One could build a perfectly servicable performance monitor from those two data sources alone. You might want to augment that with RMF data from the RMF API if you really wanted to, but I would not bother. I would really only be interested in goal attainment and figuring out why goals were being missed. As for the sysplex-wide PI, keep in mind that like in politics, everything in WLM is local. The sysplex-wide PI is a piece of slightly interesting tourist information that might or might not be used by WLM in making server routing decisions. For the most part you can just ignore it. Everything that matters is local. You can calculate the moment by moment PI for each active service class period by calling IWMRCOL every so often (no more frequently than 10 seconds apart because the stats won't change more frequently) Bear in mind that the data are cumulative, so you save observation 1 and then get the delta by subtracting observation 1 from observation 2. The computation for velocity is obvious, but the response goal PI calculations are counter intuitive to say the least. You will also find quite a few disturbing inconsistencies in the data. There are strategies for dealing with those but they are a bit of a dealer's choice. Also, you may have to deal with a wrap in the stats for a given service class period. Oh and the layout of the data in memory is given by mapping DSECTS but it can be a challenge to put them together correctly. Other tid-bits. There are a few ENF signals of interest and from your questions you probably ought to check out ENF43 for use in conjunction with IWMRQRY. If you need to pull out the big guns for analysis you can use the IEFU8x exit(s) to snarf up SMF99 records to really understand what WLM is doing. But that's not a summer project.
