357a551-5b7a-4501-8d8f-009c63b2c972 > health: HEALTH_OK > > services: > mon: 1 daemons, quorum node1 > mgr: node1(active) > osd: 2 osds: 2 up, 2 in > rgw: 1 daemon active > > data: > pools: 11 pools, 152 pgs > objects: 9786 objects, 33754 MB > usage: 67494 MB used, 3648 GB / 3714 GB avail > pgs: 152 active+clean > > > > Even if I create a new volume in my Openstack installation, assign it to a > VM, mount it and format it, I have to stop and re-execute the "ceph -w" > command to see the following line: > > > io: > client: 767 B/s rd, 511 B/s wr, 0 op/s rd, 0 op/s wr > > which also pauses after the first display. > > > Kind regards, > > > G. > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
