Mauri Kanter WROTE: Good Morning, I managed to start and collect some files (see below) SYSHIS20100829.170256.CNT SYSHIS20100829.170256.MAP SYSHIS20100829.170256.SMP.00 SYSHIS20100829.170256.SMP.01 SYSHIS20100829.170256.SMP.02 with the Hardware Instrumentation services. I couldn't find any reporting facilities ... In particular the .SMP files look binary stuff ... Are there any ? Any help on getting me started ? Here is a page from a Share presentation 1) Customer reports a performance problem on a z10 system 2) IBM instructs customer to collect instrumentation data for diagnosis a) Start HIS b) Modify HIS,Begin,. command to start data collection c) Modify HIS,End -- or - Stop HIS 3) Output: SMF type 113 subtype 2 records (raw counter values) Counter statistics in .CNT USS file (delta ctrvalues) Binary sampling files (.SMP) -one per active CPU Load module/CSECT mapping file (.MAP) 4) Output is returned for analysis Since I am not familiar with BCPii or the HIS functions, I am not sure of their purpose yet. But from this one page, it looks like HIS maybe more for IBM than customer. Also from Cheryl Watson's website, z10 CPU Measurement Facility (CPU MF) - John also described the new hardware instrumentation available on the z10 ECs (GA2) and BCs. The software component is called the Hardware Instrumentation Services (HIS). Because the hardware is collecting the data, there is nearly no impact to the system being measured. IBM can see uses for this in future workload characterization, improving ISV and IBM products, and application tuning. An SMF type 113 record can be produced from HIS, although there are currently no programs to produce reports from this record or the UNIX files that contain the samples. We don't know if these will come later, or be incorporated into a product. ISVs will probably use this facility a lot. I expect to provide a longer article on the CPU MF after more people have tried it. If you do use it, please tell me what you find. If you're going to jump in and use John's handout to run HIS, then I've got some suggestions: 1. Study the documentation carefully before you begin. In addition to John's presentation, you can also look at: Ed Jaffe's SHARE session 2839 (slides 16-21). This has some good examples of output. Greg Dayne's SHARE session 2848 (pages 54-55). This has a good set of steps for implementation. IBM Research article - IBM System z10 performance improvements with software and hardware synergy at http://www.research.ibm.com/journal/rd/531/jackson.pdf. SA22-7627-19 - MVS Commands, Setting up hardware event data collection. SA23-2260-00 - The Set-Program-Parameter and CPU-Measurement Facilities. SA23-2261-00 - IBM The CPU-Measurement Facility Extended Counters Definition for z10. [Editor's Note - The hyperlinks refer to SHARE sessions from the Austin SHARE.] 2. Apply the required APARs: OA25755, OA25750, and OA25773 (z/OS 1.7 - 1.10, Oct2008), and ensure that you have the correct microcode level installed. 3. You can probably safely use COUNTERS mode, which has low overhead (less than 1/100th of a second for the HIS address space during a 15-minute interval). But be careful of using SAMPLING mode because it can produce HUGE volumes of I/O unless you change the sampling frequency. The default of SAMPFREQ=80 and DURATION=10 produces 8 million samples in 10 minutes. Start with a small value (e.g. SAMPFREQ=320), and never go higher than SAMPFREQ=13 for a smaller z10 BC.

Re: Test DASD performance tools
Ron, I understand your viewpoint, but it's hard for a customer shop to choose the RIGHT 24 hours to model. They can pick a worst case, like maybe end-of-month or end-of-year, or they can pick a regular processing day, or anything in between.By providing the tools to the customer, the customer can pick and choose and run multiple scenarios that may be unique to his shop. I've had vendors tell me that this is how your shop will run with this equipment, only to have to remove it within a few months because the vendor didn't tell me the truth. And wouldn't show me the figures from his modeling tool. The whole experience cost my company many thousands of dollars and a lot of weekend time for me. Most of the problem was caused because we used a hierarchical database and used a rather large amount of BDAM access to the database, which the vendor didn't understand and the tool (giving it a lot of credit) didn't account for. Freely granted that BDAM access patterns can be very hard to model. Rick Ron Hawkins wrote: Rick, We were talking about getting vendors to model your performance on their respective offerings, not an existing IO problem. It's the sort of thing that was done by people at BGS that lived in small cells underground and they were occasionally rewarded with raw meat. The proposition is that a vendor can take 24 hour of data an accurately predict your performance with no other input than some SMF records. These DASD controllers can do half a million IOPS and an accurate forecast of performance based on 900 or 1800 second averages over 24 hours is required. And then you have to guarantee that performance for 3 years no matter how the customer grows, shrinks or changes the workload. Have a look at the source code for FlashDA and tell me that it's going to do that :-( While Shane did not go easy on vendors, I thought that one of his points was that this sort of warranty protects the performance guy at a customer site from actually having to understand IO performance. Yes I work for a vendor, but I've spent more time working for customers. No need for me to put shields up, I have a thick skin and head to match. Yes there are many, many brilliant IO performance gals and guys out there working on MVS IO performance. I don't think Shane was referring to anyone in that category.

SMF has a lot of really good averages, but very little in the way of detailed access patterns. Can you tell skip sequential access from random with a Type 74 record? Can a DASD vendor factor your CPU upgrade into a storage model? Will a customer agree not to change their IO patterns for the life of the performance warranty? In less polite company all this would be known as arse covering. The customer wants the vendor to indemnify their (the customers) lack of knowledge (due in no small degree to vendor obfuscation), and the vendors want to extract as much as possible for as long as possible without enlightening said customer. Business as usual to this jaundiced eye. unsnip -- I agree with Shane. You need to explain to this vendor, in no uncertain terms, that YOU are the arbiter of whether this equipment is performing or not, based on the regular performance of YOUR workload.
