Performance Monitoring: Arm and Jazz
Matt started a nice Wiki page to enable/setup ARM monitoring of Jazz server
https://jazz.net/wiki/bin/view/Main/EnablingArmMonitoring I decided to use a light version of ARM monitoring before testing the full ITCAM solution. I found the following page about using Eclipse TPTP to trace ARM info: http://help.eclipse.org/help33/index.jsp? topic=/org.eclipse.tptp.trace.arm.doc.user/topics/arm_analysis.htm So far, no success but I will use this thread to log my findings :) Feel free to comment :) -- Christophe Elek Serviceability Architect IBM Software Group - Rational |

I managed to install the JAR files in Tomcat.
It seems anything is running but I cannot see the Monitor Agent. The TPTP team is telling me the agent will show up when the first ARM call is made. So I pinged Matt L in Jazz to see if any ARM call is made. Either no call is made or I setup my configuration improperly Here is what I did 1) I downloaded Eclipse 3.3, EMF and the whole TPTP code 2) I downloaded BTM runtime 3) I downloaded the Agent COntroller from TPTP 4) I modified my serverStartup as follow rem --- START - SUPPORT FOR BtM ------------------------------------------------------ set OLD_PATH=%PATH% set OLD_CLASSPATH=%CLASSPATH% set ARM_LOCATION=C:/TPTP44/ARMLIB/ set RAC_LOCATION=C:/TPTP44/RAC/bin set PATH= %RAC_LOCATION%;%PATH% set JAVA_OPTS=%JAVA_OPTS% -XrunpiAgent:server=enabled set JAVA_OPTS=%JAVA_OPTS% -Dlog.fileHandler=java.util.logging.FileHandler -Dlog.formatter=org.eclipse.hyades.logging.java.XmlFormatter - Dlog.pattern=%ARM_LOCATION%ARM.log -Dlog.btm.severity=INFO set JAVA_OPTS=%JAVA_OPTS% - Dorg.omg.PortableInterceptor.ORBInitializerClass.org.eclipse.tptp.trace.a rm.internal.model.iiop.ArmRequestInterceptor set JAVA_OPTS=%JAVA_OPTS% -Dac.library.path=%RAC_LOCATION% set JAVA_OPTS=%JAVA_OPTS% - DArm40.ArmTransactionFactory=org.eclipse.tptp.trace.arm.internal.transact ion.ArmTransactionFactoryImpl set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote - Dcom.sun.management.jmxremote.port=53284 - Dcom.sun.management.jmxremote.ssl=false - Dcom.sun.management.jmxremote.authenticate=false set JAVA_OPTS=%JAVA_OPTS% -Darm.library.path=%ARM_LOCATION% set CLASSPATH=%ARM_LOCATION%armProbes.jar;%ARM_LOCATION%armLoader.jar;% CLASSPATH% rem --- END - SUPPORT FOR BtM ------------------------------------------------------ call "%CATALINA_HOME%"\bin\startup.bat set "JAVA_HOME=%OLD_JAVA_HOME%" set OLD_JAVA_HOME= set JRE_HOME= set CATALINA_HOME= set CATALINA_OPTS= set JAVA_OPTS= rem --- START - SUPPORT FOR BtM ------------------------------------------------------ set PATH=%OLD_PATH% set CLASSPATH=%OLD_CLASSPATH% set OLD_PATH= rem --- END - SUPPORT FOR BtM ------------------------------------------------------ RAC_LOCATION is the Agent Controller directory. ARM_LOCATION comes from the BTM Runtime Library and points to the JAR files -- Christophe Elek Serviceability Architect IBM Software Group - Rational |
Hi,
could we also use ARM to look behind the scene? (Call Graph etc.) Thanks StH |

If you use WebSphere Application Server (instead of Tomcat), you could
use the Request Metrics functionality in WebSphere to provide the ARM data. Regards, David Brauneis IBM Rational Build Forge Architecture & Development Christophe Elek wrote: I managed to install the JAR files in Tomcat. |
Ok, I am progressing :)
I remotely connect to the Jazz server using Eclipse debugger (pretty neat and pretty simple) and realized I got a NoClassDefFound error. So Ihad to put the arm40 lib in the tomact/common/lib (I need to understand why my classpath I setup in server.startup.bat did not work :( I also had to make sure I had the proper property, somehow my server.startup set a -dArm. property where I need -DArm. Now I am getting a nullPointerException... :) I found the ArmMonitoring start if I connect to http://locahost:9080/web Then when I query the ARM calls are executed.... Stay tuned :) -- Christophe Elek Serviceability Architect IBM Software Group - Rational |
I did it, I did it yeahhh.. (ala Dora the explorer)
I found the NPE was due to the fact that TPTP is checking if I was doing a remote monitoring... So I tricked it :) I started the server then I connected to http://localhost:9080/jazz to see the list of available services then I connected my TPTP to my Agent Controller Et voila, I see the Instrument Collector Agent.... Because I started monitoring before the frst call, I avoid the NPE :) PS: the "jpda start" of catalina is also very nice to attach a remote debugger :) Let me know if you are interested in me elaborating... -- Christophe Elek Serviceability Architect IBM Software Group - Rational |
