Managing Tags

Scenarios

Tag Management Service (TMS) enables you to manage resources using tags on the management console. TMS works with other cloud services to manage tags. TMS manages tags globally and other cloud services manage their own tags.

Adding tags to GeminiDB Influx instance helps you better identify and manage them. An instance can be tagged when or after it is created.

After a DB instance is tagged, you can search for the tag key or value to quickly query the instance details.

Precautions

• You are advised to set predefined tags on the TMS console.
• A tag consists of a key and value. You can add only one value for each key. For details about naming rules of tag keys and tag values, see Table 1.
• Each instance can have up to 20 tags by default.
• The tag name must comply with the naming rules described in Table 1.

  Table 1 Naming rules

  Parameter	Requirement	Example Value
  Tag key	Cannot be left blank. Must be unique for each instance. Can contain a maximum of 36 characters. Can only consist of digits, letters, underscores (_), and hyphens (-).	Organization
