How the Network Performance Advisor
Collects Data
If you have data collection enabled in the Settings - Top Tools Services page,
the Data Collector begins automatically when you start your PC. The historical
traffic data is written to disk once per hour. It reflects activity on the network
during the past hour.
Understanding HP Sampling
The Network Performance Advisor analyzes network traffic data over time,
allowing the Advisor to detect long-term trends and problems on the network.
When you run a report, recommendations are made that will improve your
network performance.
