I am trying to monitor ISC DHCP server with version 2. It wants a pool name. I have been unable to find how to name a pool in dhcpd.conf or what exactly it wants for that pool name. Could someone point me in the right direction on getting a DHCP server monitored on an Ubuntu box. I used to do it with the isc_dhcpd plugin but that fails with Python3. Any help would be greatly appreciated. Thanks in advance.

Hi @gcstech
I don’t know how you can “name” a pool in dhcpd.conf, but if you don’t, it’s apparently called as its range. There is also a tool called dhcpd-pools (which isn’t installed per default), that can gather the information about configured pools in dhcpd.conf.
I just tried that out with a CEE 2.0.0 (no, haven’t applied p1 yet…) and the shipped isc_dhcpd.py plugin that requires Python 3. The agent is running on a RPi together with the plugin, and upon discovery the pool was automatically named as the range it serves with a dash between the first and the last address, see here:
If I would want to create a rule for this particular pool now, I’d have to use it as follows in the
pool name field of the corresponding rule: 192\.168\.1\.100-192\.168\.1\.120$
At least this is what CMK did, when I clicked on “Edit and analyze the check parameters of this service” and then on “Create Pool name specific rule for”.
HTH,

Thomas,
Thank you, your answer got me to what I needed. I just needed the plugin. Once installed it picked up the three pools and is monitoring free leases.
