Model of the distributed stress test Apache Jmeter 3.3

Install Apache Jmeter 3.3 (both nodes)

• wget http://apache.dattatec.com//jmeter/binaries/apache-jmeter-3.3.tgz
• tar zxvf apache-jmeter-3.3.tgz
• mv apache-jmeter-3.3 jmeter-3.3
• jmeter-3.3/bin/jmeter –version

Edit the master node. The file is located in /jmeter-3.3/bin/jmeter.properties and in the section remote_hosts add the ip adress of the slave nodes.

Install the library so you can execute the Apache Jmeter in graphical mode (X11) (master node only)

• apt-get install libxtst6

Tunning of Jmeter

Edit the file and change the value

• vi /root/jmeter-3.3/bin/jmeter
• HEAP="-Xms512m -Xmx6144m"

Tunning Debian(both master and slave nodes)

Change in sysctl

Check the values in ip_local_port_range and then we change it

• cat /proc/sys/net/ipv4/ip_local_port_range= 32768 61000
• net.ipv4.ip_local_port_range = 10000 65000
• sysctl -p

Edit the file /etc/hosts (master node only)

127.0.0.1 localhost
192.168.1.101  str1 stresstest-app01 stresstest-prod-app01
192.168.1.102  str2 stresstest-app02 stresstest-prod-app02
192.168.1.103  str3 stresstest-app03 stresstest-prod-app03
192.168.1.104  str4 stresstest-app04 stresstest-prod-app04
192.168.1.105  str5 stresstest-app05 stresstest-prod-app05
192.168.1.106  str6 stresstest-app06 stresstest-prod-app06

Delete rpcbind package

• apt-get --purge remove rpcbind

Disable snmpd

• systemctl stop snmpd
• systemctl disable snmpd

Delete dependencies not used

• apt-get --purge autoremove

Distributed load in JMeter

Start the slave nodes in server mode

• cd /jmeter-3.3/bin/
• ./jmeter-server

In the graphical mode, generate the .jmx file for the test plan, save it, close the aplication, and then run the following command:

./jmeter.sh -n -t /root/test-plan/plan_test.jmx -l /root/results.jtl -j /root/runlog.log -r

• -n --nongui: run JMeter in console mode
• -t --testfile <argument>: this is the file with the extension .jmx that will use for the test
• -l --logfile <argument>: this file will save the log samples (.jtl)
• -j --jmeterlogfile <argument>: generate a log file (.log)
• -r --runremote: start the remote nodes (as was defined in the remote_hosts)

Once it is finished, run the graphical mode, create a Listener “Summary Report” to load the .jtl file, so you can analize the results.
