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:

	Table 12-1. MAC Layer Counter Types
Counter Type	Description
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.

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.
