I've been testing STATISTICS partitions for different entities in an
effort to find a means of detecting a broadcast storm. To get all of
the alarm rule syntax squared away, I have been "testing" the following
alarm rule expression:
(BRIDGE .bridge.DECBG1 LINE 2 count of total frames received >=20000,-
FOR EVERY 00:00:30 UNTIL 00:05:00 DURATION 00:00:20)
When enabled, an exception results:
OSI Rule Exception
Event Type |QualityofServiceAlarm
...
Additional Info
significance |True
information |Software logic error detected
significance |True
...
Perceived Severity |Indeterminate
_____
Did I misunderstand the scope of interest time syntax? My goal is to
gather statistics EVERY 30 seconds for a DURATION of 20 seconds and
alarm on any COUNT OF TOTAL FRAMES RECEIVED >=20000.
The documentation states that eliminating the UNTIL qualifier will
cause the alarm rule to continue evaluating until Ctrl-C is pressed.
This is what I really want, but it doesn't work. Neither does this.
What gives?

Maybe this will help understand time and stats. Statistics uses a scope of intrest time to base it calculations. To repeat it a schedule time is required. in a show context it is show entity foo all statistics - at every 00:00:30 for start=now dura=0:00:20 | |||||

That makes perfect sense. The documentation is vague on this. I did
not see such an easily understood explanation (which I will test
tomorrow) in the docs.
Some additional work must be done to illustrate this in the docs.
Multiple examples would be nice.

| 4112.3 | Scope of Interest Time limited to 1 minute | CUJO::HILL | Dan Hill-Net.Mgt.-Customer Resident | Fri Nov 20 1992 01:39 | 5 |
Well, I finally found it in the PA documentation. Seems that you are
limited to a duration of 1 minute. This should be fixed in a future
release. We need finer resolution.
