Figure 9-7. Alarm Example, MAC Errors
This example shows an alarm group consisting of five MAC Layer alarms: Errors
(two alarms), Oversize Frames, CRC/Alignment, and Fragments. Each of these
alarm counters are checked at five-second intervals. When an alarm threshold for
any of these five alarms is exceeded, Surveyor issues an audible alarm and displays
a message in Surveyor’s message window.
Assume that overall error rate is of particular interest in this example. The Severity
setting instructs Surveyor to include a Warning message with all alarm messages
when the error rate is greater than 250. The Actions setting instructs Surveyor to
send an e-mail message whenever the rising value (threshold) for the overall error
rate exceeds 250.
