Please try to fill out as much of the information below as you can. Thank you!

• Yes, I've searched similar issues on GitHub and didn't find any.

Which version contains the bug?

3.0.0

Describe the bug

Hi,
Perhaps the problem with Grafana v11.3.0 can also be solved by modifying the module.
I don't know who exactly is responsible for fixing the problem, because i don't know exactly where the problem is caused and who can fix it best
I will also pass on the other tickets here:

grafana/grafana#95408
grafana/grafana-image-renderer#582
Mikesch-mp/icingaweb2-module-grafana#344

The problem is the seems to be the panal id. With 11.3.0 the variable for the panal id changed:

v11.2.2
https://XXX/d/icinga2/icinga2-with-influxdb?var-hostname=XXX&var-service=Load%201h&var-command=load&from=now-3h&to=now&orgId=1&viewPanel=3

Here it is &viewPanel=3

v11.3.0
https://XXX/d/icinga2/icinga2-with-influxdb?var-hostname=XXX&var-service=Load%201h&var-command=load&from=now-3h&to=now&orgId=1&viewPanel=panel-3&timezone=browser&var-disk=$__all&var-threadcount=$__all

Here it is &viewPanel=panel-3.

Futhermore automatically "&timezone=browser&var-disk=$__all&var-threadcount=$__all" is added for variable without a definition ($__all).
In 11.2.2 they are not added automatically to the URL

##################
As you can see, it is an Icinga2 implementation. The url is build by Icinga2, concretely the Icinga2 grafana plugin. I think there is a discrepancy between the Icinga2 module and the Grafana panal id variable, which has changed in 11.3.0.
Possibly also in interaction with the image renderer plugin.
I use this environment:

Icinga2 2.14.3
Grafana Plugin v2.0.3 - https://github.com/Mikesch-mp/icingaweb2-module-grafana
same Problem with v3.0.0 - https://github.com/NETWAYS/icingaweb2-module-grafana

Grafana 11.3.2 ( But also with v11.3.0 ). With v11.2.2 it works.
grafana-image-renderer v3.11.6

I hope this will help.
I will also add this comment to other Github tickets.

How to recreate the bug?

Rendering a Grafana Dashboard via a Icinga2 check.

Hi, thanks for the detailed info. I'll have a look at it.

Hi, thanks for the detailed info. I'll have a look at it.

Thank you.
Maybe it had also something to do with $__all.
I see today, that the graph is rendered from a check, which fill out a variable and not there where the variable is not transmitted by the grafana module:

That works ( disk check with the mount point /home (&var-disk=%2Fhome&var-threadcount=$__all) ):
https://XXX/d/icinga2/icinga2-with-influxdb?var-hostname=XXX&var-service=Disk%20Space%20%2Fhome&var-command=disk&var-disk=%2Fhome&from=now-7d&to=now&orgId=1&viewPanel=panel-8&timezone=browser&var-threadcount=$__all

This don't work (&var-disk=$__all&var-threadcount=$__all)
https://XXX/d/icinga2/icinga2-with-influxdb?var-hostname=XXX&var-service=Memory&var-command=mem&from=now-3h&to=now&orgId=1&viewPanel=panel-13&timezone=browser&var-disk=$__all&var-threadcount=$__all

When i open the URL directly in the browser, it works for both:

Is there any progress on using the Plugin with Grafana 11.3 Versions?
With v11.2 everything works fine, but there are massive problems (timeout in proxy mode, broken graphs, etc.).
Im currently locked my Graphana Version, but it would be nice if this will work with current Version.

Thanks!

Hi,
We are aware of the problems and will likely work on them in due time.
At this point, I am not afraid to add a reminder, that sadly we have to earn money to pay rent and such trivialities, a necessity to which this piece of software is not a direct contributor.
Therefore the priorities are not favouring this very project.

I have to ask to you for some patience in the mean time :-)

Hi y'all,

I need some feedback on this issue.

I've not been able to recreate this issue. I'm currently running Grafana 11.5 with Image Renderer 3.12.4.
InfluxDB as a backend.

Can someone describe the exact steps to recreate this error?

I tried to follow this to recreate the issue: grafana/grafana-image-renderer#582 (comment)

While I did see an error once, it wasn't consistent.
