Hello,
I have a Grafana installation (version 10.1.5) running on a RHEL8 server. There are two datasources (Prometheus and Graphite). Both of the datasources are on the same server as the Grafana installation. Both have been working fine for quite some time but over the last days the Graphite datasource has been giving some problems.
If I test the Graphite datasource I get the response of “Data source is working” (most of the time, occasionally I get a Gateway timeout).
However even when the " Data source is working" message is displayed, dashboards which use the Graphite datasource fail to display any data. I just get the horizontal progress lines but nothing displayed.
I appreciate I need to provide more information, but it’s late where I am and just wanted to get this entered. I can provide more details in the morning.
My main question though is, are there any particular situations where a datasource would test as working but dashboards would fail to display data? The dashboard were working and no changes have been made.
Many thanks
Phil
