ESALPS uses MONITOR data, that has 100.00% capture ratio, accurate to
the micro second for z/VM. For Linux data, we capture the process table
every minute to correlate to the vm monitor interval. I believe the
capture ratio obtained by ESALPS from monitor data is higher that what
you get from accounting data, but i do measure capture ratio (and have
for 20 years) and it is very very good for monitor data.

The ESAPLPS code that Barton mentioned is doing prorating, right? How
accurate is that? Are you using accounting data or performance data?
I have a long-standing bias against using performance data for accounting
.
I can go into detail, if anyone needs to know, but first we have to see
which data Barton is using.
