3. 3 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 - application performance management vs application performance monitoring -application performance management refers to the processes and procedures used to ensure applications have and meet performance goals. application performance monitoring is a piece of this. -application performance monitoring refers to the use of tools to gather metrics, real time status, identification. this can be done throughout the software development lifecycle (sdlc) -performance falls under the ITIL discipline of Availability Management -In accordance with ITIL, the primary objective of the Availability Management process is to define, plan, evaluate and improve all aspects of the availability of IT services, establishing and maintaining them in compliance with agreed availability targets. These aspects include the people, process and technology factors of availability. 2 what is apm? 2 Availability Management: http://www.ca.com/files/processmaps/availability-mgmt-process-map_222472.pdf St Louis

5. 5 levels of monitoring —monitoring occurs at various levels and by different audiences −end user experience what is your customer experiencing? −business transactions how are the individual business transactions performing? −architecture how are the systems performing for all things running on it? −software how are the individual components that make up the business transactions performing?

12. 12 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —the business defines what the problem is, in essence, what the application is to do —requirements are gathered −end user response time goals —business transactions are determined −ex: Balance Inquiry —business volume metrics are built system analysis St Louis

15. 15 design —Describes desired features and operations in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation. —performance management begins with application design. get involved early! —have baselines of the proposed architectures available to help in your decision making −data sources: own environment metrics, vendor metrics, industry experts —build the Application Performance Budget Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 St Louis

16. 16 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —Application Performance Budgeting is an approach to ensure applications meet their response time objectives and proactively mitigate performance concerns at any phase – development, performance testing, production. —Always updating and validating —May assist in identifying performance bottlenecks and inefficiencies. —A Performance Budget breaks down a transaction to allow for the developer to code to requirements and enable operations to maintain the application and continue meeting design specifications. application performance budget St Louis

17. 17 application design and the performance budget —identify the required pieces of the application before a single line of code is written −data sources and locations −security/authentication requirements −hardware hops —measure the infrastructure response times. before a single line of code is written, you know the fastest this application will ever run! Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 St Louis

18. 18 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 build the application performance budget -start with what you know. use existing metrics, industry standards, vendor metrics -start by allocating time across the tiers for each transaction class to add up to the maximum response time.

21. 21 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —create a performance gateway where the performance team reviews the performance testing numbers and must sign off before the application can be implemented into your production environment. −this is the final opportunity to keep poor performing applications from being implemented into production −this also gives you an opportunity to acquire necessary capacity planning numbers implementation St Louis

22. 22 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —once in production, capture performance data for these transactions and compare to your application performance budget and validate your model —if large discrepancies, look at why? −test infrastructure is too different than production −BVM’s are incorrect −database inefficiencies validation St Louis

23. 23 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —can improvements be made? −can I tune the infrastructure? more cics or ims regions classify and group workload –horses, rabbits and elephants caching −can I tune the application? break transactions into multiple pieces verify database indexes are the same in production as tested against evaluation St Louis

24. 24 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —implement the application dashboards built during performance testing into the production environment —compare performance test numbers to production numbers —set up thresholds and alerts based upon these numbers —publish performance goals for transactions −example: 95% of CICS transactions must be 0.5 seconds or less application performance monitoring St Louis

25. 25 Tom Quinn Kayaks and Cruise Ships - Application Performance Management August 23, 2011 —the earlier you get involved, the earlier performance problems can be identified and corrected —build in a performance gateway to approve or deny new and changed applications that will/will not perform —maintain application performance budgets for future development get engaged early and often St Louis
