AWS RDS: Replica Lag
Distribution offizieller Teil von Check_MK
Lizenz GPL
Unterstützte Agenten Aws

This check monitors the time a read replica DB instance lags behind the source DB instance. For PostgreSQL databases, the check also monitors the lagging size of the replica lagging the most in terms of write-ahead log (WAL) data received (OldestReplicationSlotLag). To make this check work you have to configure the related special agent {Amazon Web Services (AWS)}. No default levels are set. Upper levels are configurable for the replica lag age and oldest replication slot lag size via the rule "AWS/RDS Replica lag".

Item

Name of the instance and region name (to avoid duplicate services in case of multi-region monitoring).

Discovery

One service is created for each database if all required metrics (ReplicaLag) are given.
