Modifying an Alarm Masking Rule

Function

This API is used to modify an alarm notification masking rule.

You cannot modify the alarm masking rules for masking alarms by alarm rules, but you can modify those for masking alarms by resource, policy, and event.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.
