Selecting the Interval for an Alarm Query

Select the interval, or time window, for querying metric data in an alarm in Monitoring.

For valid interval options in MQL expressions, see Interval (Monitoring Query Language (MQL) Reference).

Illustration

The timestamp of the aggregated data point corresponds to the end of the time window during which raw data points are assessed. For example, for a five-minute interval, the timestamp "2:05" corresponds to the five-minute time window from 2:00:n to 2:05:00.

For alarm troubleshooting, see Troubleshooting Alarms.
