Hi, All. We are using cephadm to manage a 19.2.0 cluster on fully-updated AlmaLinux 9 hosts, and would greatly appreciate help modifying or overriding the alert rules in ceph_default_alerts.yml. Is the best option to simply update the /var/lib/ceph/<cluster_id>/home/ceph_default_alerts.yml file? In particular, we’d like to either disable the CephPGImbalance alert or change it to calculate averages per-pool or per-crush_rule instead of globally as in [1]. We currently have PG autoscaling enabled, and have two separate crush_rules (one with large spinning disks, one with much smaller nvme drives). Although I don’t believe it causes any technical issues with our configuration, our dashboard is full of CephPGImbalance alerts that would be nice to clean up without having to create periodic silences. Any help or suggestions would be greatly appreciated. Many thanks, Devin [1] https://github.com/rook/rook/discussions/13126#discussioncomment-10043490
