Checking Prometheus Instance Data Through Grafana

Prerequisites

• You have created an ECS.
• You have created an EIP and bound it to the created ECS. For details, see Elastic Cloud Server (ECS) Getting Started.
• Your service has been connected for Prometheus monitoring. For details, see Managing Prometheus Instances.

Procedure

1. Install and start Grafana. For details, see the Grafana official documentation.
2. Add an access code.
   1. Log in to the AOM 2.0 console.
   2. In the navigation pane, choose Settings. The Global Settings page is displayed.
   3. On the displayed page, choose Authentication in the navigation pane. Click Add Access Code.
   4. In the dialog box that is displayed, click OK. The system then automatically generates an access code.

      An access code is an identity credential for calling APIs. A maximum of two access codes can be created for each project. Keep them secure.

3. Obtain the Grafana data source configuration code.
   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.
   3. On the displayed page, choose Settings in the navigation pane and obtain the Grafana data source information from the Grafana Data Source Info area.

4. Configure Grafana.
   1. Log in to Grafana.
   2. In the navigation pane, choose Configuration > Data Sources. Then click Add data source.

   4. Set Grafana data source parameters.
      • URL: HTTP URL obtained in 3.c.
      • User: username obtained in 3.c.
      • Password: password obtained in 3.c.

      The Basic auth and Skip TLS Verify options under Auth must be enabled.

      If the current version supports the configuration of performance parameters under Advanced settings, set Prometheus type to Cortex and Cortex version to 1.0.0.

      

   5. Click Save&Test to check whether the configuration is successful.

      If the configuration is successful, you can use Grafana to configure dashboards and view metric data.
