In working with IBM Performance Toolkit (z/VM5.2). Screen: FCX105 (graphing a HISTLOG file). I am plotting CPU (% total CPU) and I/O (SSCH/RSCH rate). Does anyone know of a way to maintain a "fixed" scale value for the "Y"
axis in this report (FCX105). It currently changes based on the maximum usage for the reporting period being viewed. That is (we are trying to plot usage on a 24 hour cycle): From 00:00-04:00 "Y" scale = 60 (lower usage) From 04:00-08:00 "Y" scale = 200 (higher usage) From 08:00-12:00 "Y" scale = 100, and so forth. This is confusing - I prefer to have a fixed "Y" axis value based on my input or a standard (ie. always show a scale based on CPU 200 and I/O 200). Its difficult to compare values when the scale value changes. I questioned IBM and they do not know of a way (or do not think it worthwhi le to investigate and develop a way). There is no mention of how to set/change the "Y" scale in IBM's Performance Toolkit manual - it actuall y states that the "Y" scale value changes based on maximum usage reported f or the time period being reviewed. Any suggestions/help would be appreciated. Thanks, Ted
