You could set up your dhcpd to maintain PF tables (see dhcpd's -A -C
and -L options) and monitor the number of entries in the tables. You
could even use something like pfctl -t assigned -T show | wc -l

I've used this before with good results:

Would I be better off using a different dhcpd?

Monitoring DHCP pool state

[Ian Chard]

Hi,

I'm using the stock OpenBSD dhcpd, and I'd like to monitor the state of 
the pool (how many addresses in use/available).  Is there any way of 
doing this without writing a parser for /var/db/dhcpd.leases?  Would I 
be better off using a different dhcpd?


Thanks
- Ian
