Hello. I've got two DCs with 8 hardware servers on each. After migration to Cassandra 4 I have strange messages in system.log:
INFO [ScheduledTasks:1] 2022-04-12 12:05:58,595 MessagingMetrics.java:206 - MUTATION_RSP messages were dropped in last 5000 ms: 0 internal and 241 cross node. Mean internal dropped latency: 0 ms and Mean cross-node dropped latency: 2395 ms INFO [ScheduledTasks:1] 2022-04-12 12:05:58,596 MessagingMetrics.java:206 - MUTATION_REQ messages were dropped in last 5000 ms: 0 internal and 8 cross node. Mean internal dropped latency: 0 ms and Mean cross-node dropped latency: 2395 ms INFO [ScheduledTasks:1] 2022-04-12 12:05:58,596 MessagingMetrics.java:206 - PAXOS_COMMIT_RSP messages were dropped in last 5000 ms: 0 internal and 102 cross node. Mean internal dropped latency: 0 ms and Mean cross-node dropped latency: 2395 ms Can someone interpret these messages? I suspect that messages indicate that the cluster has some replication issues.
