Hi comunnity. On my fresh icinga installation, Grafana module throving following errors:

Deprecated

/usr/share/icingaweb2/modules/grafana/library/Grafana/ProvidedHook/Icingadb/IcingaDbGrapher.php

Hi there,

the Workaround looks like:

I did not try it but I think this repository has the fix integrated:

Hi Moreamazingnick,
thank’s

in this repo, Thema newest version is 2.0.3.
I’m running v2.0.3.
Maybe I have to wait until the next version and pray for support for php8.2

or do you think, they integrated the fix and don’t raise the version number?

Exactly, have a look at the branch summary

and the details

so only one thing changed and it looks like it’s the fix you need.
Also don’t download the released version as this also isn’t containing the fix - you need the get the head or the repository. You can get it by cloning or by downloading this https://github.com/Mikesch-mp/icingaweb2-module-grafana/archive/refs/heads/master.zip

Hi, anyone here who tested this fix and has positive experiences? I added the line “#[\AllowDynamicProperties]” into HostDetailExtension.php and ServiceDetailExtension.php and the results are: “deprecated”-message disappear but no graph is rendered inside icingaweb2 (stays empty). If you change directly to grafana by clicking on the graph data will be displayed.
