Querying Details of an Alarm Rule

Function

This API is used to query details of an alarm rule based on its ID.

For API V1, only an alarm rule can be configured for a single resource. You are advised to use Querying Alarm Rules (Recommended) and Querying Resources in an Alarm Rule to work with the console.

Debugging

You can debug the API in API Explorer which supports automatic authentication. API Explorer can automatically generate and debug example SDK code.
