Creates an alert rule for a metric for a resource.

This topic provides an example to show how to create a threshold-triggered alert rule for the cpu_total metric for an Elastic Compute Service (ECS) instance whose ID is i-uf6j91r34rnwawoo**** instance. The namespace of ECS is acs_ecs_dashboard. The response shows that the alert contact 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 for Critical-level alerts is Average. The comparison operator for Critical-level alerts is GreaterThanOrEqualToThreshold. The threshold for Critical-level alerts is 90. The consecutive number of times for which the metric value meets the alert condition before a Critical-level alert is triggered is 3.

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.
