RE: ISC-DHCP server number of active leases
Hi Dan / list,
>> I am running multiple isc-dhcp servers on Debian Linux.

>> However, in some networks I KNOW I regularly hand out far more then 50% of the assigned ip numbers and I have set the default and max-lease-time low enough to free up ip numbers asap.
>> So far so good, I have had no problems this year but... we are growing and people have more mobile devices so I want to know HOW CLOSE I am to running out of free dhcp leases.

That seems to do a lot of what I want, however our current monitoring tool can do stuff a lot easier if it were accessible via SNMP.
It seems there is a tool that can help https://github.com/ohitz/dhcpd-snmp
It is a perl script that I somehow need to hook into the net-snmp tool. Has anyone even done this on a Debian machine, I have not used SNMP on a Debian machine before and have yet to read all the documentation as to how I can install a perl script as an extention. Anyone who can help, please do so. What do I need to focus on at first?
