Data Collection in a Three-Tier Deployment

The NFA console, Harvester, and DSA components work together in the following way on a 3-tier architecture deployment:

Harvester

Distills the raw flows from the routers, parses the data, and records it.

Stores the 1-minute resolution data and the raw flow data. Raw flow data is stored for the previous 24 hours.

NFA console

Gathers the Enterprise Overview and 15-minute (historical) data from the Harvester and aggregates the 15-minute data.

Stores the Enterprise Overview data.

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

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

DSA

Collects the 15-minute resolution (historical) data from the NFA console and stores it.
