1) Collect data, say for 24 hours with 15 min interval (with Performance
Monitor).
2) Use Performance Tools to produce System report, Component Report and Resource
Report.
System report will give you overall performance stats, while Component or
Resource (do not remember which one, sorry), will give you interval by interval
information about data traffic for every communications line configured on
system.
This will give you information about traffic for different times of the day,
etc.

More hi-tech approach would be to use BEST/1 capacity modeller (included in
Performance Tools).
You can build a model from data, collected in step 1 above.
Then you can vary system configuration for a model (say, change comms line
speeds) and see, how it will influence system performance.
But building a valid model is a major undertaking...

Sorry if I did not follow up on this one, But I was out of the
office(Working at a client site).

What I want to know how do I proceed if I wanted to evaluate the type
of network connection(i.e. ISDN, 512K, T1 etc) I would need if I move My
AS/400(620) to a remote location.

I was planning on installing a 512kbps but I need stats to back it up.

Thanks

PT reports data for all communication cards on system.
Reported statistics includes all data, flowing through the cards.
I am not sure, what is your problem ?

I am planing to move my AS/400 to a remote location(Outsourcing).
But, I am stuck with the task of evaluation the type of network links we are
going to need.

I've ran the performance tool for a week I had a peek utilization of the
communication line of 0.08%.
I have 2 Network cards, both at 100mps(One is connected to an ISDN and the
other to the LAN(10mps)

Does the performance tools take into acount that I have two network cards?
     If not, which one is in monitoring?
And does they include the regular network trafic(Packet sent to other
servers)?
     If so, is there a way to filter it?

Thanks!
