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
5.0 response 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 3-10 shows 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.
Figure 3-10 NAM Application Response Time Measurements
Figure 3-11 shows a representation of total transaction time as opposed to application response time.
