<p>Assigns one or more tags (key-value pairs) to the specified CloudWatch Logs resource. Currently, the only CloudWatch Logs resources that can be tagged are log groups and destinations. </p> <p>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.</p> <p>Tags don't have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.</p> <p>You can use the <code>TagResource</code> 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.</p> <p>You can associate as many as 50 tags with a CloudWatch Logs resource.</p>
