Distribution: official part of Check_MK

Supported Agents: Linux

This check uses the output of "netsh dhcp server show mibinfo" as sent by the Check_MK windows agent when using the appropriate agent plugin. The check uses the values "free", "used" and "pending" leases to monitor the usage of the DHCP pools.

Each DHCP pool will result in one service on the DHCP server.

The check will raise WARNING/CRITICAL states when the thresholds of free addresses are reached. The thresholds need to be given as percentage values.

Item

The name of the DHCP pool as configured on the DHCP server.

Check parameters
