Software/Hardware used:
For V5R3, read this topic on Reporting CPU utilization first. Make sure that you can relate the concepts that are discussed there to the performance collection that you are viewing.
The element that seems to be highlighted by your pasted example is that CPU Util Int is always given as "30". When "30" is subtracted from the reported values for CPU Util Tot, the negative batch values are the result. Review the configuration to see if/how interactive capacity is set.
PTFs might be involved. Assuming that the "03/23" dates refer to this week, it wouldn't seem to be from any converted data.

Just as a guess I would think it indicates you are either way behind on PTFs or you are using data that has been converted and was damaged. I’ve seen fields go into an error status from bad performance data so if its just happening on one collection I would probably delete that and work with another collection.
…by using option 7. I noticed there was a NEGATIVE number on my Batch Works Column…
I didn’t look at every possible report, but I didn’t find a “Batch Works Column” anywhere within option 7 functions, nor anything that I could assume would be appropriate. I also checked a full spooled System report and a spooled Jobs report.
Could you copy/paste a portion of the display that shows where the negative value might be seen? Without knowing what item is being asked about, it’s unlikely we can make anything but guesses.

Hi DanD and TomLiotta
Thank you for the response.
Were running V5R3 and this is the first time I’ve encountered a negative performance data.
Option 7 is Display performance data on IBM Performance Tools for iSeries.
I have attached a part of performance report. I’ve been looking in Help files and the net but haven’t been lucky finding the answer.

Thank you tom, and sorry for the late response just got back from a long vacation.
