Sniffer Adaptive Application Analyzer Overview
The following table defines terms and concepts used in this manual.
Adaptive Session Intelligence is a Sniffer technology used to streamline
network analysis by extracting key fields from supported protocols and
preserving them in a .asp trace file. The .asp trace file is associated with
a corresponding .asr trace file where correlated session level metadata is
stored.
Adaptive Session Intelligence (ASI) Protocol Interpreters condense raw
packets into Adaptive Session Packets. For supported protocols, ASI
Protocol Interpreters extract key fields and generate Adaptive Session
Packets with derived payloads. Other protocols can be captured with the
raw payload intact or with an optional slice size.
Condensed “packet events” generated by ASI Protocol Interpreters for
supported protocols. ASPs consists of compressed headers through Layer
4 along with key fields extracted from the application payload.
Adaptive Session Records store session-level metadata for transactions
observed using supported protocols – for example, an HTTP session, an
email exchange, and so on. Adaptive Session Records let you view
combined statistics for entire sessions not available in a single packet.
Adaptive Session Records are stored in .asr files and are associated with
corresponding .asp files. You can drill between separate decode views for
each to see both top-level session statistics and the packet-level details.
Network capture with Adaptive payload generation enabled (the default).
You can also use traditional packet capture; refer to Using Traditional
Packet Capture.
