HP ProCurve 6400cl Series Management And Configuration Manual page 453

Example of Event Counter Operation. Suppose the switch detects the
following after a reboot:
■ Three duplicate instances of the PIM "Send error" during the first log
throttle period for this event
Five more instances of the same Send error during the second log throttle
■
period for this event
Four instances of the same Send error during the third log throttle period
■
for this event
In this case, the duplicate message would appear three times in the Event Log
(once for each log throttle period for the event being described), and the
Duplicate Message Counter would increment as shown in table C-3. (The same
operation would apply for messages sent to any configured SNMP trap receiv­
ers.)

*This value always comprises the first instance of the duplicate
message in the current log throttle period plus all previous occurrences
of the duplicate message occurring since the switch last rebooted.
