Preparation

  1. Unzip source and binary release archives

    201405-KiekerLectureUPavia $ l kieker-1.9-release/

    kieker-1.9-bin/ kieker-1.9_binaries.zip kieker-1.9_sources.zip kieker-1.9-src/ kieker-1.9_userguide.pdf kieker-webgui-1.9_binaries/ kieker-webgui-1.9_binaries.zip

  2. Start Eclipse with new/empty workspace 201405-KiekerLectureUPavia/eclipse-workspace/

Quick Start

  • Presentation of Release Archive (Binary, Source, User Guide)

  • Import the following examples (to be found in examples/userguide/ of the binary release) into Eclipse:

    • ch2–bookstore-application/

    • ch3-4–custom-components/

    • ch5–trace-monitoring-aspectj/

  • Bookstore example with AspectJ from the user guide

    1. Bookstore without Instrumentation (ch2–bookstore-application)

      1. Briefly present Bookstore application

      2. Start without instrumentation: BookstoreStarter.java -> run as -> Java application

    2. Instrumentation with AspectJ (Full instrumentation without annotations)

      1. (Partially workaround due to #1292)

      2. Copy lib/ folder (including kieker-1.9_aspectj.jar) from ch5–trace-monitoring-aspectj/ to ch2–bookstore-application

      3. Create directory src/META-INF

      4. Copy aop-full.xml from ch5–trace-monitoring-aspectj/ to ch2–bookstore-application/src/META-INF/aop.xml

      5. run with -javaagent:lib/kieker-1.9_aspectj.jar

    3. Filesystem-Log

      1. Show console output

      2. Show .map and .dat file in Konqueror

      3. Run trace-analysis{-gui}.(sh|bat)

      4. Convert .dot files to .pdf (e.g., with convertLoggingTimestamp.{sh|bat})

      5. Show output

        1. HTML system model

        2. Dependency graphs (Deployment-Operation + ggf. mehr)

        3. Call tree variants

        4. Sequence diagrams -> “if possible”

Monitoring

  1. Show example records, e.g.,

    • CPUUtilizationRecord

    • MyResponseTimeRecord (from ch3-4–custom-components)

  2. Show example probes, e.g.,

    • CPUsDetailedPercSampler

    • Manual instrumentation in Bookstore (from ch3-4–custom-components)

  3. Show example writer, e.g., MyPipeWriter (from ch3-4–custom-components)

Analysis

  1. Show example reader, e.g., MyPipeReader (from ch3-4–custom-components)

  2. Show example filters, e.g.,

    • MyPipeWriter (from ch3-4–custom-components)

    • MyResponseTimeFilter (from ch3-4–custom-components)

  3. Show how to assemble and start pipes-and-filters configuration, e.g., in Starter (from ch3-4–custom-components) -> motivation for WebGUI

WebGUI

  1. Mem/swap example without CPU (to be prepared)

  2. Open analysis editor

  3. Explain example

  4. Add CPU filter

  5. Start analysis

  6. Cockpit

JavaEE

JPetStore and Live Demo (via JMX)

  1. Change dir to prepared Jetty 201405-KiekerLectureUPavia/kieker-1.9-release/kieker-1.9-bin/examples/JavaEEServletContainerExample/jetty-hightide-jpetstore

  2. Start instrumented JPetStore

    jetty-hightide-jpetstore <master>* $ java -jar start.jar

  3. Access JPetStore http://localhost:8080/jpetstore/ and click around

  4. Access live demo http://localhost:8080/demo/

Log to Filesystem and use TraceAnalysis

  1. Activate file system writer and adaptive monitoring by editing jetty-hightide-jpetstore/webapps/jpetstore/WEB-INF/classes/META-INF/kieker.monitoring.properties

    …

    ## Enable or disable adaptive monitoring.

    kieker.monitoring.adaptiveMonitoring.enabled=true

    #By comment out the next line, the FSWriter is used. This makes the demo inoperable.

    #kieker.monitoring.writer=kieker.monitoring.writer.jmx.JMXWriter

  2. Restart Jetty

  3. Click around a bit

  4. Show file system monitoring log

  5. Attach to Monitoring Controller via JConsole:

    /usr/lib/jvm/sun-jdk1.6.0_38/bin/jconsole &

    1. toString

    2. Demonstrate adaptive Monitoring

      1. Disable CPU (%CPU) and memory (%MEM_SWAP)

      2. Disable public void kieker.monitoring.probe.servlet.SessionAndTraceRegistrationFilter.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)

      3. Activate *

    3. enable/disable

  6. Create and show plots

    jetty-hightide-jpetstore <master>* $ mkdir plots

    jetty-hightide-jpetstore <master>* $ ../../../bin/trace-analysis.sh -i /tmp/kieker-<path-to-log>/ -o plots/ –plot-Deployment-Component-Dependency-Graph –plot-Assembl

    y-Component-Dependency-Graph –plot-Deployment-Operation-Dependency-Graph responseTimes –plot-Assembly-Operation-Dependency-Graph responseTimes –print-System-Model

    jetty-hightide-jpetstore <master>* $ ../../../bin/dotPic-fileConverter.sh plots/ pdf

    jetty-hightide-jpetstore <master>* $ acroread plots/*.pdf&
