I tried yours as well as the one dhcpd-pools
(  There was a night and day
difference.  Yours took 10+ minutes, while the same data set with
dhcpd-pools was done in less than a second.

Kind regards,

This is an announcement of sorts.

I've searched and looked for a tool that lets me monitor DHCP pools,
and possibly get a notification before the pool is full and users
start complaining. But without luck, so I decided to make my own. I'm
making the script publicly available, in case someone else is

The script (written in perl) reads dhcpd.conf and dhcpd.leases, and
will output statistics for each subnet and pool. It can also function
as a Nagios service and Munin plugin. Details on the web page above.

It can possibly be extended to do more.

The script is completely safe and doesn't try to do nasty stuff. Let
me know if you like it and/or have feature requests, patches etc.
