Surveyor provides sophisticated counters to enable you to precisely monitor 
network activity. Surveyor features three types of counters at the MAC layer: Packet 
Counters, Custom Counters, and Error Counters. When the 

 window 

is in Capture mode, you can use all three types of counters. When the 

 

window is in Transmit mode, custom counters are not relevant and do not appear in 
the 

 window. 

Surveyor provides three types of MAC layer counters:

Surveyor provides counters of expert events with the Expert plug-in. Surveyor also 
provides counters of H.323 with the Multi-QoS plug-in.

Log files contain snapshots of Surveyor counter information. All byte, frame, and 
error counter values are recorded in the log file. Refer to the section on Logging for 
more information. 

Packet counters count the number of packets/bytes received or transmitted. Packet 
counters are viewed from the 

 window. 

Packet Counters

Count the number and type of packets and bytes captured or transmit-
ted by the Surveyor.

Custom Counters

User-defined counters used to control data capture activities while the 
Surveyor is in capture mode.

Error Counters

Count the number of errors that occur while the Surveyor is monitor-
ing/capturing or transmitting data.
