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.
