This topic describes the metrics for ApsaraDB for MongoDB of the sharded cluster architecture.
When you call an API operation provided by Cloud Monitor, you may need to set the Namespace and Period parameters. Set the parameters for the current service in the following way:
- Set the Namespace parameter to acs_mongodb.
- Set the Period parameter to an integral multiple of 60s. The default value is 60s.
The following table describes the valid values of the MetricName and Dimensions parameters for the current service.
