Adaptive Session Analysis
The Adaptive Session View (Figure 7-3) appears when Sniffer Adaptive
Application Analyzer mines data captured in Adaptive mode, providing
end-to-end transaction metrics for TCP/UDP-based sessions.
The mechanics of the Adaptive Session View will be familiar to anyone
accustomed to traditional Sniffer decodes – individual sessions are listed
line-by-line in a Summary pane (a) at the top of the window. Selecting
a session in the Summary pane populates the lower Detail pane (b) with
statistics for the selected session.
Figure 7-3. Adaptive Session View
The actual data presented in the Adaptive Session View is much different
than traditional packet decodes, however. Instead of listing individual
raw packets, the Session View rolls up statistics for entire TCP/UDPbased
sessions between a Client (requesting station) and Server
(responding station). You get true source/destination identification,
along with packet/byte counts broken out by direction. Separate Detail
pane “layers” provide the following information (Figure 7-3):
Overview – A summary of the selected session, including start/
end times, duration, application, and, for protocols with an ASI
protocol interpreter, a short session description (for example, the
URL of an HTTP session).
TCP/UDP Connection Details – TCP/IP statistics for the session,
including endpoint addresses/ports, packet/octet counts in each
direction, and TCP statistics.
