Log Throttle Periods; Example Of Event Counter Operation - HP PROCURVE 2520 Management And Configuration Manual

Log Throttle Periods

The length of the log throttle period differs according to an event's severity
level:
Severity Level Log Throttle Period
I (Information) 6000 Seconds
W (Warning) 600 Seconds
D (Debug) 60 Seconds
M (Major) 6 Seconds

Example of Event Counter Operation

Suppose the switch detects the following after a reboot:
■ Three duplicate instances of a "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-2. (The same
operation would apply for messages sent to any configured SNMP trap
receivers.)

*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.
