grafana_image_renderer fails with http 401 #256

Closed emtie closed 3 years ago

emtie commented 3 years ago

What happened: I have configured icingaweb2 to show grafana dashboards inplace to have a nice overview incinga. But when I open a page which should show grafana graphs I get an errormessage which says: "Cannot fetch graph with curl: Operation timed out after 5001 milliseconds with 0 bytes received. When I click on the link the grafana webpage opens and shows the expected graph just fine!

The grafana environment is running as docker containers in a docker swarm. the definition is like that:

 version: '3.7'
 services:
   grafana:
     image: grafana/grafana:latest
     ports:
       - "3000:3000"
     volumes:
       - /gluster/docker/volume/grafana/etc:/etc/grafana
       - /gluster/docker/volume/grafana/lib:/var/lib/grafana
     environment:
       - GF_INSTALL_PLUGINS=grafana-clock-panel,grafana-simple-json-datasource
       - GF_RENDERING_SERVER_URL=http://grafana_renderer:8081/render
       - GF_RENDERING_CALLBACK_URL=https://grafana_grafana:3000/
       - GF_LOG_FILTERS=rendering:debug
   renderer:

       - IGNORE_HTTPS_ERRORS=true
       - BROWSER_TZ=Europe/Berlin

The containerlogs show the following:

What you expected to happen: I would love to see the beautyful grafana graphs to be displayed in icingaweb2

How to reproduce it (as minimally and precisely as possible): see description above

Anything else we need to know?: don't no. you are welcome to give me some advice which further information I can provide to help solve the issue...

Environment:

Thanks in advance!

I think you need to find a way to increase the timeout on icingaweb2 because 5s can be too short for the rendering requests depending on the requests you are doing. We are looking into ways to improve performance but it's a different issue (see https://github.com/grafana/grafana-image-renderer/issues/124).
