Sniffer Adaptive Application Analyzer: Adaptive Mode ... - NetScout

EARLY FIELD TRIAL Chapter 4
96 Sniffer Adaptive Application Analyzer
The new Top N setting will take effect the next time the Statistics panel
refreshes, either automatically or in response to the Refresh button. It
will remain in effect until you close the stream or change the value again.
Note, however, that the next time you open this stream, it will use the
default Top N value specified in the Quick Select > Options > General
tab. To change the Top N value permanently, you must change the
setting in the General tab.
Tabs Affected by the Top N Value
The Top N value affects all tabs populated using Conversation records.
This includes the following tabs:
IP Address
Port
Network
Conversation
Advanced
VLAN ID
IP Protocol
IMPORTANT: The Top N feature does not affect the use of RMON
statistics in the Statistics panel’s Summary, Errors, or Destination
tabs. Because of this, when a Top N value is specified, the statistics
shown in the Summary, Errors, and Destination tabs reflect the entire
stream, while the other tabs reflect only a subset of the total data seen
on the stream.
Top N – The Details
The Top N feature does not result in the display of exactly the number
of conversation records specified for N. Instead, it results in the display
of approximately N number of conversation records from each bucket
of conversation records required to represent the current Graph
panel time selection.
This will almost always be an approximate multiple of N depending on
the number of buckets required to represent the current time selection
and the number of records in those buckets.
