Using Real-Time Expert
 283
If the amount of RAM available for the Observer buffer is not large or is not large enough 
to capture the event in question or for the amount of time required to view the conditions 
in question, you should set Observer to capture using a circular buffer. In this case, 
Observer will capture packets until the buffer is full and then add new packets to the buffer 
while removing the oldest packets. As this process continues, the Expert Summary and 
Expert Events sections will continue to collect totals for events.
After some period of time, the Expert Events dialogs begin to remove non-
critical events based on the user-supplied settings in the General tab under 
Expert Global Settings.
Post-Capture Analysis
Post-capture analysis can be done on an Observer capture buffer or Sniffer
®
 buffer. Often 
a capture from a remote site will be forwarded to an individual with Real-Time Expert for 
analysis. Post capture Expert Analysis does not have any of the buffer limitations of real-
time analysis.
