Resource Management:Perform automatic tag detection

Procedure

The automatic tag detection feature can be used to check tag compliance of resources within the current account or the members in a resource directory. This section describes how to use a tag policy to automatically detect whether a tag whose tag key is CostCenter is added to all resources within the current Alibaba Cloud account.

1. Log on to the Resource Management console. The Tags page appears.

2. Create a tag policy.

   1. In the left-side navigation pane, choose Tag Policy > Policy Library. On the Policy Library page, click Create Tag Policy.

   2. On the Create Tag Policy page, enter a policy name in the Policy Name field.

   3. (Optional) Enter a policy description in the Policy Description field.

   4. Configure the tag policy on the Quick Mode tab.

      1. In the Tag Key field, enter CostCenter.

      2. Select Add Tags with Specified Tag Values to Resources for the Select Policy Scenario parameter.

      3. Enter one or more tag values in the Specify the allowed label values field.

         We recommend that you specify tag values based on the use scenario of the tag policy. The following use scenarios are supported:

         • Use the tag policy to detect resources to which tags with the specified tag key are not added

           In this scenario, you can use an asterisk (*) as a tag value. In this example, the tag key is CostCenter. If you set the tag value to * for the tag key, the tag policy is used to detect resources to which tags with the CostCenter tag key are not added.

           Note

           * indicates any tag value.

         • Use the tag policy to detect resources to which the specified tag is not added

           In this example, the tag key is CostCenter. If you set the tag value to Beijing for the tag key, the tag policy is used to detect resources to which the CostCenter:Beijing tag is not added.

           You can specify multiple tag values for each tag key. You must make sure that each tag value occupies one row.

   5. Click Create.

3. Attach the tag policy.

   Attach the tag policy created in Step 2 to the current Alibaba Cloud account. After the tag policy is attached to the account, the tag policy takes effect for the Alibaba Cloud account and the RAM users within the Alibaba Cloud account.

   For more information, see Attach a tag policy.

4. View the effective policy.

   An effective policy is obtained by aggregating all tag policies that are attached to the current account. For more information, see View an effective policy.

5. Wait until the detection tasks are complete and view the detection results.

   The system detects tag compliance of resources that belong to the Alibaba Cloud account and the RAM users within the Alibaba Cloud account and identifies the resources whose tags are non-compliant. You can view and download a report for the detection results.
