My Nagios Core server is an Ubuntu 20.04 LTS device, I installed pnp4nagios plugins and it works well, the graphs are displaying on the "http://@IP/pnp4nagios/" page.
However, I'm trying to put the graph icons on Nagios Core (in the Services menu) but echatspin echatrandom I don't know how to do it.
So please, I need your help.
