cephadm (squid & tentacle) deploys alertmanager with some default alerts. One is CephNodeInconsistentMTU which checks if the MTU of each interface with the same name is the same across the cluster. However if your cluster nodes are not identical, and have differing interface names, we end up with lots of permanent alerts. Although I can silence the alert (matching the alert name) for a long time, they still show up in the dashboard. The alerts are different permutations of: Node ceph3 has a different MTU size (1500) than the median of devices named enp4s0. Since that check is inappropriate in a heterogeneous cluster, what's the recommended way of disabling it, which won't get overwritten with redeployment of the monitoring stack? Thanks, Chris
