I have added full device information in CSV file and here device information:
{"IpAddress":"fec0::15:b2ff:fe00:0fec0::ac6b:8271:fa94:818c192.168.232.2fec0::10bf:85ff:fe05:9ec1fec0::a1f6:b9e4:fd47:4b15192.168.200.2","BuildVersion":"1.0","DeviceManufacturer":"Google","DeviceOS":"android","DeviceVersion":"28","IMEINumber":"358240051111110","NetworkCountryISO":"us","PhoneNumber":"","SIMCountryISO":"us","SIMSerialID":"89014103211118510720","SIMState":"5","UUIDNumber":"eda5b585a146e41d"}
which I passed in a CSV and when I run this code every time it's give me error because full device info is not passing. Please help me how to solve this issue.
Thank You.
CSV stands for comma-separated values and there are 11 commas in your "full device info" so the options are in:
Change the "delimiter" in the CSV Data Set Config to some character which is not present in your test data, for example |
Use __StringFromFile() function which reads the next line from the file each time it's being called directly in the relevant Sampler

To achieve:- To send the below-mentioned string to a server every 10 secs.
Text to Send:- '''XXXXXXX,XXXXXXX,XXXXXXXX,${packettype},${msgid},${pcktsts},${__threadGroupName},TSXXTSXXXX,${gpsfix},31082022,${__groovy(new Date().format("HHmmss", TimeZone.getTimeZone('UTC')),)},${lat},${latdir},${long},${longdir},${speed},${head},${sat},${alt},${pdop},${hdop},${network},${ignsts},${mpsts},${mivolt},${ibvoltusg},${emsts},${tampalt},31,404,86,7b73,b74a,86,02a2,7b73,49,4d0a,7d0b,49,1948,7b73,59,Ffff,0000,100000,001,${frame},0.0,0.0,${ddist},()*${checksum}'''
Here in the above text, I want the variables to be replaced automatically on every request with the data pre-defined (against that particular variable) in a CSV file.
Note:- I want to send the above data/string through a TCP Sampler.
Suggestions are appreciated if someone could suggest a better way of achieving the same.
If you have a variable from the CSV file which contains references to other JMeter Variables or functions you need to wrap it into __eval() function
For example:
You have foo variable with the value of bar
You have entry in the CSV file which looks like ${foo}
You defined some-variable in the CSV Data Set Config which returns this ${foo} entry from the file
then:
${some-variable} will return ${foo}
and ${__eval(${some-variable})} will return bar

I want to fetch order id from a variable in loop and store them in txt file separated with a comma(eg:"12345,12346,12347) and then use all the values in one go.
I am getting following error while running the script :
**Error in method invocation: Method setout( java.io.PrintStream ) not found in class'bsh.Interpreter'
**'
This is the variable ordid which i am storing in file
Also it is creating the file in my system but giving error
code i used to create a file
You have a typo in your code, I believe it should be setOut
Since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting
If you will execute your script with > 1 virtual user you will run into the race condition as when 2 or more threads will be writing into the same file it will result in data corruption so consider using i.e. Flexible File Writer for storing the data
For each sampler result I have a variable value which I want to show it in the summary report as a test result. How to write this value in the jtl file and show it in the summary report?
You can write the variable into a file using sample_variables property.
Add the next line to user.properties file:
sample_variables=foo
replace foo with your actual variable name
Restart JMeter to pick the property up
That's it, an extra column will be added to the .jtl results file holding the foo variable value for each SampleResult
With regards to displaying it in the summary report, this is not something you can do out of the box, however you can plot the variable value as a chart in the HTML Reporting Dashboard. If this is something you're interested in - add the next lines to user.properties file:
jmeter.reportgenerator.graph.custom_testGraph.classname=org.apache.jmeter.report.processor.graph.impl.CustomGraphConsumer
jmeter.reportgenerator.graph.custom_testGraph.title=Foo values
jmeter.reportgenerator.graph.custom_testGraph.property.set_Y_Axis=Foo values
jmeter.reportgenerator.graph.custom_testGraph.set_X_Axis=Over Time
jmeter.reportgenerator.graph.custom_testGraph.property.set_granularity=60000
jmeter.reportgenerator.graph.custom_testGraph.property.set_Sample_Variable_Name=foo
jmeter.reportgenerator.graph.custom_testGraph.property.set_Content_Message=Foo value :
again, replace foo with your actual JMeter Variable name

During my JMeter test I am extracting a float value from the response message an saving it to a variable using Regular Expression Extractor, and I am also saving that value in the generated test result csv file. Now I want to be able to generate a graph of this extracted float value, but haven't figured out a way to do so, or have found and examples to create my own graph plug in to graph this value.
In next version of JMeter 5.0, you’ll be able to do that bu adding in user.properties this:
sample_variables=VarName
jmeter.reportgenerator.graph.custom_mm_hit.classname=org.apache.jmeter.report.processor.graph.impl.CustomGraphConsumer
jmeter.reportgenerator.graph.custom_mm_hit.title=Graph Title
jmeter.reportgenerator.graph.custom_mm_hit.property.set_Y_Axis=Response Time (ms)
jmeter.reportgenerator.graph.custom_mm_hit.property.set_X_Axis=Over Time
jmeter.reportgenerator.graph.custom_mm_hit.property.set_granularity=${jmeter.reportgenerator.overall_granularity}
jmeter.reportgenerator.graph.custom_mm_hit.property.setSampleVariableName=VarName
jmeter.reportgenerator.graph.custom_mm_hit.property.setContentMessage=Message for graph point label
In above example:
VarName is the name of your variable
custom_mm_hit would be a unique id for your graph, you should change it but always prefix with "custom_"
To configure and generate graph see:
https://jmeter.apache.org/usermanual/generating-dashboard.html
You ‘ll get a new Graph of value over time in Custom Graphs section.
To download nightly build which is stable snd will be very close to 5.0, see:
https://jmeter.apache.org/nightly.html
You can use Sample Variables property to save your float value into .jtl results file
Add the next line to user.properties file:
sample_variables=foo
Replace foo with your actual JMeter Variable Reference Name from the Regular Expression Extractor
When you run your test next time you will see an extra column in the .jtl results file holding your float variable value. Another option is setting this property via -J command-line argument like
jmeter -Jsample_variables=foo -n -t test.jmx -l result.jtl
See Configuring JMeter and Apache JMeter Properties Customization Guide articles for more information on tuning your JMeter engine using properties.
Once you get the value stored you can plot the chart using LibreOffice Calc or Microsoft Excel or equivalent.
If you want to come up with a plugin to plot the custom variable you can start with How to write a plugin for JMeter guide and then look into source of i.e. Latencies Over Time plugin which lives in GitHub
How do i generate the results CSV ,jtl files automatically with the date and time format?
Basically what i am trying to looking for generating the Test results files CSV and jtl files automatically with the date and time stamp and pass that results file in the Graphs Generator , so that I don't need to keep modify the jmx files.If possible Graphs output folder also with the date and time stamp.
How do I achieve this?
