With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
cDhcpv4ServerSharedNetFreeAddrHighThreshold
Cisco Dynamic Host Configuration protocol Server Shared Net Free Address High Threshold
1.3.6.1.4.1.9.10.102.1.4.1.1.3
The high threshold for available free addresses in this shared network. If a cDhcpv4ServerFreeAddressLow event was generated for this subnet, and the value for available free addresses has exceeded the value of cDhcpv4ServerSubnetFreeAddrHighThreshold, then a cDhcpv4ServerFreeAddressHigh event will be generated. No more cDhcpv4ServerFreeAddressHigh events will be generated for this subnet during this execution of the DHCP server until the value for available free addresses becomes equal to or less than the value of cDhcpv4ServerSubnetFreeAddrLowThreshold.
