Configuration

• Q: In the data source configuration section, I am getting the error message invalid config. What does this mean?

• Q: In the data source configuration section, I am getting the error message unable to lookup Looker URL from the Grafana server. What does this mean?

  A: Mostly unable to lookup Looker URL from the Grafana server refers to either incorrect Looker URL or the Looker instance might not be reachable from the Grafana server.

• Q: In the data source configuration section, I am getting the error message unable to authenticate Looker instance. Potentially incorrect credentials provided. What does this mean?

  A: Mostly unable to authenticate Looker instance. Potentially incorrect credentials provided refers to incorrect client id and/or client secret. Ensure you are using correct credentials and credentials with correct permissions to query the data from the Looker instance

• Q: How do I validate the credentials outside Grafana instance to ensure I am providing correct credentials?

  A: If Grafana not able to connect with your Looker and still if you think the credentials are correct, you can cross verify this by running the following curl command from the host grafana server is running. curl --location 'https://xxxxxx.looker.app/api/4.0/login' --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode 'client_id=xxxxxx' --data-urlencode 'client_secret=xxxxxx'. The above command should get a successful api token. Otherwise, you need to fix your API credentials. Once you retrieve the token, you should be able to use this with curl --location 'https://xxxxxx.looker.app/api/4.0/lookml_models' --header 'Authorization: Bearer xxxxxx'
