Configuring the Remote Read Address to Enable Self-built Prometheus to Read Data from AOM

Constraints

When configuring Prometheus for remote read, ensure that global:external_labels**: is correct since external_labels will be added to the search criteria. If a label is incorrect, required data may fail to be queried.

You can set filter_external_labels: false (Prometheus: v2.34 or later) to prevent external_labels from being added to the search criteria.

Prerequisite

Your service has been connected for Prometheus monitoring. For details, see Managing Prometheus Instances.

Configuring the Remote Read Address

You are advised to configure the prometheus.yml file of self-built Prometheus. Procedure:

1. Log in to the AOM 2.0 console.
2. In the navigation pane on the left, choose Prometheus Monitoring > Instances. In the instance list, click the target Prometheus instance to go to the details page.
3. In the navigation pane on the left, choose Settings. On the Intranet or Public Network tab page in the Service Addresses area, click on the right to copy the configuration code for Prometheus remote read.

   remote_read:
     - url: 'https://aom.{region_name}.{Site domain name suffix}/v1/{project_id}/{prometheus_instance_id}/api/v1/read'
       tls_config:
         insecure_skip_verify: true
        bearer_token: '8H**LP'
        read_recent: true

4. Add the copied configuration code to the prometheus.yml file of self-built Prometheus.
5. Restart the self-built Prometheus service.

   Then you can view AOM Prometheus data.
