I’m using Grafana with Graphite.
Suddenly (today) I got ‘Unauthorized’ (See attached image) on all
graphs within icinga. If I click on them I get the normal
Grafana page with the current graph.

So something happens when icingaweb tries to render the graph.
This has been working for many months without a problem.

I have icinga->apache_proxy->carbonapi->go-carbon so it isn’t obvious
which part is suddenly rejecting me.

My question is mostly, what component would generate the text?
It seems to be before grafana so I assume it is somewhere in icingaweb?

The message Cannot fetch Grafana graph seems to originate from the module. The remaining part however is not. Well, technically yes, but the status 401 not. So it’s a generic HTTP error which doesn’t provide a specific clue. Could be any part I guess, at least any part performing authentication.

I got it to work again by creating a user in Grafana and adding this to the grafana config in icinga. Strange. Seems as if Grafana got some new issue with anonymous login.

Well, at least it is working again… :slight_smile:
