@pony @valleyforge nagios but with only ping and ssh checks
@pony @valleyforge also icinga2 is the better nagios
@pony @valleyforge tbh I don't know if nagios has newer versiona that are good, but you could like test icinga2 and see if you like it.
When I'm home I can show you some examples of configuration, and screenshota and stuff, if you want.
@pony @valleyforge I've only seen ages old nagios at previous job.
@pony @valleyforge well if there's.no agent running on a thing, you can only check stuff like ping, arp, are the ports that are supposed to be open open, etc. So ssh for linux thinga and idk rdp? for windows.
You could also run some agent on hypervisors and export VM data from there, at least stuff like cpu usage should be available.
Also, for physical servers you could check power status and sensors via IPMI.
@pony @valleyforge Also instead of nagios/icinga you coyld use sth more trendy like prometheus
@pony @valleyforge the advantage to that wouls be easier to find existing maintained plugins/integrations, the disadvantage is that it's trendy
