Tag is a mark provided by Tencent Cloud for identifying cloud resources, and is a key-value pair (Key-Value). Tags help you conveniently classify and manage TDMQ for MQTT resources from various dimensions (such as business, purpose, responsible person, and so on).
Note:
Tencent Cloud does not use the tags you set; tags are only used for your management of TDMQ MQTT resources.

Usage Examples
Case Description
Case: A company has 6 Message Queue for MQTT clusters on Tencent Cloud. The usage departments, business scopes, and responsible personnel information for these 6 clusters are as follows:
Queue ID
Department
Business Scope
Owner
mqtt-qg40xwvj
E-commerce
Marketing campaigns
Tom
mqtt-qg41xwvj
E-commerce
Marketing campaigns
Harry
mqtt-qg42xwvj
Gaming
Game A
Jerry
mqtt-qg43xwvj
Gaming
Game B
Harry
mqtt-qg44xwvj
Entertainment
Post-production
Harry
mqtt-qg45xwvj
Entertainment
Post-production
Tom
Take mqtt-qg40xwvj as an example, we can add the following three sets of Tags to this instance:
Tag Key
Tag Value
dept
ecommerce
business
mkt
owner
tom
Similarly, you can also set appropriate tags for other queue resources based on their departments, business scopes, and owners.
Setting Tags in the TDMQ for MQTT Console
When we take the above scenario as an example, after designing the tag keys and values, you can log in to the TDMQ for MQTT console to set tags.
2. On the Cluster page, select a region, select the clusters for which you want to edit tags, and click Edit Resource Tag at the top of the page.
3. In the Edit Tags pop-up window, set tags.
For example: add three sets of tags to the amqp-qg40xwvj cluster.
Note:
If the existing tags do not meet your requirements, go to the Tag Management page to create tags.
4. Click OK, and the system will display a message indicating that the modification is successful. You can view the bound tags in the Resource Tag column of the cluster.
Filtering Resources by Tag Key
To filter out the clusters bound to specific tags, perform the following steps:
1. Select tag in the search box at the top-right corner of the page.
2. In the window displayed after Tag:, select the tag you want to search for and click OK.
3. For example: select Tag: owner:zhangsan to filter clusters bound to the tag key owner:zhangsan.
Editing Tags
1. On the cluster management list page, select a region and the clusters for which you want to edit tags, and click Edit Resource Tags at the top of the page.
Note:
You can edit tags for up to 20 resources in batches.
2. In the Edit Tags pop-up window, add, modify, or delete tags based on actual needs.
Managing Resource Tags in a Unified Manner
You can also manage resource tags in a unified manner in the Tag console. The detailed steps are as follows:
