Monitoring DHCP range

[t3dus]

I've been trying to figure out for a while now how to get Nagios 4 to monitor a DHCP range or at least monitor computers who are using Dynamic IP addresses in a DHCP range.

So far I have only gotten Nagios to monitor servers, computers with static IP addresses.

I believe the historic response to this topic has been "use DNS" where active checks are concerned. If passive checks are an option, then you'd just submit the passive checks via NRDP using the name of whatever Nagios host/service object you'd like to feed results into.

So doing this you wouldn't have a dedicated host file for those clients? Can you elaborate a bit more?

Have you looked into some plugins in the Nagios Exchange for DNS or DHCP?

Were you looking to do active checks or passive checks?
