Monitors Windows DHCP servers. Checks usage levels of lease blocks and optionally verifies that assigned devices are listed in Active Directory.
The Windows DHCP Event Monitor checks your DHCP server and warns based on percentages of scope usage and new lease grants. It can also alert you about any devices that have received a DHCP lease but are not listed in Active Directory. This event monitor supports DHCP running on Windows Server 2008 and later. To allow this event monitor to connect, you may need to perform the following steps on the FrameFlow server:
1. Open PowerShell and enter "Add-WindowsFeature RSAT-DHCP".
2. When that completes run "Import-Module DhcpServer".
This event monitor provides the following options:
Use this option to alert if the event monitor cannot connect to the network device.
Use this option to get alerts if the event monitor was able to connect to the device but the DHCP service was not running.
With this option enabled, the event monitor will check each DHCP scope and alert you based on the percentage of assigned IP addresses.
Use this option to get alerts whenever a new lease is granted.
With this option enabled the event monitor will detect newly granted leases and then see if there is a corresponding device in Active Directory. It will alert you if there is no corresponding device.
Enter the distinguished name for the base of the Active Directory search. For example, if you wish to monitor users and computers in the frameflow.local domain, you would enter "DC=frameflow,DC=local".
The account used to monitor this device must be a member of Distributed COM Users group.
This event monitor generates the following data points:
|Available IP Addresses %||The percentage of IP addresses that are available.|
|Available IP Addresses||The number of available IP addresses.|
|In Use IP Addresses %||The percentage of IP addresses that are in use.|
|In Use IP Addresses||The number of IP addresses that are in use.|
