What happened: Rendering fails

What you expected to happen: Rendering to succeed

How to reproduce it (as minimally and precisely as possible): Start the Grafana server, choose a panel and click "Direct link rendered image" and it says Grafana / Server Error... Rendering failed... Check the Grafana server logs for more details.

And the /var/log/grafana/grafana.log contains:

Anything else we need to know?: It looks like this is likely being caused by the fact that I am using nginx to redirect https://ourgitlabinstance.com/grafana to 127.0.0.1:3001 with proxypass and the rendering request has a path of path=/render/... which may be the problem? ...because in my case it would need to be path=grafana/render/? I'm not sure where remote_addr is getting populated but maybe it would work if it was the loopback?

Environment:

marefr commented 4 years ago

You have to save the dashboard first.

TryTryAgain commented 4 years ago

The dashboard was saved, just tried again with a previously saved and unmodified dashboard as well. @marefr What made you think that was the reason for it not working?

marefr commented 4 years ago

Sorry, thought I read /new-dashboardurl.

marefr commented 4 years ago

Please include your Grafana config (replace any sensitive information), specifically interested in your server and rendering settings together with your reverse proxy setup. I think you have to configure the callback_url, see https://grafana.com/docs/grafana/latest/installation/configuration/#callback-url

TryTryAgain commented 4 years ago

@marefr, ah, that's understandable as it was called /new-dashboard-copy-test :)

If you can browse http://127.0.0.1:3001/d-solo/IEfxMsQWz/new-dashboard-copy-testing?orgId=1&from=1582139966395&to=1582312766395&panelId=2 then config should be all good and you have a problem with the image renderer/chromium.

TryTryAgain commented 4 years ago

@marefr I can navigate to the d-solo resulting image, although in my case I have to remove an added /render/ that comes between my subdir//grafana and the /d-solo/.

I have installed all dependencies: yum install [...] results in [...] already installed and latest version Nothing to do.

I will try a variety of versions, have not yet. I'll report back on that...

...but, it works without issue as expected when using custom-chrome-chromium!

marefr commented 4 years ago

@TryTryAgain v1.0.11 is released which enables you to enable verbose logging, for plugin thru environment variable see https://github.com/grafana/grafana-image-renderer/blob/master/README.md#environment-variables. Please try enabling that and report back Grafana server log output. Thanks
