Re: IBM z/VM 5.2 Performance Toolkit
I think a bigger problem with requiring GDDM is that the use of it has fallen so much due to the PC connected terminals. GDDM was great when it was the best way to get a nice looking graph or chart. Requiring GDDM now makes about as much sense as requiring real, not virtual card input. I still have 5081 cards, but I'd hate to punch them full of holes even if I could find a key punch and a 2540 card reader.

Re: IBM z/VM 5.2 Performance Toolkit
Even bigger problem is finding a tn3270 client that understands 3270 graphics (at least for Windows -- thank you Brown University for the Mac tn3270!) (yes, I know GDDM does more than 3270, but it's hard to justify the other devices if you can't preview the output before you send it off to them...)
Re: IBM z/VM 5.2 Performance Toolkit
I think it's safe to say that GDDM, as good as it was in it's day, is a thing of the past now. But I still use it occasionally here, and the the IBM PCOMM3270 emulator supports it and it's two separate graphics formats just fine. DJ A.

Re: IBM z/VM 5.2 Performance Toolkit
This is drifting a bit off topic, but the IBM PC/AT-G, and PC/AT-GX (I think that's correct, the G was for Graphics) were very popular in the oil gas business in the late 80s, early 90s...they were dual headed bocks that ran GDDM-PCLK (PC link) and GDDM had support for developing interesting graphical applications. One screen could show a 3270 full screen type session, and the other screen a map or geologic cross section.very nice package. A lot of the actual vector rendering processing was off loaded the the PCs themselves, so GDDM did have to do as much work up on the host. You could even interact with the graphics locally (pan, zoom, print, save, etc.) They even supported a small digitizer type board. I still have around here some place some geologic modeling programs I developed for those boxes. DJ I seem to recall that IBM had a GML (DCF) type editor for PC-DOS as well.

When I was young, I did have a short but interesting relation with the GDDM-PCLK product. I think it used the same structured field file transfer as IND$FILE to get the graphics data to the workstation application for display and printing. It's probably now somewhere with the GML editor and the PROFS front-end... ;-) Rob
Re: IBM z/VM 5.2 Performance Toolkit
Ted, as Thomas Kern wrote, the graphics work just as intended: I liked (and still prefer) the idea of automatically adapted scales when using the tool for performance analysis .. But I agree that for capacity planning purposes or general statistics a fixed scale is often better. The clean solution would obviously be to allow telling PerfKit about the preferred scale, but there's no way to do so now, and you'll have to convince Endicott to implement it. In the absence of that possibility you can try different ways to achieve a similar result: A) My approach would have been to just plot the WHOLE period you're interested in. That way you'll always have a good graph for the day, and have a good chance of seeing the same scale also on other days. And if it's for statistical purposes the whole day is probably better anyway. If you really need graphics for shorter periods the following may help. B) Plot both the variables CPU and %WT, and specify 'cumulative' display: Since the total of the two values should be a constant you should end up with a fixed scale. The drawback is that you cannot include in the same output other variables whose value should not be cumulated, too (such as IO/S). C) Plot CPU, IO/S and %WT, non-cumulative. Since PerfKit will try to use the same scale for similar variables (with the same unit type, in this case '%CPU') the CPU and %WT values should be plotted in the same scale. Will probably achieve the fixed scale you want, and you can still include I/O as well. The drawback is that you end up plotting the %WT variable that you don't really want. D) You can also try to - define a fixed 'user variable' with the max. scale to be used, and a unit type of '%CPU' - plot this user variable together with 'CPU'. Since PerfKit will try to use the same scale for variables of equal units the large (user) variable should determine the scale. However, I'm not really sure whether this will work: it may depend on the internal representation of the values (e.g. number of decimals), and then the user variable could end up being not quite the same. I just don't remember (and I doubt anybody ever tried it) .. BTW: Do you really use the primitive 3270-mode PLOT screen FCX105? I had assumed that by now everybody would be using the Web interface to create real graphics.

Re: IBM z/VM 5.2 Performance Toolkit
We (at NY State) have the same issues with our Network Group on enabling browser based access. At best non-responsive. In any case... We also run OMEGAMON to extract performance data (another Group). I do have acces to that, however we (the VM Systems Programmers) want to have a separate means of performance reporting (both for comparison and arguement). I have little experience using Performance Toolkit, thus my question. PTK does seem to provide some value in their predefined and custom reports, but has it limitations - which we are discovering. Sounds like further investigation (of other prodcuts is in order. As for GDDM, we don't run that product on our IFLs, only on our Agency LPARs. We currently run 4 Agency (full) LPARs a nd 4 IFLs (LINUX).

Re: IBM z/VM 5.2 Performance Toolkit
My feeling is that the graphics in the Performance Toolkit satisfy the interests of the original author. If you want more, you need to go to a real graphics package. GDDM comes to mind, but so do some vague unpleasant memories, but I do think that dual scales (a left hand scale for CPU and a right hand scale for I/O or TrivResp) is possible. Personally, I extract the data from PTK and use GnuPlot on my windows workstation to design a plot. When I am satisfied, I transfer the control information and updated data to a Linux system for batch creation of graphics that can be emailed to managers or displayed on a web page. Something that my Linux associates are urging me to look at is the RRDTOOL for the accumulation and display of this time-based performance data. The BigBrother monitoring package does a interesting job of presenting some data (examples available on request). /Tom Kern --- Ted Lewis [EMAIL PROTECTED] wrote: In working with IBM Performance Toolkit (z/VM5.2).
