Cannot view all chart panels in the dashboard


If users cannot view all chart panels in the Certificate Manager dashboard in Tanium Reporting, the user permissions might not have sufficient permissions.


In addition to the Certificate Manager roles, users must also have sufficient management rights, such as All Computers.

For more information about Certificate Manager roles, see Set up Certificate Manager users.

Unexpected certificate audit results


If an endpoint shows the following error in the Protocol column, you might have to refresh a certificate audit on that endpoint: Error: Protocol and cipher suites do not exist. Run the Certificate Audit package.

Certificate audit status shows Failed for some endpoints.


  1. Verify that a certificate audit completed successfully.
  2. If the States of machines section shows any Failed statuses, click Show Client Status Details.
  3. Select one or more endpoints that show a Failed action status and click Get action log for selected machines.
  4. Review the action log to determine the cause of the failure.

Error: EC_KEY_new_by_curve_name


Older Linux endpoints with OpenSSL versions earlier than 1.0.1 cannot successfully run the Deploy Certificate Audit [Non-Windows] package. The following error is found in the action log: undefined symbol: EC_KEY_new_by_curve_name


Upgrade to OpenSSL 1.0.1 or later.

ERROR - lsof was not found


To include the owning process data for Linux endpoints, the lsof command is required. If a Linux endpoint does not have lsof installed, the following errors are found:

  • from the Certificate Manager - Coverage Status Details sensor: Missing lsof command

Use either of the following options to confirm the error and then install lsof.

    1. From the Main menu, go to Modules > Certificate Manager > Overview.
    2. In the Certificate Manager Endpoint Coverage chart of the Overview section, click Needs Attention.
  2. Check the action log for the Deploy Certificate Audit [Non-Windows] action. For more information about how to view the action log, see Tanium Console User Guide: Investigate action-related issues.

  2. Select the check box in the Certificate Manager section, and then click Uninstall and follow the process.
