When creating alarm rules, you can set alarm tags and annotations. Tags are attributes that can be used to identify alarms. They are applied to alarm noise reduction scenarios. Annotations are attributes that cannot be used to identify alarms. They are applied to scenarios such as alarm notification and message templates.

Alarm Tag Description

Alarm tags can apply to grouping rules, suppression rules, and silence rules. The alarm management system manages alarms and notifications based on the tags.
Each tag is in "key:value" format and can be customized. Each key and value can contain only letters, digits, and underscores (_).
If you set a tag when creating an alarm rule, the tag is automatically added as an alarm attribute when an alarm is triggered.
In a message template, the $event.metadata.key1 variable specifies a tag. For details, see Table 2.

NOTE:

If tag policies related to AOM have already been set, add alarm tags based on these policies. If a tag does not comply with the policies, tag addition may fail. Contact your organization administrator to learn more about tag policies.

Alarm Annotation Description

Annotations are attributes that cannot be used to identify alarms. They are applied to scenarios such as alarm notification and message templates.
Each annotation is in "key:value" format and can be customized. You can create up to 10 custom annotations. The key and value can only contain letters, digits, and underscores (_).
In a message template, the $event.annotations.key2 variable specifies an annotation. For details, see Table 2.
