I made following change in /etc/grafana/grafana.ini
[log]
mode = console
level = warn
[log.console]
level = warn
But I still see debug info in docker logs. Like the following
{"@level":"debug","@message":"datasource: registering query type handler","@timestamp":"2021-08-16T11:51:13.946436Z","queryType":"exponential_heatmap_bucket_data"}
