Response Time

Response Time

The NAM Traffic Analyzer monitors TCP packet flow between client and server, and measures response time data to provide more visibility into application response times (ART) and network latency. NAM

5.0response time monitoring provides end-to-end response times to help you locate possible network and application delays.

Note NAM 5.0 does not support IPv6 for response time monitoring.

You can set up the NAM to measure network time, client response time, server response time, and total transaction time to improve application performance. Figure 3-10shows the various points in network packet flow where the NAM gathers data and the trip times you can monitor. This is one example that represents only a subset of measurements.
