Required User Role: Organizational user with appropriate permissions. For more information, see User Roles.

If you experience issues with an active scan, Tenable Support may ask you to run a diagnostic scan to assist with troubleshooting. After Tenable Security Center runs the diagnostic scan, download the diagnostic file and send it to Tenable Support.

Before you begin:

  • Add an active scan, as described in Add an Active Scan.
  • Confirm the scanner associated with the active scan is running a supported version of Tenable Nessus. For minimum Tenable Nessus scanner version requirements, see the Tenable Security Center Release Notes for your version.

To run a diagnostic scan:

  1. Click Scans > Active Scans.

  2. In the row for the scan where you want to run a diagnostic scan, click the actions menu.

    The actions menu appears.

  3. Click Run Diagnostic Scan.

    Note: You must resolve repository errors before running a diagnostic scan.

  4. In the Diagnostic Target box, type a target as a single IPv4 address, IPv6 address, or hostname. The target must also be specified in the active scan's Targets.

  5. In the Diagnostic Password box, type a password to secure the diagnostic file.

  6. Click Submit.

    The diagnostic scan runs and finishes.

  7. Click Scans > Scan Results.
  8. Locate the diagnostic scan and confirm that the scan finished without errors.
