Real-Time Expert
The Real-Time Expert enables you to get both an expert opinion as to what, if
any, problems there are on your network, and to create “what-if” scenarios
about the effects of various changes to your network, based on your actual
network data.
The Real-Time Expert is a “for charge” upgrade to Observer. Visit our
Web site at www.networkinstruments.com for more information. You
may also call your Network Instruments’ distributor or call your Network
Instruments’ sales representative. In the Americas, Middle East areas,
and Australia, telephone our U.S. office at 1-952-932-9899 or email us
at [email protected]. From other areas, contact our U.K.
office at +44 (0) 1959 569880 or email us at
[email protected].
From the Packet Capture viewer, click on the Expert Analysis tab. The
Summary display contains a list of error conditions found and an Expert
Analysis pane containing a summary of Real-Time Expert’s conclusions about
the problems and possible causes (in the case of a well-functioning network
with few errors, the findings will be brief).
