RDSReplicationLag

Alerts on replication lags (if lag is above 10 ms for at least 15 mins)

Troubleshooting Hints

Note we have no ways to check for network issues. - Check replication status - Check the pg_stat_activity to check if there is a lot of insert query made recently - Check if wal_level = replica and max_wal_senders > number of replicas

Solutions

• If the issue persists and there is not a bunch INSERT query in flight, open an issue to the FE support.
