Stress testing tool Apache JMeter: 9: distributed test environment dynamically assigned node

Original: stress test tool Apache JMeter: 9: distributed test environment dynamically assigned node

Apache JMeter is a pure Java open-source software for load testing or performance testing. Describes a method and JMeter building distributed test environment used in the previous article, but after a main multi-pressure measurement from the environment, and is specified by the pages in the demo manner, with specific examples of the article to explain how to use the command line to dynamically specify the node, because the integration JMeter of time, this manual operation requires the use of an automatic way to replace, but the command line directly provides the option to be supported.

JMeter distributed pressure test environment preparation

Detailed construction method with reference to the following environment:

• https://blog.csdn.net/liumiaocn/article/details/101638943

The results confirmed

Start command: jmeter -Djava.rmi.server.hostname = machine name or IP address of the -Dserver_port = port number -s -j log file name

Prepared in advance of the start Slave nodes only need to set aside three of JMeter, there will be three inactive after starting the process JMeter

Pressure test preparation application (nginx service)

Pressure sensing applications:
http://192.168.31.242:8088/

In use port 8088 starts a Docker application Nginx local machine (in other ways may also be used), example is shown below:

liumiaocn:~ liumiao$ docker images |grep nginx |grep latest
nginx                                           latest                          e445ab08b2be        2 months ago        126MB
liumiaocn:~ liumiao$ docker run -p 8088:80 -d --name=nginx-test nginx:latest
