 problem with onstat -p "pagreads" value decrementing
Hi,

Has anyone noticed a problem with the pagreads stat in onstat -p being
decremented in what looks like a random way?

I parse the output of onstat -p regularly and store the output into a csv
file.  I've noticed that after an unpredictable amount of time the value
gets decremented by 2 million !!!  Isn't this a cumulative stat?

Since I gather this information regularly, I have only been zeroing out my
stats once a week.  I'm going to try to do this daily and see if this makes
any difference.

I'm on IDS 7.30 UC7

2 million or 2 billion?  You may be seeing the counter roll over.

cheers

I assure you that the counter is not rolling over.

I'm seeing the counter go from (1 example) 5602893 to 3536618 and then the
number gradually climbs as you'd expect it to...

  onstat -z resets the counter to 0.

I'm resetting the stats daily now.

On Friday, stats were reset at 6:00 am.

by 3:27pm the pagreads value had reached 7190253
at 3:28pm the pagreads value was  5122344

again,

by 7:03pm pagreads had reached 6044502
at 7:04pm pagreads was now 3985017

This seems really bizzarre to me...

Ben
