I have written FORTRAN, Rexx and SAS programs for the reduction of accounting and performance data. Luckily this was all for internal review not for real charge-back, no money changed hands. Management only likes my programs when the numbers match their predetermined ideas of who is taking how much of the system. If charge-back is ever required, I will insist that an outside product be purchased and its use written into any service level agreement.
I use accounting data mostly because it is the easiest to play with in Rexx and Pipelines. I would prefer that all of my accounting and performace processing b done from the monitor data. And all NEW data should be put into the monitor stream for processing. With the new STRUCTURE stage in the latest level of Pipelines, I think the processing of Performance Toolkit accumulation files will be a bit easier to do. Perhaps more customers will get around to using the accumulation files of ALL monitor reduction products if the customer had more control over what data gets saved and where. And we should definitely get more control over the data records that actually get passed into the monitor reduction and reporting process. More like the record by record selection for SMF recording in your favorite other operating system. Not just record families like turning on Sample or Event data. /Tom Kern /301-903-2211 Jae-hwa Park wrote:
Thank you for all of you. I think that this redpaper would be helpful for me right now. However as many of you mentioned, it'll be needed some other product for performance monitoring for our customers using zLinux images on z/VM, I think. Anyway, I wonder that how do the customers using zLinux for their business in other countries monitor or charge-back their z/VM and zLinux. Are almost of the customers really using some of product for performance monitoring like ESALPS/Performance Toolkit? If so, how many linux images are running? Or are there some of customers using in-house program for monitoring/charge-back?
