Disabling analysis on the lower layer will disable analysis on all
upper layers.This enables you to focus on specific network
problems precisely.
Specify the maximum number of objects that can be created
in the database for each Expert layer. To reduce the amount of
memory needed to create network objects, you can specify the
maximum number of objects that the Expert can create for each
Expert layer. Double-click in the Max Objects column of the
Objects tab to specify the maximum number of objects that can be
created in the database for each Expert layer.
NOTE: To help with configuration, the Expert shows the
estimated amount of memory needed for the number of
objects selected for each layer in the Est. Memory column of
the Objects tab.
Specify whether to recycle Expert objects (the default) or
stop creating new objects when there is no more room in the
database. The Expert builds a database of network objects from
the information in the packets accumulated in the capture buffer.
Because some networks can be immensely complex in their
structure, at some point the Expert will have no more memory for
new network objects. If you recycle objects, the Expert continues
to add new objects to the database, overwriting the least
interesting objects when it runs out of memory (objects with no
associated errors are considered “least interesting”). If you do not
recycle objects, the Expert stops creating new objects when it runs
out of memory, and instead, continues to interpret traffic in
accordance with the information it has already stored in its
database.
Enable/disable real-time Expert analysis during capture. By
default, when you start a capture, the Expert analyzes the packets
coming into the buffer and displays the results in real time in the
Expert window. You can observe the network objects, symptoms,
and diagnoses that the Expert analyzer creates while the capture
progresses. You can disable real-time Expert analysis if you prefer.
Specify the maximum number of alarms that can be created
in the Expert database. When the maximum number is reached,
the Expert will either recycle the oldest and lowest priority alarms
(if the Recycle Alarms option is selected) or stop creating new
alarms.
This Recycle Alarms option specifies what the Expert does when
it runs out of memory:
