Please only include addresses in your network, as each address undergoes in-depth processing.
The Monitoring page appears. Once NNM starts monitoring traffic, the page displays various high-level charts about the vulnerabilities, assets, connections, and bandwidth usage that NNM has detected, as well as real-time events that NNM has triggered.
