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.
So make sure to check the query sent and the raw response, learn how in this guide: How to troubleshoot metric query issues
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.
