Creates an alert rule for a metric of a resource.

This topic provides an example of how to create a threshold-triggered alert rule for the cpu_total metric of the i-uf6j91r34rnwawoo**** instance in the acs_ecs_dashboard cloud service. The response indicates that the alert group of the alert rule is ECS_Group, the name of the alert rule is test123, and the ID of the alert rule is a151cd6023eacee2f0978e03863cc1697c89508****. The statistical method is Average, the comparison operator is GreaterThanOrEqualToThreshold, the threshold is 90, and the consecutive number of times for which the metric value is measured before a critical-level alert is triggered is 3 for critical-level alerts.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

The mute period during which notifications are not repeatedly sent for an alert. Unit: seconds. Default value: 86400.

Note If an alert is not cleared within the mute period, a new alert notification is sent when the mute period ends.
Interval String No 60

The interval at which the alert is triggered. Unit: seconds.

Note For more information about how to query the statistical periods of metrics, see Appendix 1: Metrics.
EmailSubject String No Alert for an ECS instance

The subject of the alert notification email.

Period String No 60
