Monitoring Amazon DocumentDB Global Clusters
Amazon DocumentDB (with MongoDB compatibility) integrates with CloudWatch so that you can gather and analyze operational metrics for your clusters. You can monitor these metrics using the CloudWatch console, the Amazon DocumentDB console, the Amazon Command Line Interface (Amazon CLI), or the CloudWatch API.
To monitor a global cluster, use the following CloudWatch metrics.
Metric | Description |
---|---|
GlobalClusterReplicatedWriteIO |
The average number of billed write I/O operations replicated from the
cluster volume in the primary Amazon Web Services Region to the cluster volume in a secondary
Amazon Web Services Region, reported at 5-minute intervals. The number of replicated
ReplicatedWriteIOs to each secondary region is the same as the
number of in-region VolumeWriteIOPs performed by the primary
region. |
|
The amount of data transferred from the primary cluster’s Amazon Web Services Region to a secondary cluster’s Amazon Web Services Region, measure in bytes. |
|
The amount of lag, in milliseconds, when replicating change events from the primary cluster’s Amazon Web Services Region to a secondary cluster’s Amazon Web Services Region |
