DimensionWhen the metric has multiple dimensions, optionally select one or more dimensions. For example, if a VM has multiple hard disks, then the disk read bytes metric may have a dimension for each disk

Last datapoints in period

The number of datapoints that the platform will evaluate the metric during the elapsed time.

If you request the evaluation of an alarm more frequently than metric data is collected by the platform or sent by the provider, then the alarm will not activate.

We recommend that you create alarms with longer evaluation periods, for example, an average of 10 points over the last hour, so the transmission and collection intervals will not affect the activation of the alarm.

Statistic

Statistic that the platform will use for evaluating the alarm, which can be: average, maximum, minimum, sum, count, dev

Formula

Operator that the platform will use for evaluation of the alarm, for example, greater than. Values can be: notequal, greaterthan, greaterthanorequalto, lessthan, lessthanorequalto, trendup, trenddown
