Hello, I recently started to use a postgresql datasource in my Grafana dashboards. Unfortunately it seems to run into some timeout issue for more complex queries after approx. 1 minute (“request error” without further details).
Can you confirm that there is such a time limit and is there a way to extend it?
Best,
I thought the timeout was 30 seconds - if you look in your Chrome Dev Tools console, do you get a more detailed error there? (Or in the grafana server logs).
Long queries is very much an edge case for Grafana. Most timeseries queries should complete within in a second or two.
There is a feature request for adding a configuration option for query timeouts but it is not implemented: https://github.com/grafana/grafana/issues/3168
