Description
Capturing and Mining Data
When Adaptive capture is enabled, Sniffer Adaptive
Application Analyzer generates Adaptive Session Packets for
all protocols with an ASI Protocol Interpreter. You use the
Adaptive Packet Slice Size option to specify how much of
each packet without an ASI protocol interpreter Sniffer
Adaptive Application Analyzer should capture.
There are two classes of packets without an ASI Protocol
Interpreter:
• Standard IPv4 Protocols on Well-Known TCP/UDP
Ports
Sniffer Adaptive Application Analyzer still records generic
session metadata for these protocols, either listing them
using hardcoded aliases or identifying them as GENERIC
(refer to Session View for GENERIC Protocols on page 150
for details.
• Others (Non-IPv4)
Sniffer Adaptive Application Analyzer does not record any
session metadata for these packets.
Refer to Protocols Supported for Sniffer Adaptive Processing
on page 18 for a list of protocols with ASI protocol
interpreters.
When Raw capture is enabled, you use the Raw Packet
Slice Size option to specify how much of each packet to
capture.
Once you have finished configuring the capture session, start capture
with either the Start Capture button in the toolbar or the Quick
Select > Start Capture menu item.
Once you start capturing packets, the Availability Meter at the base of
the Graph panel changes from Yellow to Green (Figure 5-3), indicating
that both packet data (adaptive or raw) and monitoring statistics are
available. You can view statistics in the Statistics panel, as well as mine
this portion of the stream for packets. Refer to Availability Meter on page
56 for details.
