If you use for example Nagios, dhcpd-pools has built in support for that.
Example of a Nagios/nrpe check definition in the nrpe.cfg is below. You can of course script the schedule and alerting without Nagios.
command[check_dhcp_pools]=/usr/bin/dhcpd-pools --warning 90 --critical=95

Dhcpd-pools is on-demand info.
I would like dhcpd to inform me by it self.
