Troubleshooting

visualization & query issues

The most common problems are related to the query & response from you data source. Even if it looks like a bug or visualization issue in Grafana it is 99% of time a problem with the data source query or the data source response.

To check this you should use Query Inspector. Query Inspector shows query requests and responses.

A guide on how to use it you can find here.

Logging

If you encounter an error or problem it is a good idea to check the grafana server log. Usually located at /var/log/grafana/grafana.log on unix systems or in <grafana_install_dir>/data/log on other platforms & manual installs.

You can enable more logging by changing log level in you grafana configuration file.
