• Get and unzip Fuse archive (let's call the Fuse's directory $FUSE). Out-of-the-box it is prepared for the Fuse version 6.2.1.redhat-084.
• Enable admin user (with password admin) by uncommenting following line in $FUSE\etc\users.properties file.

admin=admin,...

• Bind ActiveMQ network interfaces to to 0.0.0.0 by setting activemq.host property in $FUSE\etc\system.properties file.
• Enable MQTT connector of ActiveMQ by adding following transport connector in $FUSE\etc\activemq.xml file:

<beans>
    ...
    <broker>
        ...
        <transportConnectors>
            ...
            <transportConnector name="mqtt" uri="mqtt://${bindAddress}:1883"/>
        </transportConnectors>
     </broker>
</beans>

• Install camel-mqtt feature by default by adding it to featuresBoot property in $FUSE\etc\org.apache.karaf.features.cfg file:

...
featuresBoot=\
        ...,\
        camel-mqtt
...

A benchmark test consists of 2 parts:

• Tested bundle (server side)
• PerfCake scenario (client side)

All tested bundles are Maven projects that can be build by the following command:

mvn clean package

After a successful build there is a jar file (the bundle) prepared in target directory.

Note: Currently and out-of-the-box the benchmark is set for the version 6.2.1.redhat-084 of Fuse. The version numbers can be overriden by setting the following Jave system properties for the maven build:

-Dfuse.major.version=6
-Dfuse.minor.version=2
-Dfuse.micro.version=1
-Dfuse.build.version=084

The bundles uses Apache ActiveMQ and CXF artifacts whose versions are set to the particular versions that are part of Fuse as well. To override those versions, use the following Java system properties during the Maven build:

-Dversion.activemq=...
-Dversion.cxf=...

To deploy the tested bundle simply place the bundle jar file built in the previous step into $FUSE\deploy directory.

• Get PerfCake

  Note: PerfCake (Currently version 7.0-SNAPSHOT is necessary to run the benchmark)

• Unpack the archive into a directory of your choice and let's call it $PERFCAKE.

• Place PerfCake scenarios (all the files from fuse-benchmark\perfcake\scenarios directory) into $PERFCAKE\resources\scenarios directory

• Place scenarios' messages (all the files from fuse-benchmark\perfcake\messages directory) into $PERFCAKE\resources\messages directory

The Fuse should be running with the particular bundle deployed and started

• Execute the PerfCake scenario by running the following command:

$PERFCAKE\bin\perfcake.sh -s <scenario-name> -Dserver.host=<fuse-hostname>

where: <scenario-name> is the name of the scenario file without the .xml extension and <fuse-hostname> is the network address (hostname or IP address) of the machine where Fuse is running.

• Wait for PerfCake to to finish. The scenarios are configured to run with 100 concurrent threads for 5 minutes (plus a warm-up period) using 1kB message. You'll see the progress and partial results in log output for the whole duration of scenario execution.

Note: The duration, number of threads or message size can be tweaked by the following Java system properties set during the PerfCake run:

• perfcake.run.type - the type of the duration, one of time or iteration
• perfcake.run.duration - amount of time (in milliseconds) in case of time run type, or the number of iterations in case of iteration run type
• perfcake.thread.count - the number of concurrent threads (number of clients)
• perfcake.message.size - the message size, one of 1B, 16B, 1kB or 5kB

The previous (default) command is equivalent to:

$PERFCAKE\bin\perfcake.sh -s <scenario-name> -Dserver.host=<fuse-hostname> -Dperfcake.run.type=time -Dperfcake.run.duration=300000 -Dperfcake.thread.count=100 -Dperfcake.message.size=1kB

After a successful run of the PerfCake you will find the results in 2 forms:

• CSV files $PERFCAKE\<scenario-name>-<message-size>-throughput-stats-<timestamp>.csv and $PERFCAKE\<scenario-name>-<message-size>-response-time-stats-<timestamp>.csv with the history of the benchmark run, where the last record is the final result.
• A HTML report with nice charts found in $PERFCAKE\<scenario-name>-charts\index.html directory.

Both reports show the same data.
