2833.0. "exporting statistics?" by CLARID::HOFSTEE (Take a RISC, buy a VAX) Thu Apr 23 1992 11:18
I have some questions on the way the exporter works when exporting statistics.
I understand that when you export data with an export period of let's say
20 minutes , the exporter exports ALL attributes for the entity. Let's
assume we have an SNMP entity for which I export data with an export
period of 20 minutes and that I start this operation at 9:10.
Then normally I would expect data to be available at 9:10,9:30,9:50. But how does
this work for the exported statistics? I seem to remember that the default
duration for statistics calculations is 1 minute.
My questions are :
1. Does that mean that the
exported statistics are available at the same moments as mentioned above
and calculated over the last minute of each interval (9:09-9:10,9:29-9:30 etc)
or will this data be available one minute later and calculated over
(9:10-9:11,9:30-9:31) .
2. How can I change the default duration that the exporter uses for the
statistics.
3. What happens if this duration is greater than the export period? So let's
say you have an export period of 20 minutes and a duration of 1 hour.
Is this possible and when will the exporter export the statistics and
over what time period are they calculated?
will it execute an export command at 9:10,9:30 etc, and the results be
available at 10:10,10:30
Thanks

where delta is a delay which depends on the response time
from Show commands and the system load.
If we assume that the system is not busy and the response time = 0
than the delay = 30 sec.
So if you specify export period = 20 min duration will be 19 min 30 sec.

| 2833.2 | some clarification | CLARID::HOFSTEE | Take a RISC, buy a VAX | Fri Apr 24 1992 05:33 | 20 |
|
Let's see if I understand you correctly:
1. The DURATION to calculate statistics is always (almost) the same as the
export period.
2. Suppose I see in my RDB file the following values: (Export period 00:10:00)
in_packets
9:10 200
9:20 300
9:30 100
It means that the polled IP system received 300 packets between 9:10 and 9:20
