Log Record counter information. Surveyor enables you to capture all byte, frame,
and error counter values compiled during the capture or transmission of data.
Monitor Real-time views for data seen on a network segment. The data can be
viewed in numerous ways and from different perspectives. Display of the
data can be either graphical charts or row-and-column tables.
Settings Alarms Alarms can be set to flag network conditions. Actions can be performed
when alarms are triggered.

Function Description
Remote Functions
(Remote plug-in) All data collection and data management functions described in Table 1-1
are available from other devices in a distributed network.
Transmit
(Packet Blaster
plug-in) Send data to a network. Surveyor lets you see what happens to your network
under precisely controlled conditions. You can play back streams of captured
data or you can transmit edited data. You can edit a stream of captured data
by changing the sequence of the packets, deleting or adding (inserting) pack-
ets, creating bad packets, eliminating all packets of a certain type (protocol)
and so on. Surveyor also gives you complete control of when, how fast, how
long, and how often it transmits the data you want to send over the network.
Expert Analysis
(Expert plug-in) Expert analysis starts with the automatic logging of possible problems.
Expert data views display counters, addresses, protocols, and diagnostic
information related to the detected network condition. Expert alarms can be
set to flag network error conditions. Actions can be performed when alarms
are triggered.
Voice/Video over
Ethernet Analysis
(Multi-QoS plug-in) Decode VoIP and other synchronous protocols in an Ethernet environment
and present the data in tables.
Multi-QoS data views display counters, call
detail records showing QoS statistics, addresses, and protocol conditions
related to conversations and channels within the H.323, SIP, or Cisco’s
SCCP protocol.
