Multi-Region Cadence Replication Metrics

These metrics are specific to the Replication Tasks in History service of Multi-Region Cadence clusters.

Replication Task

Replication Task metrics can be used to monitor the replication of workflow execution across multi-region Cadence clusters. To utilise the multi-region functionality, please refer to our support documentation page on how to Create a Multi-Region Cadence Cluster.

Applied Replication Tasks / sec: This is the average number of successfully applied replication tasks.
Average Replication Task Applied Latency: This is the average latency from replication tasks being received to them being applied, in milliseconds.
Average Replication Task Latency: This is the average latency from replication tasks being created to them being applied, in milliseconds.
Replication Tasks Cleanup Count / sec: This is the average number of cleaned up replication tasks after being acknowledged by the standby Cadence cluster.
Replication Tasks Cleanup Failed Count / sec: This is the average number of replication tasks failed to be cleaned up after being acknowledged by the standby Cadence cluster.
Replication DLQ Size: This is the size of the DLQ of replication tasks that could not be applied after retry.
Replication DLQ Enqueue Failed Count / sec: This is the average number of replication tasks that could not be applied after retry and are failed to be put into DLQ.
