Activate Network Mapper

Prerequisite

After you have configured and registered your Broker VM, you can choose to activate the Network Mapper application.

The Network Mapper allows you to scan your network to detect and identify unmanaged hosts in your environment according to defined IP address ranges. The Network Mapper configurations are used to locate unmanaged assets that appear in the Assets table. For more information, see All assets.

1. Select Settings → Configurations → Data Broker → Broker VMs.
2. Do one of the following:

   • On the Brokers tab, find the Broker VM, and in the APPS column, left-click Add → Network Mapper.
