RDS for SQL Server

Tag management

Associate tag

RDS for SQL Server supports adding tags to instances, which enables the classification of SQL Server instances by tags and facilitates instance search and resource aggregation. This topic describes how to create tags and add them to instances.

Tag setting rules

The rules for tags setting are as follows:

Restrictions	Description
Tag key	Supports characters in any language, numbers, spaces, and the following special characters: _.:/=+-@. volc: is a system-reserved tag key. A tag key cannot start with volc:, in any uppercase or lowercase form. The tag key must be 1 to 128 characters long.
Tag value	Supports characters in any language, numbers, spaces, and the following special characters: _.:/=+-@. The tag value must be 0 to 256 characters long, which means it can be empty.
Number of tags	There is no limit on the total number of tags, but you can add up to 50 tags to each SQL Server instance. You can add up to 20 tags at a time.

Add a tag to a single instance

Log on to the RDS for SQL Server console.

In the upper-left corner of the top menu bar, select the project and region where the instance is located.

On the Instances page, find the target instance and click the edit icon in the Tag column. You can also click the name of the target instance and click the edit icon in the Tag row in the Basic information section.

In the Edit tag dialog box, set the Tag key and Tag value. Follow the tag setting rules when setting tags. For more information, see Tag setting rules. You can also click the Add tag button to add more tags.

Click OK.

Add tags to multiple instances

warning

If a new tag key matches an existing one on a selected instance, the new tag value will overwrite the current value.

Log on to the RDS for SQL Server console.

In the upper-left corner of the top menu bar, select the project and region where the instance is located.

In the instances, select all the instances that you want to tag, and then click Add tag in the lower-left corner of the page.

In the Add tag dialog, set the Tag key and Tag value. Follow the tag setting rules when setting tags. For more information, see Tag setting rules. You can also click the Add tag button to add more tags.

Click OK.
