Data Collectio in a Two-Tier Deployment

The NFA console and Harvester components work together in the following way on a 2-tier architecture deployment:

New Harvester

Distills the raw flows from the routers, parses the data, and compiles historical (15-minute) data and 1-minute data. The Harvester stores the following data:

• Raw flow data
• 1-minute resolution data
• Historical (15-minute) data

Note: It is important for the Harvester server to have adequate storage space, as it stores more types of data than on a three-tier architecture deployment.

NFA console

Gathers data from the Harvester as needed and displays report data in the web interface. Stores Enterprise Overview data.

Supplies a web-based user interface for administrative tasks and reports and stores the Enterprise Overview data. Reports consist of the following data:

• Enterprise Overview data that is stored locally
• 1-minute data and 15-minute data that is stored on the Harvester
