  1. ITCAM for Application Diagnostics Update

  2. Throughput Health Resources Alerts & Take Actions Problem Determination Memory Analysis Application Trace Overview of ITCAM for Application Diagnostics Benefits • Identify performance and availability issues before they impact users • Enables you to analyze application performance by utilizing trend or historical analysis • Provides key performance metrics to the Tivoli Enterprise Portal to help operations and support teams spot trends and potential delays • Improve MTTR for business critical applications running on WebSphere or J2EE • Enables you to view all JEE transactions that are "in-flight" (have not finished execution) to uncover the root cause of bottlenecks and perform detailed memory analysis • Helps you correlate and profile transactions that span multiple subsystems • Can be used to set resource or application traps to detect and remedy potentially troublesome situations • Software consistency checker compares key system and JVM metrics on working and non-working systems to help isolate differences that may be causing problems • Improved application lifecycle management • Can exchange information with IBM Rational Performance Tester to help developers understand the performance of applications in test or production • Provides developers with a diagnostic tool to identify potential issues prior to rollout

  3. ITCAM for Application Diagnostics – What’s New • Key product enhancements • Dramatically reduce TTV through significant install and config enhancements • Improved ease of use with summary workspaces and contextual drill down to deep diagnostics • Improved problem identification in WebSphere VE environments with new monitoring capabilities • Portfolio simplification for ease of purchase

  4. ITCAM for AD 7.1 Install and Configuration Enhancements • Combine TEMA/DC install and configuration • Reduce the number of install panels • Provide clearer descriptions in the install panels • Silent install • Remote deploy • CAM Configuration Manager (CCM)

  5. Common Diagnostic Scenarios • The following slides show some common diagnostics scenarios using the enhancements introduced in ITCAM for Application Diagnostics • Diagnose a slow or hung application using summary workspaces and launch in context • Diagnose a memory leak using summary workspaces and launch in context • Ensure desired service level for jobs processed by Compute Grid using the new WebSphere VE monitoring

  6. Diagnose a slow or hung transaction The itcamdemo application is red. Flyover shows WASHighResponseTime situation was triggered. Click on itcamdemo icon. The user can launch in-context into the deep-dive features to examine individual transactions. “Diagnostic In-Flight Request Search” link is used in this flow. Flow continues on next slide

  7. Diagnose a slow or hung transaction (cont.) Managing Server Visualization Engine (MSVE) is displayed in TEP workspace Server and request Information are carried over from TEP workspace to MSVE via the link Click on Thread ID to see Stack Trace data of this transaction

  8. Diagnose a memory leak Suspected Memory Leak provides line number information in application code which may cause the memory leak problem.

  9. Key Benefits of WebSphere VE Monitoring in AD 7.1 • ITCAM for AD 7.1 helps to ensure business requirements and SLAs for applications are met • Monitors ODR health and major KPIs to detect and prevent problems in achieving performance and prioritization goals • Example: out of the box alert if ODR queue length is high with contextual drill down to application, deployment targets, and servers to determine cause of queue backup • Deep dive capabilities reduce MTTR (Mean Time To Repair) • Example: out of the box alert that application failed to meet service policy goal with contextual drill down to server causing issue and transaction trace to identify method that is root cause • ITCAM for AD 7.1 reduces problem isolation and diagnosis time in WebSphere VE environments • Visualizes WebSphere Virtual Enterprise and Compute Grid topologies • Contextual drill down from components such as Dynamic Cluster  Individual Server quickly narrows down the problem source • Example: out of the box alert that job is running too long with contextual drill down to job details and deep dive information on call stack shows offending method

  10. Summary • Identify performance and availability issues before they impact users • Displays overall health and availability of web resources in summary views • Identifies performance and availability issues proactively using historical data collection and predictive analytics (predictive trending, baselining, dynamic thresholding) • Helps correlate and profile transactions that span multiple subsystems to isolate the bottleneck • Improve MTTR for business critical applications running on WebSphere or J2EE • Reduces troubleshooting effort with launch in context from operational views to deep dive problem determination tools • Traps on errors such as a slow running transaction and change levels automatically to get detailed problem information • Traces transactions across JVM’s for more precise problem determination • Shows stack trace information for precise problem resolution • Performs memory leak diagnosis • Provides software consistency checker to compare key system and JVM metrics on working and non-working systems to help isolate differences that may be causing problems • Improved application lifecycle management • Feeds trapped problem data directly into Rational test tools • Quicker time to value • Comes ready to monitor and expand into constantly changing environments • Automatically monitors any application changes for complete coverage • Monitors 100’s of JVM’s and applications with a single management server without having to trim critical agent data

  12. Diagnose Workflow for Resolving Composite Application Problems Sense Repair Isolate Detect that a threshold has been breached and that a problem occurred, or is about to happen Pinpoint the problem to a specific part of the environment and hand-off to the appropriate specialist Drill down into the details and get to the root cause of the problem Fix the faulty component, validate the fix and roll back into production • ITM • ITCAM for AD • ITCAM for SOA • OMEGAMONs Deep-dive tools ITCAM for Transactions

  13. Check all resources Response time is terrible; more than one minute. Everything looks normal … but performance is still bad • System Alerts • Health Monitors • OS Statistics • Network traffic • Application log files • Database metrics Bridge Call with Tiger Team Customer Pain – Sensing and Isolating a Problem Today Locate Source of Problem …maybe … • Finger-pointing: "It's the network guy’s fault“ • Recreating the problem is difficult • Problem frequently only discovered “by accident” • Lack of problem isolation capability wastes time, increases MTTR, and costs money

  14. Customer Value – Demonstrating ROI Every customer case will be different … …what do you lose each year due to poor performance?

  15. Composite Application Management and Resource Monitoring • Monitor application response to ensure business expectations are met • Understand transaction flows over complex topologies • Monitor infrastructure performance and availability • Diagnose application performance issues • Increase application availability and customer satisfaction • Improve MTTR and MTBF IT Staff IT Staff Transactions Applications Servers IT Customer 15
