Hi, I just noticed across different Ceph versions that when browsing the dashboard, the MGR is logging lots of prometheus queries for the balancer status: Sep 30 11:15:55 host2 ceph-mgr[3993215]: log_channel(cluster) log [DBG] : pgmap v25341: 381 pgs: 381 active+clean; 3.9 GiB data, 69 GiB used, 311 GiB / 380 GiB avail; 954 B/s rd, 1 op/s Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:56 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:57 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch Sep 30 11:15:59 host2 conmon[3993190]: 192.168.168.62 - - [30/Sep/2024:09:15:59] "GET /metrics HTTP/1.1" 200 71320 "" "Prometheus/2.33.4" Sep 30 11:16:02 host2 ceph-mgr[3993215]: log_channel(audit) log [DBG] : from='mon.1 -' entity='mon.' cmd=[{"prefix": "balancer status", "format": "json"}]: dispatch At least I assume that this is prometheus if I interpret [0] correctly. In this case, the balancer is even disabled. Why is it necessary to query the balancer status that often? I couldn't find any useful config related to this. This was noticed on Pacific (16.2.15) and Squid (19.1.1), both with Prometheus version 2.33.4. I haven't tried other Prometheus versions yet. I will check it with a newer Prometheus version as well.
