Jmeter分布式性能测试详解（3）监听器配置

## 监听器配置-记录非GUI测试结果 ##

实际测试命令行：

jmeter -n -t testplan.jmx -l testplan\_01.jtl -j testplan\_01.log -Jprop=value -Jprop2=value2  
xml格式能让命令行测试后保存详细信息，csv格式不够详细，具体看jmeter.properties配置。  
通过启动时设置jmeter监听测试数据，例如  
\-Jjmeter.save.saveservice.output\_format=xml  
\-Jjmeter.save.saveservice.assertion\_results\_failure\_message =true  
\-Jjmeter.save.saveservice.response\_data.on\_error=true  
\-Jjmeter.save.saveservice.samplerData=true  
\-Jjmeter.save.saveservice.responseHeaders=true  
\-Jjmeter.save.saveservice.requestHeaders=true

## 监听器配置-记录非GUI测试结果 ##

在非GUI模式下运行时为每次测试运行指定不同的数据和日志文件，例如：

jmeter -n -t testplan.jmx -l testplan\_01.jtl -j testplan\_01.log  
jmeter -n -t testplan.jmx -l testplan\_02.xml -j jmeter\_’yyyyMMddHHmmss’.log

日志文件中’yyyyMMddHHmmss’按前日期的SimpleDateFormat格式进行处理

## jmeter.properties（或user.properties）配置结果文件格式 ##

可设置结果文件类型为cvs或者xml格式，cvs文件格式以逗号分隔，也可以制定分隔符。

要更改默认格式，请在jmeter.properties中找到以下行：  
jmeter.save.saveservice.output\_format = csv  
jmeter.save.saveservice.assertion\_results\_failure\_message =true  
jmeter.save.saveservice.default\_delimiter = |

以下是有关监听器配置：

#---------------------------------------------------------------------------
    # Results file configuration
    #---------------------------------------------------------------------------
    
    # 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.
    #jmeter.save.saveservice.output_format=csv
    
    
    # true when field should be saved; false otherwise
    
    # assertion_results_failure_message only affects CSV output
    #jmeter.save.saveservice.assertion_results_failure_message=true
    #
    # legitimate values: none, first, all
    #jmeter.save.saveservice.assertion_results=none
    #
    #jmeter.save.saveservice.data_type=true
    #jmeter.save.saveservice.label=true
    #jmeter.save.saveservice.response_code=true
    # response_data is not currently supported for CSV output
    #jmeter.save.saveservice.response_data=false
    # Save ResponseData for failed samples
    #jmeter.save.saveservice.response_data.on_error=false
    #jmeter.save.saveservice.response_message=true
    #jmeter.save.saveservice.successful=true
    #jmeter.save.saveservice.thread_name=true
    #jmeter.save.saveservice.time=true
    #jmeter.save.saveservice.subresults=true
    #jmeter.save.saveservice.assertions=true
    #jmeter.save.saveservice.latency=true
    #jmeter.save.saveservice.connect_time=true
    #jmeter.save.saveservice.samplerData=false
    #jmeter.save.saveservice.responseHeaders=false
    #jmeter.save.saveservice.requestHeaders=false
    #jmeter.save.saveservice.encoding=false
    #jmeter.save.saveservice.bytes=true
    #jmeter.save.saveservice.sent_bytes=true
    #jmeter.save.saveservice.url=false
    #jmeter.save.saveservice.filename=false
    #jmeter.save.saveservice.hostname=false
    #jmeter.save.saveservice.thread_counts=true
    #jmeter.save.saveservice.sample_count=false
    #jmeter.save.saveservice.idle_time=true
    
    # Timestamp format - this only affects CSV output files
    # legitimate values: none, ms, or a format suitable for SimpleDateFormat
    #jmeter.save.saveservice.timestamp_format=ms
    #jmeter.save.saveservice.timestamp_format=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.
    # Default:
    #jmeter.save.saveservice.default_delimiter=,
    # For TAB, since JMeter 2.3 one can use:
    #jmeter.save.saveservice.default_delimiter=\t
    
    # Only applies to CSV format files:
    # Print field names as first line in CSV
    #jmeter.save.saveservice.print_field_names=true
    
    # Optional list of JMeter variable names whose values are to be saved in the result data files.
    # Use commas to separate the names. For example:
    #sample_variables=SESSION_ID,REFERENCE
    # N.B. The current implementation saves the values in XML as attributes,
    # so the names must be valid XML names.
    # JMeter sends the variable to all servers
    # to ensure that the correct data is available at the client.
    
    # Optional xml processing instruction for line 2 of the file:
    #jmeter.save.saveservice.xml_pi=<?xml-stylesheet type="text/xsl" href="sample.xsl"?>
    
    # Prefix used to identify filenames that are relative to the current base
    #jmeter.save.saveservice.base_prefix=~/
    
    # 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 Crash
    # but with impact on performances, particularly for intensive tests (low or no pauses)
    # Since JMeter 2.10, this is false by default
    #jmeter.save.saveservice.autoflush=false
    
    # Put the start time stamp in logs instead of the end
    sampleresult.timestamp.start=true
    
    # Whether to use System.nanoTime() - otherwise only use System.currentTimeMillis()
    #sampleresult.useNanoTime=true
    
    # Use a background thread to calculate the nanoTime offset
    # Set this to <= 0 to disable the background thread
    #sampleresult.nanoThreadSleep=5000

## GUI界面监听器的值 ##

对应这些配置在GUI界面可以选择，但非GUI运行测试用例下，需要在配置文件根据自己需求修改进行配置，或者执行jmeter时候制定-Jprop=val来制定监听器的值
