IBM Performance Optimization Toolkit Overview
Who are the IPOT users?
 Any developer who wants to identify root cause of
performance problems and accelerate problem determination
occurring in development environment.
 Any tester who wants to identify root cause of performance
problems and accelerate problem determination occurring in
test environment.
 Any support developer who wants to identify root cause of
performance problems and accelerate problem determination
occurring in production environment.

Session: SDP14
IBM Performance Optimization Toolkit Overview
Why would they use IPOT?
 IPOT provides transaction decomposition for application
optimization
 Allows the developer/tester to monitor a distributed application in
real-time
 Provides a Data Collection Infrastructure (DCI) for real-time
monitoring
 Integrates with Rational Software Development Platform
 IPOT accelerates problem determination by correlating the
different data collection views (logging, performance and
resource monitoring data) by time.
 IPOT allows to import data from production environment and
visualize it for analysis and correlation in the development/test
environments.

Instrumenting your Application Server
 DCI provides a script to help instrument your application server
(instrumentServer.bat or instrumentServer.sh located in the
<INSTALL_HOME>rpa_prod directory).
 Run without any parameters will display a help screen.
 The WebSphere server that you want to instrument MUST BE
RUNNING before instrumentation and MUST BE RESTARTED
after instrumentation.
 Example
 instrumentServer –install –type IBM –serverName server1 –
serverHome “C:Program FilesWebSphereAppServer” –
serverVersion 5
 BEA WebLogic™ is also supported

Profiling a J2EE Application
 Profile distributed applications in real-time
 Import application trace data after an application has executed using
TMTP or ITCAM

Steps to Problem Determination
 Application log events are generated during execution
 Correlation of these log events with events during resource
monitoring and application trace help identify the problem
 Correlation between log events from different systems, such as
application servers and data base systems, help identify
problems
 Common logging and trace format through Common Base
Event – OASIS standard
 Over 115 adapters for log conversion (Generic Log Adapters)

Editor's Notes

  1. Please note that if you simply apply this template to your existing presentation, you risk not updating the notes and handouts masters of your presentation. Please follow the steps below to copy your existing slides into the new template. 1. Download the new template to your hardrive 2. Open existing presentation that needs to be updated with the new template 3. Go to slide sorter view from the &amp;quot;View&amp;quot; menu 4. Press &amp;lt;Control&amp;gt; &amp;quot;A&amp;quot; to select all slides in this view 5. Press &amp;lt;Control&amp;gt; &amp;quot;C&amp;quot; to copy all slides in this view 6. Select &amp;quot;Open&amp;quot; from the File menu and open the new template 7. Go to slide sorter view from the &amp;quot;View&amp;quot; menu 8. Press &amp;lt;Control&amp;gt; &amp;quot;V&amp;quot; to paste the slides 9. Select slides 1 and 2 which are no longer needed in your presentation and press &amp;lt;Control&amp;gt; &amp;quot;X&amp;quot; to cut 10. Select “Save As” from the File menu and rename the file Reformatting Issues: Replace Fonts (especially Times New Roman) Due to a PowerPoint limitation, it’s advisable to run the “replace fonts” option after applying the template Select Format/Replace Fonts and select desired font to be changed (Times New Roman and Arial are commonly seen here to be replaced with Arial Narrow) Correct Colors - graphic objects and text created not using the auto layout features may not automatically convert. Some reformatting may be necessary. If slide background colors are incorrect, reset slide background color to autocolor If graphics are colored incorrectly, use the colors that are built-in to the template already as these are pre-approved colors Slide Layouts It may be necessary to reapply slide layouts to problem slides. To do this, from the View menu, make sure “Task Pane” is selected. Select “Slide Layout” from the Task Pane and select the desired layout to reapply. Sometimes this action needs to be applied twice in order for layout to readjust.
  2. i/t has to be on demand just as much as the business has to be on demand w/ their clients =&amp;gt; IBM has to respond to that - Optimize application before deploying to prevent problems before it happens in the first place Reduce business downtimewhile accelerating business value throughput… Quickly discover and understand application-level errors even after deployment Speed Tivoli-aware application fix and (re)build Optimize and accelerate (re)deployment …by bridging developmentand operations teams
  3. Example: Trying to run a test to identify if performance problems exist in a multi-user environment. Diagram: Can be distributed on separate machines. Workbench collect performance and resource monitoring data import data from historical systems Data Collection Infrastructure (DCI) Data Collection Agent IBM Tivoli Data Collection IBM Remote Agent Controller IPOT Agent is reported the ARM Events. ARM Events are collected and organized into a transactional hierarchy, from the root transaction to all of its sub-transactions. This hierarchy is then converted into TPTP Trace events and sent to the Presentation System. Need DCI installed on the Presentation System if trying to Profile J2EE Performance Metrics while executing a Performance Schedule or Test. Resource Monitoring We provide data collection (via the RAC) from Windows/Linux machine, JBoss/JOnas IPOT adds value by having the ITM infrastructure in place because they support a wide array of ITM agents
  4. There are two WebSphere configuration files that get changed during instrumentation: (WAS5) &amp;lt;WAS_HOME&amp;gt;\config\cells\&amp;lt;cell_name&amp;gt;\nodes\&amp;lt;node_name&amp;gt;\servers\&amp;lt;server_name&amp;gt;\server.xml and variables.xml. (WAS 6) &amp;lt;WAS_HOME&amp;gt;\profiles\&amp;lt;profile_name&amp;gt;\config\cells\&amp;lt;cell_name&amp;gt;\nodes\&amp;lt;node_name&amp;gt;\servers\&amp;lt;server_name&amp;gt;\server.xml and variables.xml. To manually verify that instrumentation was successful, check that these two files have changed from their pre-instrumentation state. In particular, check in server.xml that the ‘jvmEntries’ element has a new string in the ‘genericJvmArguments’ attribute. Websphere Express is NOT supported. Only Websphere Application Server is supported. - genericJvmArguments=“-Xbootclasspath/a:${MA_INSTRUMENT}\lib\jiti.jar;${MA_INSTRUMENT}\lib\bootic.jar;${MA_INSTRUMENT}\ic\config;${MA_INSTRUMENT_APPSERVER_CONFIG} -Dma.instrument=${MA_INSTRUMENT} -Dma.appserverconfig=${MA_INSTRUMENT_APPSERVER_CONFIG} -Dtmtp.user.dir=C:\Programs\IBM\Rational\SDP\6.0\rpa_prod\TIVOLI~2 -Dcom.ibm.tivoli.jiti.config=${MA_INSTRUMENT_APPSERVER_CONFIG}\config.properties -Dcom.ibm.tivoli.transperf.logging.qualDir=${MA_LOG_QUALDIR} -Dcom.ibm.tivoli.jiti.probe.directory=C:\Programs\IBM\Rational\SDP\6.0\rpa_prod\TIVOLI~2\app\instrument\5301\lib\ext -Dws.ext.dirs=C:\Programs\IBM\Rational\SDP\6.0\rpa_prod\TIVOLI~2\app\instrument\5301\lib\ext -Djlog.propertyFileDir=${MA_INSTRUMENT_APPSERVER_CONFIG} -Xrunvirt_5301:agent=ijitipi_5301:${MA_INSTRUMENT_APPSERVER_CONFIG}\jiti.properties,agent=piAgent:server=enabled You will see a number of additional entries in variables.xml with the attribute symbolicName prefixed with “MA”. E.g. &amp;lt;entries xmi:id=&amp;quot;VariableSubstitutionEntry_1115417429895&amp;quot; symbolicName=&amp;quot;MA_LOG_QUALDIR&amp;quot; value=&amp;quot;J2EE/server1_100&amp;quot; description=&amp;quot;Base directory for logging for the TMTP Management Agent&amp;quot;/&amp;gt; There is also an IPOT DCI specific file that gets updated when instrumentation occurs. This file is located in &amp;lt;INSTALL_HOME&amp;gt;\rpa_prod\tivoli_comp\app\instrument\5301\bin\InstrumentationRegistry.xml This file contains an entry for every server that has been successfully instrumented. The entry will look something like: &amp;lt;applicationServer type=&amp;quot;IBM&amp;quot;&amp;gt; &amp;lt;name&amp;gt;server1&amp;lt;/name&amp;gt; &amp;lt;path&amp;gt;C:\WebSphere\AppServer6&amp;lt;/path&amp;gt; &amp;lt;type&amp;gt;2&amp;lt;/type&amp;gt; &amp;lt;secured&amp;gt;false&amp;lt;/secured&amp;gt; &amp;lt;keepPiAgentStr&amp;gt;false&amp;lt;/keepPiAgentStr&amp;gt; &amp;lt;/applicationServer&amp;gt;
  5. Circled launch configuration types are IPOT-specific. Others come from TPTP, RPT, RAD and Eclipse. ARM Instrumented Application is for profiling non-J2EE applications or custom ARM instrumented applications. ARM – Application Response Measurement, an open standard. Use J2EE Application when profiling a J2EE Application that is load driven from a browser.
  6. IPOT contributes two profiling sets J2EE Performance Analysis ARM Performance Analysis Profiling sets are configurations of profiling types with specific options, much like launch configurations. Users can define custom sets. Profiling types have options to indicate what to include and exclude during data collection These two sets apply only to the IPOT agent, not for the TPTP JVMPI (Java Virtual Machine Profiler Interface) agent. JVMPI agent resides on the same process as application being profiled IPOT agent behaves similar to a service, as it runs in its own process, and profiles all ARM instrumented applications that execute on the system IPOT agents support a distributed environment and the workbench will automatically display all IPOT agents involved in a distributed transaction.
  7. Components tab in J2EE Performance Analysis lets the user specify which J2EE components they wish to collect data from. This is applicable for both IBM Websphere™ and BEA WebLogic ™ application servers. We can also profile applications that have been instrumented with custom ARM calls.
  8. ARM profiling type allows you to filter applications and transactions to profile, and allows you to do sampling of transactions. Application filter matches the name of the application that was registered with the ARM engine. All ARM-enabled apps must set this. Transaction filter matches the ARM transaction name. This is an arbitrary name set by the ARM-enabled application.
  9. Sampling tab allows you to control the frequency of which data is collected. This tab is the same for ARM and J2EE Performance Analysis
  10. IPOT contributes two profiling sets J2EE Performance Analysis ARM Performance Analysis Profiling sets are configurations of profiling types with specific options, much like launch configurations. Users can define custom sets. Profiling types have options to indicate what to include and exclude during data collection These two sets apply only to the IPOT agent, not for the TPTP JVMPI (Java Virtual Machine Profiler Interface) agent. JVMPI agent resides on the same process as application being profiled IPOT agent behaves similar to a service, as it runs in its own process, and profiles all ARM instrumented applications that execute on the system IPOT agents support a distributed environment and the workbench will automatically display all IPOT agents involved in a distributed transaction.
  11. End to end transaction UML view with a performance problem for the problematic transaction. On the scale on the right, the user can see the different shades of red beside each method calls. The darker red on the scale, the more time is spent in this location in the problematic transaction. The user can then jump to the source code from this view.
  12. The user can the switch to the Method details views to view as well the time spent in the descendant methods called from this transaction. The user can then jump to the source code from this view.
  13. As well, we provide method statistics views showing to the user how many times a methods was called and what is the average time spent in this method. The user can then jump to the source code from this view.
  14. Finally, the user can go to source code from the previous views to identify performance problem
  15. Workbench collect performance and resource monitoring data import data from historical systems Data Collection Infrastructure (DCI) Data Collection Agent IBM Tivoli Data Collection IBM Remote Agent Controller Workflow: The RPT client is the edge of the transaction (where ARM transactions are first generated). Therefore, all page are transacted from the presentation system, which behaves similar to a browser, by placing HTTP requests for all page elements (belonging to their respective pages). For all HTTP Requests, RPT adds the ARM_CORRELATOR header attribute to the request. Multiple RPT clients can generate the same load for the same transactions and they will be collected by the ARM engine independently. Anything downstream from the RPT client (for example a webserver or J2EE appserver) must be instrumented with J2EE Monitoring Component (or Tivoli Data Collection, which consists of probes or hooks) that knows how to detect the ARM_CORRELATOR header attribute and then make the appropriate ARM calls to the ARM engine. Once the probe makes the ARM call, the transactions are all treated the same by the ARM engine. In order to see “into” the application (at the method level) when the RPT test/schedule is executed, the Execution Environments involved muse be instrumented, just the same as one would do with TMTP or the IPOT DCI, so that the RPT HTTP Requests can be correlated with the AppServer’s behavious. Caspian: Architecture will change so that IPOT is not dependent on RPT, however, RPT becomes dependent on IPOT. Allowing other products to leverage the toolkit. IPOT Agent is reported the ARM Events. ARM Events are collected and organized into a transactional hierarchy, from the root transaction to all of its sub-transactions. This hierarchy is then converted into TPTP Trace events and sent to the Presentation System. Need DCI installed on the Presentation System if trying to Profile J2EE Performance Metrics while executing a Performance Schedule or Test.
  16. Circled launch configuration types are either IPOT-specific or come from TPTP. Tivoli Monitored Host is for monitoring counters from IBM Tivoli Monitoring (ITM) Host – Linux monitors Linux-based operating systems via the Rational Agent Controller (RAC) Host – Windows is perfmon monitoring via the RAC J2EE App Server - JBoss is monitoring via JMX J2EE App Server – JOnAS is monitoring via JMX
  17. The user can also import different log files from production as well into an aggregated view with filtering and analysis results using the symptom database
  18. Steps to determine the cause of the problem: using performance data Collect performance data using the DCI Performance data allows the tester and developer to peer into the behaviour of the application or service at a programmatic level (ie. The method level) This approach provides solid evidence of where the potential problem is located and increases efficiency in problem determination between the tester and developer, thereby, effectively reducing the time to identify and diagnose performance problems. Real-time data collection using the Data Collection Infrastructure (DCI) for ARM-instrumented applications Application Response Measurement (ARM) is an open standard from OpenGroup
  19. End to end transaction UML view with a performance problem for the problematic transaction. On the scale on the right, the user can see the different shades of red beside each method calls. The darker red on the scale, the more time is spent in this location in the problematic transaction. The user can then jump to the source code from this view.
