This topic describes the metrics of ApsaraDB RDS.
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_rds_dashboard.
- Set the Period parameter to an integral multiple of 60s. The default value is 60s.
Note Among ApsaraDB RDS for SQL Server instances with the Microsoft SQL Server database
engine, only the instances whose SQL Server version is 2008 R2 support the ConnectionsUtilization
and MemoryUtilization metrics.
The following table describes the valid values of the MetricName and Dimensions parameters for the current service.
