Metricstores of Log Service are compatible with the query API of Prometheus. This topic describes how to connect Log Service as a Prometheus data source to Grafana. You can then send data from Log Service to Grafana and visualize the data in Grafana.

Prerequisites

Configure Log Service as a Prometheus data source in Grafana

  1. Log on to Grafana.
  2. In the left-side navigation pane, choose Configuration > Data Sources.
  3. On the Data Sources tab, click Add data source.
  4. Move the pointer over the Prometheus card and click Select.
  5. On the Settings tab, set the following parameters.
    Parameter or section Description
    Name Set a name for the data source, for example, Prometheus-01.
    HTTP
    • URL: Enter the URL of the Metricstore. Format: https://{project}.{sls-enpoint}/prometheus/{project}/{metricstore}. Replace {sls-enpoint} with the Log Service endpoint in the region where the project resides. For the list of Log Service endpoints in different regions, see Endpoints. Replace {project} and {metricstore} with the project name and Metricstore name. Example: https://sls-prometheus-test.cn-hangzhou.log.aliyuncs.com/prometheus/sls-prometheus-test/prometheus.
      Note To ensure secure transmission, use HTTPS.
    • Whitelisted Cookies: Specify a whitelist for access. This parameter is optional.
    Auth Select the Basic Auth check box.
    Basic Auth Details
    • User: Enter an AccessKey ID.
    • Password: Enter an AccessKey secret that corresponds to the AccessKey ID.
    We recommend that you use an AccessKey pair of a RAM user that has only the permissions to read data from the Log Service project. For information about how to grant a RAM user only the permissions to read data from a specified Log Service project, see The read-only permission on projects.
  6. Click Save & Test.

Import a Log Service dashboard template to Grafana

Perform the following steps to import a Log Service dashboard template to Grafana:

  1. Copy the template ID.
    1. Log on to the dashboard market of Grafana.
    2. Click the template.
    3. On the right side of the page, click Copy ID to Clipboard.
  2. Log on to Grafana.
  3. In the left-side navigation pane, choose Create > Import.
  4. In the Grafana.com Dashboard field, paste the template ID that you copied in Step 1.

    Then, click a blank area to go to the page for data source configuration.

  5. Configure the data source.

    In this step, set the parameters based on the data source that you added when you configure Log Service as a Prometheus data source in Grafana. The parameters vary depending on the dashboard template. The parameters may include telegraf and host.

  6. Click Import.
