      Note

      • General-purpose instance: A general-purpose Prometheus instance is used for the remote storage of self-managed Prometheus clusters, or to monitor metric data about containers, cloud services, and hosts.

      • Global aggregation instance: A global aggregation instance is used to aggregate multiple Prometheus instances or self-managed Prometheus clusters, query Prometheus metrics, and manage Grafana data sources and alerts in a unified manner.

    Modify Prometheus instances

    After you create a Prometheus instance, you can modify the tags, storage duration, or billing method of the instance, or configure an aggregation instance for the instance.

    Manage tags

    You can add tags to various Prometheus instances to manage the instances by group. Each tag consists of a key and a value. You can use tag keys and values to further classify instances.

    Note

    • You can add a maximum of 20 tags to each instance, and the tag key must be unique. Duplicate tag keys are overwritten.

    • Tag information is not shared across regions.

    • If a tag is removed from all Prometheus instances, the tag is deleted.

    Add a tag to a Prometheus instance

    1. On the Instances page, select a region in the top navigation bar, find the Prometheus instance, and move the pointer over the image icon in the Tags column.

    2. Click Edit. The Configure Tags dialog box appears.

    3. Specify the Tag Key and Tag Value parameters and click OK.

    Query Prometheus instances by tag

    After you add tags to your Prometheus instances, you can query instances by tag.

    1. On the Instances page, select a region in the top navigation bar and click Filter by Tag in the Instances section.

    2. In the drop-down list that appears, select a tag key and value.

    Remove a tag from a Prometheus instance

    You can remove a tag from a Prometheus instance.

    1. On the Instances page, select a region in the top navigation bar, find the Prometheus instance, and move the pointer over the image icon in the Tags column.

    2. Click Edit. The Configure Tags dialog box appears.

    3. Find the tag that you want to remove, click the image.png icon, and then click OK.

    Change the billing method of a Prometheus instance

    Managed Service for Prometheus has provided the pay-as-you-go and subscription billing methods, and the pay-by-observable-data billing mode. You can change the pay-as-you-go or subscription billing method to the pay-by-observable-data billing mode. For more information, see Billing modes.

    Change the storage duration of a Prometheus instance

    The default storage duration is 90 days. If you want to store the data of a Prometheus instance for a longer period, you can change the storage duration on the Storage Duration tab of the Settings page.

    1. On the Instances page, select a region in the top navigation bar and click the name of the instance to go to the instance details page.

    2. In the left-side navigation pane, click Settings. On the page that appears, click the Storage Duration tab.

    3. On the Storage Duration tab, select the storage duration and click Save.

      Note

      • A storage duration of 90 days or 180 days is supported.

      • You cannot set the storage duration for a Prometheus instance for Alibaba Cloud services that is used to monitor an Alibaba Cloud service, such as ECS, MongoDB, or Tair. For information about Prometheus instance types, see What is Managed Service for Prometheus?

    Configure a global aggregation instance

    After you create a global aggregation instance, you can use the instance to aggregate other Prometheus instances for unified monitoring and management. Perform the following steps:

    1. On the Instances page, select a region in the top navigation bar, find the global aggregation instance, and click Edit in the Actions column.

    2. In the Edit Aggregate Instance panel, select the Prometheus instances that you want to aggregate, and click Edit Aggregate Instance.

      Select an Alibaba Cloud account and the Prometheus instances that you want to aggregate.

    Important

    After a Prometheus instance is deleted, the monitoring data, dashboard, alert rules, and service discovery configurations of the instance are deleted and cannot be restored. Proceed with caution.

    1. On the Instances page, select a region in the top navigation bar and click Uninstall in the Actions column.
