Monitoring DHCP Service
You’ll need to monitor DHCP service. There are two main ways to monitor DHCP
service. First, you can view the client list; second, you can monitor the log files
generated by the service. You can use the service logs to help troubleshoot network
problems. The following sections discuss these aspects of monitoring DHCP service.
Viewing the DHCP Status Overview
The status overview shows a simple summary of the DHCP service. It shows whether or
not the service is running, how many clients it has, and when service was started. It
also shows how many IP addresses are statically assigned from your subnets and the
last time the client database was updated.
To see the overview:
1 In Server Admin, choose DHCP from the Computers & Services list.
2 Click the Overview button.
