Surveyor
User’s Guide
Surveyor's user interface provides both a comprehensive view of the network as
well as the ability to easily drill down to a specific network segment. Surveyor's
main window provides a single, user-defined view for each of the segments being
monitored. The user determines what information to view for each segment such as
network utilization, protocol distribution, host table, etc. In this same window, the
user can create alarms that monitor multiple segments simultaneously.
An optional Expert plug-in includes expert features for automatic and very detailed
problem diagnosis. Potential error conditions are automatically logged. Counters,
addresses, protocols, and diagnostic information related to the detected network
condition are displayed. You can also set alarms to be informed of any events
detected by the Expert system.
For test and development environments, an optional Packet Blaster plug-in software
provides advanced traffic generation and intelligent packet and file editing
capabilities.

mation you want to analyze. The data can be viewed in numerous ways and
from different perspectives. Display of the data can be either as graphical
charts or row-and-column tables.
