I've put connection configuration into a csv data set so we can load a different configuration on different environments.
I've put the CSV Data Set Config as the first element under my test plan, with shared mode for all threads.
I've added the Debug Sampler to see if the content of the csv is parsed correctly and I'm seeing it ok. Even though, as u can see in the screenshot, is failing to resolve the variables when they are used?
I've also tried to put manually the Variable Names but I get the same response.
You need to show your CSV file (at least first 2 lines) and Debug Sampler output in order to get comprehensive help
Can it be a typo like the variable is ${CONTEXT_FACTORY} and you're having it as ${CONTEX_FACTORY}?
If your CSV file have header row with the variable names - set "Ignore first line" to False, otherwise you need to provide the variable names, one per "column"
On a one-liner like some context factory the following setup should work:

I am using the flexible file writer in Jmeter to write the four variables that I have captured and defined in the properties file. I have used the debug sampler to verify and view results of the values of each of the 4 variables that I have used.
But when I am trying to use number of threads as more than 3 or 5, I am getting garbled and multiple values of the variables in the same column of the output csv as:
But ideally I am expecting the result to be like:
Timestamp_Queued|Timestamp_Download_Started|Timestamp_Download_Completed|Timestamp_Completed
1623596826050 1623596829514 1623596829868 1623596830045
1623596826195 1623596826434 1623596826840 1623596827071
1623596826427 1623596827736 1623596828138 1623596828319
1623596826629 1623596830096 1623596830417 1623596830600
1623596826809 1623596827113 1623596827514 1623596827692
Can someone help please. I have tried using other JS to capture the data one below the other but I am not able to capture the data in the above way. I am sure Jmeter must have an easy way to accomplish this.
Thanks!
We cannot help you by looking at the screenshot of the result file, we need to see your configuration of the flexible file writer, know how do you launch your JMeter script, is there any suspicious entries in jmeter.log file, etc.
Given that:
You declare your variables as Sample Variables
Configure the Flexible File Writer to save these variables as variable#0,variable#1,etc
Run JMeter in command-line non-GUI mode
You should get the anticipated results

I am new to JMeter, I am trying to perform a sample test on an API, I am using CSV to get 'id' to be passed in the request body, I wanted to store all performance-related data in a CSV file, I came across plugin Flexible File Writer, the problem I am facing it write only txt file I wanted to desire data in CSV file is it possible and also needed to get one value from the response and 'id' that is been present in CSV file from where I am taking the input to store along with the result, the reason I need to know which request has taken most time.
Thanks
Irrespective of the listener, you can define a list of JMeter variables that will be written to the file in the JMeter property sample_variables.
https://jmeter.apache.org/usermanual/listeners.html#sample_variables
JMeter supports the sample_variables property to define a list of additional JMeter variables which are to be saved with each sample in the JTL files. The values are written to CSV files as additional columns, and as additional attributes in XML files. See above for an example.
# 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
So, in order to write your id to the csv file you could start JMeter with
jmeter -J sample_variables=id
which works without the Flexible File Writer, and for CSV as well as XML output format.
CSV is a subset of text file:
A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values.
so your "desire" is very unclear as the format of the file produced by the Flexible File Writer is totally up to you, for example here is default configuration changed from tab-separated to comma-separated:
And textual representations:
endTimeMillis,responseTime,latency,sentBytes,receivedBytes,isSuccessful,responseCode,id
endTimeMillis|,|responseTime|,|latency|,|sentBytes|,|receivedBytes|,|isSuccessful|,|responseCode|,|variable#0
With regards to this last column, you need to define a Sample Variable like:
sample_variables=id
in user.properties file (lives in "bin" folder of your JMeter installation)

I was trying to read csv file using csvdata config element in jmeter so as to test multiple logins but when I try to read the value from csv file then I get inverted commas appended with respect to result. Please tell me how to get rid of these commas being passed in the request parameters
Please find my csv data config and excel file and request parameter screenshot in attachments
JMeter normally doesn't add anything to the variables, most probably you have the quotation marks in the generated CSV file, open it with normal text editor like Notepad and use find-and-replace feature to remove the quotation marks from there.
If you cannot efficiently control the CSV data you can use __strReplace() function in order to remove the quotation marks from the variables originating from the CSV Data Set Config on the fly like:
${__strReplace(${Username},\",,)}
Demo:
You can install __strReplace() function as well as other Custom JMeter Functions using JMeter Plugins Manager
I had the same issue when I opened a csv file as a normal text file, I saw a Values, value2.
After removing it, it started working as expected.
At the moment, my JMeter test uses a CSV Data Set Config to iterate through a limited set of input data for each HTTP request that I do.
But I don't want to deal with the hassle of an external file (uploading it to my test runner, etc.) - I'd like to just embed the data into the jmx file itself.
I was hoping for something like a "test data" node, that would work similarly to a CSV data set (with Recycle on EOF especially) and I'd just copy/paste the data into the test plan instead of working with an external file.
I'm thinking I might be able to work around it with a JSR223 preprocessor - but is there a better built-in way?
Edit: As per comment: the data cannot be generated.
If you want to do this via JSR223 Test Elements and Groovy language correct syntax would be
vars.put("messageId", "wibble");
vars is a shorthand for JMeterVariables class instance, see the JavaDoc for available functions and properties.
Easier way would be going for User Defined Variables or User Parameters or even better Set Variables Action
You can create a text contains keys and values separated with tab, copy all text
Notice if you have property file you can replace = with tab
Add to JMeter GUI User Defined Variables and click Add from Clipboard
It'll load all your variables to JMeter without "do that by hand using JMeter's GUI"
.
This is my first go at a script based approach using a JSR223 preprocessor node:
// This is where the data is embedded. Up to a couple of hundred entries
// is probably fine, more than that will likely be a bad idea.
def messageIdList = ["graffle", "wibble", "wobble", "flobble", "gibble", ...]
def messageIndex = (vars.getIteration() -1) % (messageIdList.size() -1)
println "iteration ${vars.iteration}, size ${messageIdList.size()}, index: ${messageIndex}"
vars.put("messageId", messageIdList[messageIndex]);
messageIndex++
This appears to do what I want, even when run in a Thread Group with multiple threads.
I'm not sure exactly what the vars.getIteration() represents, and I'm not clear about the precise lifetime / scope of the variables. But it'll do for now.
Any better answers will cheerfully accepted, marked and upvoted.
I'm new to jmeter.
I understand that I can edit jmeter.properties and specify the names of "custom" variables that jmeter will save into its output files, for any given test run.
I've edited jmeter.properties to include this line:
sample_variables=DURATION
and I've also edited my test plan to include a Regular Expression Extractor that extracts a value from each response and stuffs it into a variable of that name.
I also added a "Simple Data Writer" to tell jmeter to write the data it collects to a file.
The output file gets created successfully, but it does not contain the variable I extracted.
What am I doing wrong?
I'm finding this impossible to google, because "save jmeter variable" doesn't constrain the situation nearly enough.
My bad.
Jmeter was writing that variable out.
I had to restart jmeter to get it to work.
I was misled by looking at the top of the output file - it contained output from a prior run, prior to my restart of the tool. After I Removed the existing output file, the new content in the output file showed the variable I expected.
