I am trying to monitor how many IPs we are currently using and how many we have remaining (percentage or integer). I am following these instructions: https://www.paessler.com/knowledgebase/en/topic/11433-how-to-monitor-windows-dhcp-scope-release However, I tried importing the DHCP MIBs form out DHCP server, then added the sensors through the SNMP Library. I am able to add them and they show green, which is correct for now, but they always return a value between 0 and 1. This isn't very useful to me, since I can't see how close we are to using all of our IP addresses. I had tried the method in the address above, before importing the MIBs, but it wouldn't work at all and just returned an SNMP error no such name. Any help you can offer would be appreciated.

Thanks,

Logan

Hello,

thank you very much for your KB-Post. The MIB in the linked article seems to be a Microsoft specific MIB. Is this a Windows Server here, serving as DHCP Server (as well)?

best regards.

I figured it out. I had to changed the OID type from delta to gauge. The sensors then started returning the exact number of IP addresses in use and free.
