Knew I forgot a piece of info. I'm seeing this from the perf tool kit display using the DDS code on each server. Option 29 under the perf toolkit if for linux images. I think it correlates to FCX115 display that shows some detail for each machine but am not sure. I believe now from your note that it must be the XSTORE pages I see in the FCX115 display. XSTORE pages : 16793
If I move the cursor up to the Page-in rate and hit PF1 for help, I get this...
Page-in rate The number of pages paged in per second.
Just didn't know what the difference was. I'm not swapping from what I can tell, but there is paging and I just don't know what the difference is.

Hi Brian: Where are you getting this data from? zvm doesn't "swap" it pages. It will page to expanded storage and/or dasd, and migrate pages from xstore to dasd paging. It will form blocks of pages, but swapping, per se, hasn't existed in vm since, well, hpo.
What product is reporting this data? Is this linux data, which would also be a strange reporting method?

Would someone please shed light on the following for me. What is the
dif from swaping to paging other than swaping is using the swap
space? I can't seem to find much info on paging? I believe if I'm
swapping heavily that's bad, but where does the pageing go and is it
bad for perf? THANX!!!
% Swap space used 0%
Swap-in rate 0/s
Swap-out rate 0/s
Page-in rate 0.066/s
Page-out rate 50.133/s
