Global Agent Settings

The following table describes the global agent settings you can configure in Tenable Nessus Manager:

Option Description
Manage Agents

Track unlinked agents

When this setting is enabled, agents that are unlinked without manual intervention (due to an inactivity timeout) are preserved in the manager along with the corresponding agent data. This option can also be set using the nessuscli utility.

Note: This option does not allow the manager to track deleted agents. When you delete an agent, the manager and/or cluster no longer tracks or recognizes the agent.

Unlink inactive agents after X days

Specifies the number of days an agent can be inactive before the manager unlinks the agent.

Inactive agents that were automatically unlinked by Tenable Nessus Manager automatically relink if they come back online.

Requires that Track unlinked agents is enabled.

Remove agents that have been inactive for X days

Specifies the number of days an agent can be inactive before the manager removes the agent.

Remove bad agents

When this setting is enabled, agents with one or more of the following criteria are removed from Tenable Nessus Manager:

  • The agent was previously deleted or removed by a user.

  • The agent does not provide a valid access token.

  • The agent was blocklisted.
