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).
