DHCP servers should be monitored to ensure that the DHCP service remains available and that the DHCP scopes do not run out of addresses. The maintenance requirements for DHCP servers is minimal, and maintenance is required only when a problem occurs or you need to migrate the DHCP server service to a different computer.
You can monitor the activity on your DHCP server by using the Performance Monitor console. To monitor the DHCP server activity in real time, follow these steps:
Click Start, and then click Server Manager.
In Server Manager, expand Diagnostics\Reliability And Performance\Monitoring Tools\Performance Monitor.
In the Performance Monitor snap-in, click the green plus button on the toolbar.
