Passive measurement

Passive measurement involves observing and collecting data without actively interfering or sending signals to the system being monitored. It’s like standing back and silently watching a process to understand how it works, rather than asking it questions or making changes. This approach allows for the collection of natural, real-world information about performance, behavior, or conditions, providing insights without affecting the system’s normal operation. Passive measurement is commonly used in network monitoring, environmental sensing, and performance analysis to gather accurate data while minimizing disruption.
