Jmeter apache user manual

We recommend that most users run the latest release. If you do not mind working with beta-quality software, then you can download and run the latest nightly build. Then, open a shell or command prompt and change to JMeter's top-level directory. Next, type "build install". To run JMeter, run the jmeter.

JMeter will automatically find JMeter components in any jars found here. To do so, run the jmeter. Java system properties, JMeter properties, and logging properties can be overriden directly on the command line instead of modifying jmeter. The -L flag can also be used without the category name to set the root logging level. Examples : jmeter -Duser. The command line properties are processed early in startup, but after the logging system has been set up.

If JMeter detects an error, a message will be written to the log file. The log file name is defined in the jmeter. It is normally defined as jmeter. When running on Windows, the file may appear as just jmeter unless you have set Windows to show file extensions. JMeter: Version 1. StandardJMeterEngine: Running the test! StandardJMeterEngine: Test has ended The log file can be helpful in determining the cause of an error, as JMeter does not interrupt a test to display an error dialogue.

It defaults to jmeter. 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. The jmeter scripts that take a test plan name as a parameter e.

When running on Windows, the file may appear as just jmeter unless you have set Windows to show file extensions. As well as recording errors, the jmeter. For example:. The log file can be helpful in determining the cause of an error, as JMeter does not interrupt a test to display an error dialogue. Invoking JMeter as "jmeter -? These are shown below. Note: the JMeter log file name is formatted as a SimpleDateFormat applied to the current date if it contains paired single-quotes,.

If the special name LAST is used for the -t, -j or -l flags, then JMeter takes that to mean the last test plan that was run in interactive mode.

Prior to version 2. This caused problems for applications that invoke JMeter directly, so JMeter no longer invokes System. To detect this situation, JMeter starts a new daemon thread just before it exits. This daemon thread waits a short while; if it returns from the wait, then clearly the JVM has not been able to exit, and the thread prints a message to say why.

The property jmeter. If set to 0, then JMeter does not start the daemon thread. If you wish to modify the properties with which JMeter runs you need to either modify the jmeter. The file will be automatically loaded if it is found in the current directory or if it is found in the JMeter bin directory.

Similarly, system. Parameters Attribute Description Required ssl. No xml. The default value is: org. If you are running JMeter in a distributed environment, list the machines where you have JMeter remote servers running.

As JMeter has more and more components added, you may wish to customize your JMeter to show only those components you are interested in. You may list their classname or their class label the string that appears in JMeter's UI here, and they will no longer appear in the menus. A path item can either be a jar file or a directory. No user. Use your platform path separator to separate multiple paths. Any jar file in such a directory will be automatically included in user. The given value is in addition to any jars found in the lib directory.

All entries will be added to the class path of the system class loader and also to the path of the JMeter internal loader. The given value is in addition to any jars found in the lib directory or given by the user. All entries will be added to the path of the JMeter internal loader only.

These are added after the initial property file, but before the -q and -J options are processed. No system. These are added before the -S and -D options are processed. The command line options and properties files are processed in the following order: -p propfile jmeter. See also the comments in the jmeter. JMeter: Version 1. You could add assertions to check for certain HTML tags, common error strings, and so on.

JMeter lets you create these assertions using regular expressions. JMeter's built-in samplers. Listeners provide access to the information JMeter gathers about the test cases while JMeter runs. The simplest listener, the Graph Results listener plots the response times on a graph. Listeners provide a graphical view of the data that JMeter generates.

Additionally, listeners can direct the data they collect to a file for later use. Every listener in JMeter provides a field to indicate the file to store data to. Listeners can be added anywhere in the test. They will collect data only from elements at or below their level. There are several interesting listeners that come with JMeter. By default, a JMeter thread sends requests without pausing between each request.

We recommend that you specify a delay by adding one of the available timers to your Thread Group. If you do not add a delay, JMeter could overwhelm your server by making too many requests in a very short amount of time. The timer will cause JMeter to delay a certain amount of time between each request that a thread makes.

If you choose to add more than one timer to a Thread Group, JMeter takes the sum of the timers and pauses for that amount of time. Assertions allow you to assert facts about responses received from the server being tested. Using an assertion, you can essentially "test" that your application is returning the results you expect it to.

For instance, you can assert that the response to a query will contain some particular text. The text you specify can be a Perl-style regular expression, and you can indicate that the response is to contain the text, or that it should match the whole response.

You can add an assertion to any Sampler. If JMeter cannot find the text, then it will mark this as a failed request. To view the assertion results, add an Assertion Listener to the Thread Group. A configuration element works closely with a Sampler.

A configuration element is accessible from only inside the tree branch where you place the element. Also, a configuration element inside a tree branch has higher precedence than the same element in a "parent" branch. A Pre-Processor executes some action prior to a Sampler Request being made. If a Pre-Processor is attached to a Sampler element, then it will execute just prior to that sampler element running.

A Pre-Processor is most often used to modify the settings of a Sample Request just before it runs, or to update variables that aren't extracted from response text.

See the scoping rules for more details on when Pre-Processors are executed. A Post-Processor executes some action after a Sampler Request has been made. If a Post-Processor is attached to a Sampler element, then it will execute just after that sampler element runs. A Post-Processor is most often used to process the response data, often to extract values from it. Evaluate Confluence today.
