1590.0. "Different PA inacuracy" by JETSAM::WOODCOCK () Thu Oct 03 1991 13:12

Hello,

I have noticed a different inacuracy with the PA module which most likely
needs attention for v1.2 if not already fixed. An example would be if you
request past statistics for an interval; and the polling failed during the 
START time frame, PA can produce exceedingly high stats. What lead to this 
finding was that I asked for stats from 8am to 5pm as a single duration.

show node4 xxxx circuit yyy all statis,for start 8:0 every 9:0 until 17:0 -
dur 9:0,in domain zzz

The stats showed utilization of 140%.

I then requested counters for the same time frame and what was returned was
a counter from the night before, then counters from about 10am up to 5pm.
The counters were missing because the historian process had stopped. But I
would think PA should better recognize the situation and respond with an
appropriate error.

best regards,
brad...

For anyone interested:

I'm glad to say this turned out to be a user problem and not a PA issue.
There were enough counters for PA to operate correctly for the scope of
time. The missing counters were just before the SOT and it just proved to
be a misleading clue. Anwar's fine math skills showed us to have ~89kbs
on the circuit for the interval. Our records showed us to have a 56k
circuit, line speed was set to 56k, and our internal vendor verified their
records for providing us with 56k. WRONG. After a little investigating it was
proven to be a 128k. When was the last time you got more bandwidth than
you thought you had :-). Good stuff cheap.

best regards,
