Overview<br />

Expert Analysis<br />

This section describes how to use the Expert analysis available in the<br />

postcapture analysis window for raw packets. Expert analysis is not<br />

The section includes the following major topics:<br />

Expert Analysis on page 219<br />

Setting Expert Options on page 225<br />

Exporting Expert Data on page 239<br />

The Expert analyzer alerts you to symptoms and diagnoses in network<br />

traffic:<br />

A symptom indicates that a particular traffic element has exceeded<br />

a threshold and may indicate a problem on your network.<br />

A diagnosis can be several symptoms analyzed together, high rates<br />

of recurrence of specific symptoms, or single instances of particular<br />

network events that cause the Expert to conclude that the network<br />

has a real problem. A diagnosis should be investigated<br />

immediately.<br />

The Expert tab shows the results of Expert analysis (symptoms and<br />

diagnoses) in five viewing panes. These panes function together so you<br />

can view and select information on all network levels.<br />
