Hi! Could you please check what version of Grafana do you use? Quick googling shows me Systemd: Upgrading from 8.0.6 to 8.2.0 broke grafana · Issue #40162 · grafana/grafana but it was actual for Grafana 8.2.0 and already fixed. Also I have nothing similar in Logs on my Plesk (but I use different OS). And one more question, in Plesk, when you open Monitoring, does it show Grafana graphs?

 

[ivanes82]

The installed version is grafana 10.1.5. Monitoring works as expected. These warnings only appear when the service is started. I have not modified anything regarding grafana.

Hm... I have performed some tests and also found Unknown lvalue warning on service start · Issue #54772 · grafana/grafana.

This warning typically appears on older versions of systemd. Luckily the systemd developers don't crash the application when it runs into an unrecognized config option. [...] (c) GitHub

I have deployed Plesk on AlmaLinux 8.6 and found the same warnings. After that, I have upgraded AlmaLinux to 8.9...

...and do not see these warning after restarting of the grafana-server.service.


Do you have any system updates available to install on your system? What systemd version is used?
Anyway, it seems it safe to ignore these warnings.

P.S Also was not able to reproduce the issue on AlmaLinux9.3 (with systemd 252).

@tkalfaoglu do you get the same or similar warning? If possible, could you please provide them here?
