Agent Repositories
Agent repositories can store data from Tenable Nessus Agents (identified by agent ID) or OT Security (identified by OT Security UUID).
An agent ID uniquely identifies agent-detected assets that may share a common IP address.
OT Security assigns UUIDs to assets to uniquely identify them, since not all operational technology assets have IP addresses. Then, Tenable Security Center uses the UUIDs to uniquely identify OT Security data in Tenable Security Center. For more information about viewing OT Security data in Tenable Security Center, see OT Security Instances.

Organizations |

Advanced Settings |

|
Generate Trend Data |
When enabled, Tenable Security Center generates trend data by taking periodic snapshots of the cumulative database. Trend data is displayed in some Tenable Security Center tools (e.g., trending line charts and trending area charts). Tenable Security Center also produces differential data (snapshot comparison data), which improves performance when displaying trend data in Tenable Security Center tools. Tip: Disable this option to reduce your disk space usage. |

Days Trending |
Specifies the number of days of cumulative vulnerability data that you want Tenable Security Center to display in dashboard and report vulnerability trending displays. |
