Counters
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
MAC Statistics window
is in Capture mode, you can use all three types of counters. When the MAC Statistics
window is in Transmit mode, custom counters are not relevant and do not appear in
the
MAC Statistics 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
Packet counters count the number of packets/bytes received or transmitted. Packet
counters are viewed from the
MAC Statistics window.

ing/capturing or transmitting data.
