Cloud Settings Section

The Cloud Settings section provides options for configuring Tenable Nessus Network Monitor to communicate with Tenable Vulnerability Management.

Note: Tenable Nessus Network Monitor processes a large amount of data. When you connect to Tenable Vulnerability Management, use multiple Tenable Nessus Network Monitor scanners to filter the data. If your Tenable Nessus Network Monitor is managed by Tenable Vulnerability Management, each Tenable Nessus Network Monitor report file can have a maximum of 5000 hosts or 1 GB of data.

If your report file exceeds the maximum size or number of hosts, the next time you log in to Tenable Nessus Network Monitor, a warning appears indicating that the results of the last file uploaded to Tenable Vulnerability Management were truncated. A similar warning appears in Tenable Vulnerability Management, in the Tenable Nessus Network Monitor scan details.

You can adjust your monitored ranges to prevent truncated results in Tenable Vulnerability Management. For example, if you want to monitor 50 networks, you can use two Tenable Nessus Network Monitor scanners covering 25 networks each.

These limits apply only to Tenable Nessus Network Monitor instances managed by Tenable Vulnerability Management.
