# 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
#locales.add=zu


#---------------------------------------------------------------------------
# XML Parser
#---------------------------------------------------------------------------

# Path to a Properties file containing Namespace mapping in the form
# prefix=Namespace
# Example:
# ns=http://biz.aol.com/schema/2006-12-18
#xpath.namespace.config=

#---------------------------------------------------------------------------
# SSL configuration
#---------------------------------------------------------------------------

## SSL System properties are now in system.properties

# JMeter no longer converts javax.xxx property entries in this file 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 original behaviour can be enabled by setting the JMeter property to true
#https.sessioncontext.shared=false

# Be aware that https default protocol may vary depending on the version of JVM
# See https://blogs.oracle.com/java-platform-group/entry/diagnosing_tls_ssl_and_https
# See https://bz.apache.org/bugzilla/show_bug.cgi?id=58236
# Default HTTPS protocol level:
#https.default.protocol=TLS
# This may need to be changed here (or in user.properties) 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:
# javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
# java.net.SocketException: Connection reset
# see https://bz.apache.org/bugzilla/show_bug.cgi?id=54759
#https.socket.protocols=SSLv2Hello SSLv3 TLSv1

# Control if we allow reuse of cached SSL context between iterations
# set the value to 'false' to reset the SSL context each iteration
#https.use.cached.ssl.context=true

# Start and end index to be used with keystores with many entries
# The default is to use entry 0, i.e. the first
#https.keyStoreStartIndex=0
#https.keyStoreEndIndex=0

#---------------------------------------------------------------------------
# Look and Feel configuration
#---------------------------------------------------------------------------

#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 '_')
# Sample os.name LAF:
#jmeter.laf.windows_xp=javax.swing.plaf.metal.MetalLookAndFeel

# Failing that, the OS family = os.name, but only up to first space:
# Sample OS family LAF:
#jmeter.laf.windows=com.sun.java.swing.plaf.windows.WindowsLookAndFeel

# Custom settings for Mac using System LAF if you don't want to use Darcula
#jmeter.laf.mac=System

# Failing that, the JMeter default laf can be defined:
#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 https://bz.apache.org/bugzilla/show_bug.cgi?id=52026 for details
# N.B. the laf can be defined in user.properties.

# LoggerPanel display
# default to false
#jmeter.loggerpanel.display=false

# Enable LogViewer Panel to receive log event even if 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
#jmeter.loggerpanel.enable_when_closed=true

# Max lines kept in LoggerPanel, default to 1000 chars
# 0 means no limit
#jmeter.loggerpanel.maxlength=1000

# Interval period in ms to process the queue of events of the listeners
#jmeter.gui.refresh_period=500

# HiDPI mode (default: false)
# 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
#jmeter.hidpi.mode=false
# To enable pseudo-hidpi mode change to true
#jmeter.hidpi.mode=true
# HiDPI scale factor
#jmeter.hidpi.scale.factor=1.0
# Suggested value for HiDPI
#jmeter.hidpi.scale.factor=2.0

#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
#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
#jmeter.gui.action.save.backup_on_save=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. The default directory is ${JMETER_HOME}/backups
#If set and the directory does not exist, it will be created.
#jmeter.gui.action.save.backup_directory=

#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.
#jmeter.gui.action.save.keep_backup_max_hours=0

#Set the maximum number of backup files that should be preserved. By default 10 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)
#jmeter.gui.action.save.keep_backup_max_count=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

#remote_hosts=localhost:1099,localhost:2010

# RMI port to be used by the server (must start rmiregistry with same port)
#server_port=1099

# To change the port to (say) 1234:
# On the server(s)
# - set server_port=1234
# - 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 client:
# - set remote_hosts=server:1234

# Parameter that controls the RMI port used by RemoteSampleListenerImpl (The Controller)
# Default value is 0 which means port is randomly assigned
# You may need to open Firewall port on the Controller machine
#client.rmi.localport=0

# When distributed test is starting, there may be several attempts to initialize
# remote engines. By default, only single try is made. Increase following property
# to make it retry for additional times
#client.tries=1

# If there is initialization retries, following property sets delay between attempts
#client.retries_delay=5000

# When all initialization tries was made, test will fail if some remote engines are failed
# Set following property to true to ignore failed nodes and proceed with test
#client.continue_on_fail=false

# To change the default port (1099) used to access the server:
#server.rmi.port=1234

# To use a specific port for the JMeter server engine, define
# the following property before starting the server:
#server.rmi.localport=4000

# The jmeter server creates by default the RMI registry as part of the server process.
# To stop the server creating the RMI registry:
#server.rmi.create=false

# Define the following property to cause JMeter to exit after the first test
#server.exitaftertest=true

# Those mode have the following behaviours:
# RETURN_NO_SAMPLE:
# 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)", you can modify response message by setting
# RETURN_200_CACHE.message=(ex cache)

# RETURN_CUSTOM_STATUS:
# This mode lets you select what response code and message you want to return,
