Monitoring checkpoint latency for cluster replication
Learn how to monitor the checkpoint latency of a Kafka cluster replication in Streams Messaging Manager (SMM). You can monitor average, maximum, and minimum checkpoint latency of a cluster replication. You can also monitor the checkpoint latency of a cluster replication graphically.
Checkpoint latency is defined as the amount of time taken for a message of a topic to checkpoint on the target cluster after the message is committed on the source cluster. Checkpoint latency is measured in milliseconds.
In the image, you can see the average checkpoint latency for the CDFCluster to CDFClusterDR replication is 4.6 milliseconds. You can fetch the maximum or minimum replication latency for the replication by clicking the MAX or MIN button located above the cluster replication.
