]> User's Manual: Properties Reference

This document describes JMeter properties. The properties present in jmeter.properties or reportgenerator.properties should be set in the user.properties file. These properties are only taken into account after restarting JMeter as they are usually resolved when the class is loaded.

Preferred GUI language. Comment out to use the JVM default locale's language.
Example: language=en This property is the only one that must be set in jmeter.properties file To fully configure language ensure you set locale, see Internationalization: Understanding Locale in the Java Platform. Example for English: -Duser.language=en -Duser.region=EN Additional locale(s) to add to the displayed list.
The current default list is: en, fr, de, no, es, tr, ja, zh_CN, zh_TW, pl, pt_BR.
See JMeterMenuBar#makeLanguageMenu()
The entries are a comma-separated list of language names.
Example: locales.add=zu
Path to a Properties file containing Namespace mapping in the form prefix=Namespace. Example: ns=http://biz.aol.com/schema/2006-12-18 XPath2 query cache for storing compiled XPath queries Defaults to 400
SSL (Java) System properties are now in system.properties
JMeter no longer converts javax.xxx property entries in jmeter.properties into System properties. These must now be defined in the system.properties file or on the command-line. The system.properties file gives more flexibility. By default, SSL session contexts are now created per-thread, rather than being shared.
The old behaviour can be enabled by setting this property to true. Defaults to: false Be aware that https default protocol may vary depending on the version of JVM. See Diagnosing TLS, SSL and HTTPS and 58236. Default HTTPS protocol level: https.default.protocol=TLS This may need to be changed to: https.default.protocol=SSLv3 List of protocols to enable. You may have to select only a subset if you find issues with target server.
This is needed when server does not support Socket version negotiation, this can lead to errors like: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated or java.net.SocketException: Connection reset.
See 54759, example: https.socket.protocols=SSLv2Hello SSLv3 TLSv1 Comma-separated list of SSL cipher suites that may be used in HTTPS connections. It may be desirable to use a subset of cipher suites in order to match expected client behavior or to reduce encryption overhead in JMeter when running with large numbers of users. Errors may occur if the JVM does not support the specified cipher suites, or if the cipher suites supported by the HTTPS server do not overlap this list. See the JSSE Reference Guide.
For example: https.cipherSuites=TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384,TLS_RSA_WITH_AES_128_GCM_SHA256 If not specified, JMeter will use the default list of cipher suites supported by the JVM. Reset HTTP State when starting a new Thread Group iteration. In summarytrue means next iteration is associated to a new user. false means next iteration is associated to same user. true involves:
  • Closing opened connection
  • resetting SSL State
Defaults to: true Control if we allow reuse of cached SSL context between iterations.
Set the value to false to reset the SSL context each iteration.
Defaults to: true DEPRECATED, you should use httpclient.reset_state_on_thread_group_iteration with correct value Start index to be used with keystores with many entries.
The default is to use entry 0, i.e. the first.
Defaults to: 0 End index to be used with keystores with many entries.
Defaults to: 0
Classname of the Swing default UI
The LAF classnames that are available are now displayed as ToolTip text when hovering over the Options/Look and Feel selection list.
You can either use a full class name, as shown below, or one of the strings "System" or "CrossPlatform" which means JMeter will use the corresponding string returned by UIManager.get<name>LookAndFeelClassName().
LAF can be overridden by os.name (lowercased, spaces replaced by '_').
Take for example an os.name of Windows 10.
JMeter would look first for a property jmeter.laf.windows_10=javax.swing.plaf.metal.MetalLookAndFeel Failing that, the OS family os.name would be used shortened to the first space. In our example JMeter would therefore look for a property jmeter.laf.windows=com.sun.java.swing.plaf.windows.WindowsLookAndFeel Mac apparently looks better with the System LAF set through jmeter.laf.mac=System Failing that, the JMeter default LAF can be defined through: jmeter.laf=System If none of the above jmeter.laf properties are defined, JMeter uses the CrossPlatform LAF. This is because the CrossPlatform LAF generally looks better than the System LAF. See 52026 for details. When you change Look and Feel (LAF) from JMeter GUI through menu Options > Look and Feel, you should restart JMeter to ensure change is fully effective. Display LoggerPanel.
Defaults to: false Enable LogViewer Panel to receive log event even when closed.
Enabled since 2.12
Note this has some impact on performances, but as GUI mode must not be used for Load Test it is acceptable Defaults to: true Max lines kept in LoggerPanel, 0 means no limit.
Defaults to: 1000 Interval period in ms to process the events of the listeners.
Defaults to: 500
Toolbar icon definitions.
Defaults to org/apache/jmeter/images/toolbar/icons-toolbar.properties Toolbar list.

Suggested value for HiDPI mode is jmeter.toolbar.icons.size=48x48 Defaults to: 22x22 Icon definitions. Alternate set: jmeter.icons=org/apache/jmeter/images/icon_1.properties Historical icon set (deprecated): jmeter.icons=org/apache/jmeter/images/icon_old.properties Defaults to:org/apache/jmeter/images/icon.properties Available sizes are: 19x19, 24x24, 32x32, 48x48. Useful for HiDPI display (see below).
Defaults to: 19x19
Suggested value for HiDPI screen like 3200x1800 is: 32x32 HiDPI mode. Activate a 'pseudo'-HiDPI mode. Allows to increase size of some UI elements which are not correctly managed by JVM with high resolution screens in Linux or Windows.
Defaults to: false HiDPI scale factor. Suggested value for HiDPI: 2.0. Defaults to: 1.0 Components to not display in JMeter GUI (GUI class name or static label).
These elements are deprecated and will be removed in next version: MongoDB Script, MongoDB Source Config Defaults to: org.apache.jmeter.protocol.mongodb.sampler.MongoScriptSampler, org.apache.jmeter.protocol.mongodb.config.MongoSourceElement Number of items in undo history.
Feature is disabled by default (0) due to known and not fixed bugs 57043, 57039 and 57040. Set it to a number greater than zero (25 can be a good default).
The bigger it is, the more memory will be consumed. Defaults to: 0 Hotkeys to add JMeter components where X is the shortcut key, for example: gui.quick_0=ThreadGroupGui gui.quick_1=HttpTestSampleGui gui.quick_2=RegexExtractorGui gui.quick_3=AssertionGui gui.quick_4=ConstantTimerGui gui.quick_5=TestActionGui gui.quick_6=JSR223PostProcessor gui.quick_7=JSR223PreProcessor gui.quick_8=DebugSampler gui.quick_9=ViewResultsFullVisualizer Above code will add the corresponding elements when you press Ctrl0 … Ctrl9 (&command;0 … &command;9 on Mac)
Enable auto backups of the .jmx file when a test plan is saved.
When enabled, before the .jmx is saved, it will be backed up to the directory pointed to by the jmeter.gui.action.save.backup_directory property (see below). Backup file names are built after the jmx file being saved. For example, saving test-plan.jmx will create a test-plan-000012.jmx in the backup directory provided that the last created backup file is test-plan-000011.jmx.
Default value is true indicating that auto backups are enabled.
Defaults to: true Set the backup directory path where JMX backups will be created upon save in the GUI.
If not set (what it defaults to) then backup files will be created in a sub-directory of the JMeter base installation. If set and the directory does not exist, a corresponding directory will be created.
Defaults to: ${JMETER_HOME}/backups Set the maximum time (in hours) that backup files should be preserved since the save time.
By default no expiration time is set which means we keep backups for ever.
Defaults to: 0 Set the maximum number of backup files that should be preserved. By default ten backups will be preserved.
Setting this to zero will cause the backups to not being deleted (unless keep_backup_max_hours is set to a non zero value).
Defaults to: 10 Enable auto saving of the .jmx file before start run a test plan
When enabled, before the run, the .jmx will be saved and also backed up to the directory pointed.
Defaults to: true
Remote Hosts - comma delimited, for example remote_hosts=localhost:1099,localhost:2010 Defaults to: 127.0.0.1 RMI port to be used by the server (must start rmiregistry with same port). To change the port to (say) 1234:
On the server(s):
  1. set server_port=1234
  2. start rmiregistry with port 1234
On Windows this can be done by: SET SERVER_PORT=1234 JMETER-SERVER On Unix: SERVER_PORT=1234 jmeter-server On the Windows client: set remote_hosts=server:1234 On the Unix client: export remote_hosts=server:1234 Defaults to: 1099 Parameter that controls the RMI port used by the RemoteSampleListenerImpl (The Controller)
Default value is 0, which means port is randomly assigned. You may need to open a port in the firewall on the Controller machine. Defaults to: 0 When distributed test is starting, there may be several attempts to initialize remote engines.
By default, only a single try is made. Increase this property to make it retry additional times.
Defaults to: 1 If initialization is retried, this property sets the delay between those attempts in milliseconds.
Defaults to: 5000 When all initialization tries were made, the test will fail, if any remote engines are failed.
Set this property to true to ignore failed nodes and proceed with test.
Defaults to: false To change the default port (1099) used to access the server.
Defaults to: 1099 To use a specific port for the JMeter server engine, define this property before starting the server.
Defaults to: 4000 From JMeter version 2.3.1, the JMeter server creates the RMI registry as part of the server process.
Set this property to false, to stop the server creating the RMI registry.
Defaults to: true From JMeter version 2.3.1, define this property to cause JMeter to exit after the first test.
Defaults to: true Type of keystore for RMI connection security. Possible values are dependent on the JVM in use, but commonly supported are JKS and PKCS12. Defaults to: JKS Keystore file that contains private key Defaults to: rmi_keystore.jks Password of Keystore Defaults to: changeit Key alias Defaults to: rmi Type of truststore for RMI connection security Defaults to: the value of server.rmi.ssl.keystore.type, which is JKS Keystore file that contains certificate Defaults to: the value of server.rmi.ssl.keystore.file, which is rmi_keystore.jks Password of Trust store Defaults to: the value of server.rmi.ssl.keystore.password, which is changeit Set this to true if you don't want to use SSL for RMI Defaults to: false

Uncomment this line if you put anything in hc.parameters file.
Defaults to: hc.parameters Preemptively send Authorization Header when BASIC auth is used Defaults to: true Number of retries to attempt. Retry will be done on Idempotent Http Methods by default. If you want to retry for all methods, see property httpclient4.request_sent_retry_enabled
Defaults to: 0 Set this property to true if it's OK to retry requests that have been sent. This mean that both Idempotent and non Idempotent requests will be retried. This should usually be false, but it can be useful when testing against some Load Balancers like Amazon ELB.
Defaults to: false Idle connection timeout (in milliseconds) to apply if the server does not send Keep-Alive timeout headers.
Defaults to: 0 (no suggested duration for Keep-Alived connections) Check connection if the elapsed time (in milliseconds) since the last use of the connection exceeds this value. Ensure this value is always lower by at least 150 ms than httpclient4.time_to_live
Defaults to: 1700 TTL (in milliseconds) represents an absolute value. No matter what, the connection will not be re-used beyond its TTL.

Defaults to: false If true, default HC4 User-Agent (Apache-HttpClient/X.Y.Z (Java/A.B.C_D)) will not be added.
Defaults to: false
Space or comma separated list of methods that can be cached.
Defaults to: GET N.B. This property is currently a temporary solution for 56162. Since version 2.12, JMeter does not create anymore a Sample Result with a response code of 204 for a resource found in cache. This is in line with what browser do.
You can choose between three modes:
RETURN_NO_SAMPLE (default)
this mode returns no Sample Result. It has no additional configuration.
RETURN_200_CACHE
this mode will return Sample Result with response code to 200 and response message to "(ex cache)".
RETURN_CUSTOM_STATUS
choosing this mode, response code and message have to be set by specifying RETURN_CUSTOM_STATUS.code and RETURN_CUSTOM_STATUS.message.
Defaults to: RETURN_NO_SAMPLE This lets you select what response code you want to return if mode RETURN_CUSTOM_STATUS is selected.
Defaults to empty value. This lets you select what response message you want to return if mode RETURN_CUSTOM_STATUS is selected.
Defaults to empty value
This section helps determine how result data will be saved.
The commented out values are the defaults.
Legitimate values: xml, csv, db.
Only xml and csv are currently supported.
Defaults to: csv true when field should be saved; false otherwise.
assertion_results_failure_message only affects CSV output.
Defaults to: true Legitimate values: none, first, all.
Defaults to: none Defaults to: true Defaults to: true Defaults to: true response_data is currently not supported for CSV output Defaults to: false Save ResponseData for failed samples. Defaults to: false Defaults to: true Defaults to: true Defaults to: true Defaults to: true Defaults to: true Defaults to: true Defaults to: true Defaults to: false Defaults to: false Defaults to: false Defaults to: false Defaults to: false Defaults to: true Defaults to: false Defaults to: false Defaults to: false Defaults to: true Defaults to: false Defaults to: true Timestamp format - this only affects CSV output files.
Legitimate values: none, ms, or a format suitable for SimpleDateFormat.
Defaults to: ms Defaults to: yyyy/MM/dd HH:mm:ss.SSS For use with Comma-separated value (CSV) files or other formats where the fields' values are separated by specified delimiters.
Defaults to: , For TAB, one can use \t Only applies to CSV format files:
Print field names as first line in CSV
Defaults to: true Optional list of JMeter variable names whose values are to be saved in the result data files.
Use commas to separate the names.
Defaults to: SESSION_ID,REFERENCE N.B. The current implementation saves the values in XML as attributes, so the names must be valid XML names. Versions of JMeter after 2.3.2 send the variable to all servers to ensure that the correct data is available at the client.
Optional XML processing instruction for line two of the file.
Defaults to empty value Prefix used to identify filenames that are relative to the current base.
Defaults to: ~/ AutoFlush on each line written in XML or CSV output.
Setting this to true will result in less test results data loss in case of a crash, but with impact on performances, particularly for intensive tests (low or no pauses).
Since JMeter version 2.10, this is false by default.
Defaults to: false
Save the start time stamp instead of the end.
This also affects the timestamp stored in result files.
Defaults to: true Whether to use System.nanoTime() - otherwise only use System.currentTimeMillis().
Defaults to: true Use a background thread to calculate the nanoTime offset.
Set this to a value less than zero to disable the background thread.
Defaults to: 5000 Since version 5.0 JMeter has a new SubResult Naming Policy which numbers subresults by default
This property if set to true discards renaming policy. This can be required if you're using JMeter for functional testing.
Defaults to: false
File that holds a record of name changes for backward compatibility issues.
Defaults to: /bin/upgrade.properties
N.B. The element was originally called the Proxy recorder, which is why the properties have the prefix "proxy". If the recorder detects a gap of at least 5s (default) between HTTP requests, it assumes that the user has clicked a new URL. Specified in milliseconds.

Defaults to: 7 Use dynamic key generation (if supported by JMeter/JVM).
If false, will revert to using a single key with no certificate.
Defaults to: true
Use command-line flags for user-name and password.
Defaults to: NTLM domain, if required by HTTPClient sampler
Space-separated list of parser groups.
For each parser, there should be a parser.types and a parser.className property Defaults to: htmlParser wmlParser cssParser CSS Parser based on ph-css.
Defaults to: org.apache.jmeter.protocol.http.parser.CssParser Content types handled by cssParser.
Defaults to: text/css CSS parser LRU cache size. This cache stores the URLs found in a CSS to avoid continuously parsing the CSS. By default the cache size is 400. It can be disabled by setting its value to 0.
Defaults to: 400 Let the CSS Parser ignore all CSS errors.
Defaults to: true Define the HTML parser to be used.
Do not comment this property.
org.apache.jmeter.protocol.http.parser.LagartoBasedHtmlParser

org.apache.jmeter.protocol.http.parser.JTidyHTMLParser
Default parser before JMeter version 2.10
org.apache.jmeter.protocol.http.parser.RegexpHTMLParser
Note that Regexp extractor may detect references that have been commented out. In many cases it will work OK, but you should be aware that it may generate additional references.
org.apache.jmeter.protocol.http.parser.JsoupBasedHtmlParser
This parser is based on JSoup. It should be the most accurate parser, but it is less performant than LagartoBasedHtmlParser
Defaults to: org.apache.jmeter.protocol.http.parser.LagartoBasedHtmlParser Used by HTTPSamplerBase to associate htmlParser with content types below.
Defaults to: text/html application/xhtml+xml application/xml text/xml Defaults to: org.apache.jmeter.protocol.http.parser.RegexpHTMLParser Used by HTTPSamplerBase to associate wmlParser with content types below.
Defaults to: text/vnd.wap.wml

Configure how SampleResults are sent from server to client when using distributed testing.

Note that the mode is currently resolved on the client, while other properties (e.g. time_threshold) are resolved on the server.

Since JMeter version 2.9, default is StrippedBatch, which returns samples in batch mode (every 100 samples or every minute by default).
You can set mode by configuring:

mode=one of the possible modes below StrippedBatch strips response data from SampleResult, so if you need the response data, change to another mode.

Possible modes are:

Standard
Sends SampleResult one by one
Batch
Accumulates SampleResults before sending them. Configured by properties num_sample_threshold and time_threshold
Statistical
returns sample summary statistics. Configured by properties key_on_threadname and time_threshold
Stripped
Similar to Standard mode but strips Response from SampleResult. Configured by property sample_sender_strip_also_on_error
StrippedBatch
Same as Batch but strips Response from SampleResult. Configured by properties num_sample_threshold, time_threshold and sample_sender_strip_also_on_error
Asynch
Asynchronous sender; uses a queue and background worker process to return the samples. Configured by property asynch.batch.queue.size
StrippedAsynch
Same as Asynch but strips response data from SampleResult. Configured by properties asynch.batch.queue.size and sample_sender_strip_also_on_error
StrippedDiskStore
Same as DiskStore but strips response data from SampleResult
Class extending AbstractSampleSender (org.example.load.MySampleSender for example)

Defaults to: true Remote batching support.
Since JMeter version 2.9, default is StrippedBatch, which returns samples in batch mode (every 100 samples or every minute by default).

Do not use this for utility or plugin dependency jars.
Defaults to empty value. List of directories that JMeter will search for utility and plugin dependency classes.
Use your platform path separator (java.io.File.pathSeparatorChar in Java) to separate multiple paths.
Any jar file in such a directory will be automatically included; jar files in sub directories are ignored.
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.
Paths with spaces may cause problems for the JVM.
Defaults to empty value. List of directories (separated by ;) that JMeter will search for utility and plugin dependency classes.
Any jar file in such a directory will be automatically included; jar files in sub directories are ignored.
The given value is in addition to any jars found in the lib directory or given by the user.classpath property.
All entries will be added to the path of the JMeter internal loader only.
For plugin dependencies this property should be used instead of user.classpath.
Defaults to empty value. The classpath finder currently needs to load every single JMeter class to find the classes it needs.
For CLI mode, it's only necessary to scan for Function classes, but all classes are still loaded.
All current Function classes include ".function." in their name, and none include ".gui." in the name, so the number of unwanted classes loaded can be reduced by checking for these. However, if a valid function class name does not match these restrictions, it will not be loaded. If problems are encountered, then comment or change this or the following property.
Defaults to: .functions. Defaults to: .gui.
