Modernize RMF/CMF & SMF Interpretation for Superior z/OS Systems Performance Management
Brent Phillips – Managing Director, AmericasTodd Havekost - Senior Performance Consultant
2
Agenda1. Why Modernize2. Technical Demo with Focus on Emerging Data Sources
‒ Rated Metrics and Exceptions‒ SCRT analysis from SMF 89‒ zEDC hardware compression‒ TCP/IP and OSA‒ Capping & Capping Groups‒ Transactions from SMF 72‒ zIIP SMT
3
z/OS Mainframe• Processes hundreds of billions of transactions per day
• RMF/CMF & SMF are an underleveraged strategic advantage of the z/OS platform‒ Far richer source of performance and configuration
data compared to distributed systems and cloud
• “Big Data” before it was cool‒ But analytics on other big data are far more
advanced. SMF report processes are 4 decades old!‒ So Modernize! It is time to dynamically
create better intelligence out of the data
4
1980’s Technology• Data -> PDB -> Static reports • Often requires:
‒ Programming skills for each new report or report change‒ Difficult, manual interpretation after problems occur‒ Different silos of expertise to piece together the big picture
• Does not:‒ Avoid problems by monitoring root causes for early warning‒ Rate metrics as good or bad based on context‒ Correlate physical and logical views in an integrated data model‒ Show related metrics to the issue, allow intelligent drilldowns‒ Answer: What is different? Is it safe? What will break?

Better Intelligence using AI
AI(4) = Availability Intelligence for yourApplication Infrastructure providingActionable Insights using Artificial Intelligence.
Dynamically derive intelligence from the datathat improves application infrastructure availability
with predictive and prescriptive insights about performance and configuration issues.
13
Utilize applied artificial intelligence techniques that include embedded, z/OS-specific expert knowledge
‒ Derives new, meaningful metrics out of the raw RMF/SMF data
‒ Normalizes the data to properly correlate related metrics
‒ Automatically Rate metrics as good or bad based on context:• Internal component capacity limits (e.g., port throughput) • z/OS best practices for configuration and performance management• Workload balance and redundancy loss identification• Relationship and interaction of logical and physical resources
How to Generate Better Intelligence
14
Better Intelligence = Better Answers to Difficult IT Ops Questions
• What risky conditions exist right now across our entire environment?
• What related metrics are relevant to the context of this issue?
• Where do go next to see root causes?
• What help is there to create a solutions?

Executive Support for Modernization• IT Executives are often already prepped for the strategic
benefits of modernizing with AI
‒ For example, for the second year in a row, Gartner Group named Applied AI as the #1 Strategic Technology Trend
‒ Reasons also valid for Applied AIon the IT Operations Data
20
Benefits of using Applied AI on RMF/SMF1. Availability:
‒ Avoid “Accidents” e.g., with predictive views ‒ Faster root cause analysis e.g., with prescriptive insights
2. Skills Gap:‒ Enhance cross-team knowledge and collaboration‒ Accelerate knowledge transfer for newer team members ‒ Prescriptive insights
3. New Use Cases:‒ Business application owner – App Infrastructure Status Dashboard‒ Application Dev team – compare new version infrastructure impact
21
• Good problem to solve with Software as a Service• Different roles in your organization get easy access to custom intelligence• Access to IntelliMagic experts for knowledge transfer, analysis• Solution infrastructure is managed for you, creating more focus
