Apache Jmeter
Joelle Ridgeway
JMeter comes with Apache's Xerces XML parser. You have the option of telling JMeterto use a different XML parser. To do so, include the classes for the third-party parser in JMeter's classpath,and update the jmeter.properties file with the full classname of the parserimplementation.
The installation directory structure should look something like this (where X.Y is version number):apache-jmeter-X.Yapache-jmeter-X.Y/binapache-jmeter-X.Y/docsapache-jmeter-X.Y/extrasapache-jmeter-X.Y/lib/apache-jmeter-X.Y/lib/extapache-jmeter-X.Y/lib/junitapache-jmeter-X.Y/licensesapache-jmeter-X.Y/printable_docsYou can rename the parent directory (i.e. apache-jmeter-X.Y) if you want, but do not change any of the sub-directory names.
To run JMeter, run the jmeter.bat (for Windows) or jmeter (for Unix) file.These files are found in the bin directory.After a short time, the JMeter GUI should appear.GUI mode should only be used for creating the test script, CLI mode (NON GUI) must be used for load testing
It may be necessary to set a few environment variables to configure the JVM used by JMeter. Those variables can be either set directly in the shell starting the jmeter script. For example setting the variable JVM_ARGS will override most pre-defined settings, for example
To set those variables permanently, you can place them in a file called setenv.sh in the bin directory. This file will be sourced when running JMeter by calling the jmeter script. An example for bin/setenv.sh could look like:
If you are testing from behind a firewall/proxy server, you may need to provide JMeter withthe firewall/proxy server hostname and port number. To do so, run the jmeter[.bat] filefrom a command line with the following parameters:
For distributed testing, run JMeter in server mode on the remote node(s), and then control the server(s) from the GUI.You can also use CLI mode to run remote tests.To start the server(s), run jmeter-server[.bat] on each server host.
So, if you want to change the log level for org.apache.http category to debug level for instance, you can simply add (or uncomment) the following logger element in log4j2.xml file before launching JMeter.
If JMeter detects an error during a test, a message will be written to the log file. The log file name is defined in the log4j2.xml file (or using the -j option, see below). It defaults to jmeter.log, and will be found in the directory from which JMeter was launched.
The command-line option -j jmeterlogfile allow to process after the initial properties file is read, and before any further properties are processed. It therefore allows the default of jmeter.log to be overridden. The jmeter scripts that take a test plan name as a parameter (e.g. jmeter-n.cmd) have been updated to define the log file using the test plan name, e.g. for the test plan Test27.jmx the log file is set to Test27.log.
The property jmeter.exit.check.pause can be used to configure the delay before printing non-daemon threads.If set to 0 (default value), then JMeter does not print non-terminated threads at the end of the test.
If you wish to modify the properties with which JMeter runs you need to either modify the user.properties in the /bin directory or create your own copy of the jmeter.properties and specify it in the command line.
The command line options and properties files are processed in the following order:
- -p propfile
- jmeter.properties (or the file from the -p option) is then loaded
- -j logfile
- Logging is initialised
- user.properties is loaded
- system.properties is loaded
- all other command-line options are processed
I installed apache-jmeter-5.1.1 and java 1.8.0_221 (8), and was walking through the getting started guide to build a web test plan in the GUI. But when I click save to save the Test Plan I receive the below error:
An error occurred: The file C:\Users\xxxxx\Downloads\apache-jmeter-5.5\apache-jmeter-5.5\bin\templates\LoginPage.jmx -l C:\Users\xxxxx\Documents\Results\Jmeter.csv -e -o C:\Users\xxxxx\Documents\Results\report.csv doesn't exist or can't be opened

I am new to jmeter. I successfully installed jmeter into my windows machine. I opened "jmeter.bat" under apache-jmeter-4.0\bin. But the jmeter window is not showing the workbench section in the left panel. I have attached the screenshot below in the ApacheJmeter.
defiantly jmeter is best tool to automate rest apis. jmeter CSV approach helps to automate apis quickly. jmeter plus maven: adding jmeter maven plugin helps to integrate rest api test cases to build and this provides nice HTML interactive report to publish the results.
