JMeter Command Line Interface and Usage

Editing the default in the bin/JMeter.properties file

The following properties affect the summariser:

# Define the following property to automatically start a summariser
# with that name(applies to non-GUI mode ony)
summariser.name=summary
#
# interval between summaries (in seconds) default 3 minutes
summariser.interval=180
#
# Write messages to log file
summariser.log=true
#
# Write messages to System.out
summariser.out=true


[root@OCMPRBT2 bin]# ./jmeter -n -t /space/ukrain/voicemail/JmeterTest/myTest.jmx -l logOut.jtl &

summary + 108 in 21.8s = 5.0/s Avg: 1291 Min: 229 Max: 6317 Err: 0 (0.00%)

summary = 206 in 52.5s = 3.9/s Avg: 1827 Min: 229 Max: 6974 Err: 0 (0.00%)



The lines with "summary +" are incremental for the latest summariser period, the lines with "summary =" are cumulative. The above was with a summariser period of 20 secs, you can see the actual periods can sometimes be longer than the specified period and the length of the very first period is somewhat random. You get the throughput statistics as well as average, min and max response times, and how many errors were detected (assuming your JMeter test plan as assertions to detect errors).

JVM_ARGS and LD_LIBRARY_PATH for JProfiler Debugging
-Xint -Xrunjprofiler:port=8849 -Xbootclasspath/a:/space/tools/jprofiler3/bin/agent.jar
and also
export LD_LIBRARY_PATH=/opt/jprofiler3/bin/linux-x86:$LD_LIBRARY_PATH

Adding Jars to your CLASSPATH in linux

export CLASSPATH=/space/mol.jar:$CLASSPATH
for j in $JMETER_HOME/lib/*.jar; do
CLASSPATH=$j:$CLASSPATH
echo $j
done


Note: This script initially adds the /space/mol.jar to the classpath.After than it adds all jars under the $JMETER_HOME/lib directory to the classpath.
