CloudWatchObservabilityAccessManager / Client / tag_resource



Assigns one or more tags (key-value pairs) to the specified resource. Both sinks and links can be tagged.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.

Tags don’t have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.

You can use the TagResource action with a resource that already has tags. If you specify a new tag key for the alarm, this tag is appended to the list of tags associated with the alarm. If you specify a tag key that is already associated with the alarm, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a resource.


Unlike tagging permissions in other Amazon Web Services services, to tag or untag links and sinks you must have the oam:ResourceTag permission. The iam:ResourceTag permission does not allow you to tag and untag links and sinks.
