With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
cDhcpv4ServerSubnetFreeAddrLowThreshold
Cisco Dynamic Host Configuration protocol Server Subnet Free Address Low Threshold
1.3.6.1.4.1.9.10.102.1.4.2.1.4
The low threshold for available free addresses in this subnet. If the value for available free addresses in this subnet becomes equal to or less than this value, a cDhcpv4ServerSubnetFreeAddrLowThreshold event will be generated for this shared network. No more cDhcpv4ServerSubnetFreeAddrLowThreshold events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses has exceeded the value of cDhcpv4ServerSubnetFreeAddrHighThreshold.
