Creating a Prometheus connection

To create a Prometheus connection:

1. Open the page for creating a new connection.

2. Under Databases, select the Prometheus connection.

3. Specify the connection parameters:

   • Hostname: Specify the path to the Prometheus host. You can specify multiple hosts in a comma-separated list. If you are unable to connect to the first host, DataLens will select the next one from the list.
   • Port: Specify the Prometheus connection port.
   • URL: Specify the URL of the Prometheus API.
   • Username: Specify the username for the Prometheus connection.
   • Password: Enter the password for the user.
   • Cache TTL in seconds: Specify the cache time-to-live or leave the default value. The recommended value is 300 seconds (5 minutes).
   • HTTPS: Enable the secure connection option if your server supports HTTPS.

4. (Optional) Make sure the connection works properly. To do this, click Check connection.

5. Click Create connection.

6. Select a workbook to save your connection to or create a new one. If using legacy folder navigation, select a folder to save the connection to. Click Create.

7. Enter a name for the connection and click Create.
