Description
A recent change https://tracker.ceph.com/issues/43975 logs details for each slow request and sends to monitors
But on large cluster, it could overwhelm monitors with spurious logs when performance issue happens, and cause further instability in the cluster
In our case, ceph.log growed to more than 14GB quickly, and we need to restart all monitors to recover
This was added in Nautilus (14.2.10) and Octopus (15.2.0)
Would it be better to have a configuration to turn this on/off, so we can disable logging details for every slow requests to monitors if necessary
