On our environment we use nmon record files (instead native agent).
Today we found one lpar that its "Paging 2" tab / graph , was not right. (ie: real paging is 15% , and graphs showing only 5%)
So, for test purposes , we started graphing with the agent script as well: Agent is working right, its shows the real paging space being used.
We ugpraded to Version 6.0 (around 2 weeks ago)
So far its the only lpar where we find this issue.
