Selecting Dimensions for an Alarm Query
Limit the metric data that's returned by selecting dimensions for an alarm in Monitoring. A dimension is a qualifier provided in a metric definition. In MQL, the dimension selection component specifies name-value pairs for dimensions, surrounded by curly brackets.
For alarm troubleshooting, see Troubleshooting Alarms. See also Creating a Basic Alarm.
