    Create, delete, and manage Prometheus instances. Configure tags, billing methods, storage duration, and aggregation settings.

    Prerequisites

    ARMS is activated. Activate ARMS.

    Access the instance list

    1. Log on to the ARMS console.

    2. In the left navigation pane, choose Managed Service for Prometheus > Instances.

    2. On the Create instance page, set the parameters and click Create Now.

    Edit an instance

    After creating a Managed Service for Prometheus instance, configure tags, billing method, storage duration, and aggregation settings.

    Manage tags

    Tags are key-value pairs that categorize instances.

    Note

    • Each instance supports up to 20 tags. Keys must be unique; adding a duplicate key overwrites the value.

    • Tags are specific to a region.

    • Unbound tags are automatically deleted.

    Create a tag

    1. On the Instances page, select a region from the top navigation bar. Then, in the Tag column for the target instance, click the image icon.

    2. Click Edit to open the Edit Tag tab.

    3. Enter a Tag Key and Label Value, then click OK.

    Filter instances by tag

    Use assigned tags to filter instances.

    1. On the Instances page, select a region from the top navigation bar. Then, on the Instances tab, click Filter by tag.

    2. Select a tag key and value.

    Remove a tag

    Remove unused tags from instances.

    1. On the Instances page, select a region from the top navigation bar. Then, in the Tag column for the target instance, click the image icon.

    2. Click Edit to open the Edit Tag tab.

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

    Change the billing method

    Prometheus supports pay-as-you-go, subscription, and pay-by-observable-data billing. Switch from pay-as-you-go or subscription to pay-by-observable-data. Switch billing methods.

    Set the storage duration

    Data is stored for 90 days by default. To extend retention, adjust the setting on the Retention Period page.

    1. On the Instances page, select a region from the top navigation bar, then click the target instance name.

    2. In the left-side navigation pane, click Modify, then click the Retention Period tab.

    3. On the Storage Days tab, select the desired storage duration, then click Save.

      Note

      Supported values: 90 or 180 days.

    Configure aggregation instances

    A global aggregation instance consolidates data from multiple Prometheus instances for centralized monitoring and management.

    1. On the Instances page, select a region from the top navigation bar. Then, in the Actions column of the target instance, click Edit.

    2. On the Edit aggregate instance page, select the instances to aggregate and click Edit aggregate instance.
