I am having issues with successfully making a GET http request with query parameters reading from a .csv file. I am working with a JSON application. Thank you bunches in advance!

CSV Data Set Config
HTTP GET Request
I don't see any "issues" with your configuration
Given you have test.csv file which looks like this:
1,2,3
4,5,6
7,8,9
your setup should read the next line on next iteration and populate request details with the values from the CSV file:
If this is not the case for you:
Check the path to the CSV file, it must exist and be readable otherwise your request won't be executed
Check jmeter.log file for any suspicious entries
Check generated JMeter Variables using Debug Sampler and View Results Tree listener combination

Issue : When i tried to send a part of Json body from the csv file in the request getting ERR . I know as per the reference document it throws ERR when uable to open the csv file Or spaces.
Not sure what went wrong.
Below are the screenshots
Check what's in jmeter.log file
Normally you cannot use JMeter Variables as the CSV file path in the CSV Data Set Config, as per JMeter Test Elements Execution Order the CSV Data Set Config is being executed before anything else so the variable might not be yet initialized.
If this is the case - consider using __CSVRead() function instead, check out How to Pick Different CSV Files at JMeter Runtime article for more details.
If this is not the case - check both variables values using Debug Sampler and the presence of the file under the path where ${dealmemodetails} variable is pointing.
I am trying to save Jmeter response in CSV file. I have tried some of the answers from StackOver Flow but those are not working.
Can anyone suggest me how can I achieve this?
Note: I have tried this and this.
Most probably it is something not feasible when it comes to CSV files as response data can have delimiter characters which will break your CSV file structure. For example if you use comma as delimiter and your response data contains commas - it will be not possible to save the response into a single CSV "cell".
If you need to save the response data I would recommend using XML format of the .jtl results file for this. You can amend JMeter's default result file configuration as follows:
Add next lines to user.properties file:
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
That's it, next time you run JMeter in command-line non-GUI mode as:
jmeter -n -t test.jmx -l result.xml
the result.xml file will contain the response data which can be examined using either View Results Tree listener or XML viewer/editor of your choice.

If the response of your request can be stored in csv then you can use one of the following
'Save Responses to a file' in Listeners.
Capture the response using regular expression extractor and write the value to a file in Beanshell code.
I have a directory with CSV files. each file contains a list of GET requests I'd like to make with JMeter. What I'd like to do is read all the files in a directory, and then loop through each CSV to send the requests in JMeter. The number of files isn't consistent so I don't want to hard code the file names into CSV samplers.
So in effect I'd like to read all the files in the directory and store the files in an array variable. The loop through the array and send the CSV file to the CSV sampler which will in turn read the CSV file and pass the content to an HTTP Request sampler to send the GET requests.
I created a beanshell script to read the files in the directory and store them in an array, but when I try to pass this to the CSV config element, I get errors stating the variable doesn't exist.
I've tried another beanshell script to read the file and pass the lines to an HTTP request Sampler as a variable, but the issue was, it would store all the file contents in memory per thread.
I'd like to know the best approach to read the files, send the requests and use the response data to generate reports
You will not be able to populate CSV Data Set config using Beanshell as CSV Data Set Config is a Configuration Element and according to Execution Order user manual chapter Configuration Elements are executed before anything else.
Since JMeter 3.1 you should not be using Beanshell, it is recommended to switch to JSR223 Elements and Groovy language
I would recommend going for Directory Listing Config plugin, it scans the provided folder (in your case with CSV files) and stores the found paths to files into a JMeter variable
So you can use the Directory Listing Config in combination with __StringFromFile() or __CSVRead() functions and that should be more or less good way of implementing your requirements.
I am executing one Thread Group which have multiple Http Request. And I am capturing the Error result into a CSV file using Simple Data Writer. But unable to add the response data to the same file. Can you guys please let me know how I can add the response data to this CSV file or is there any other way that we can use for this purpose?
Use simple data writer but change the option to produce XML. Remove CSV and select "Save as XML". There is a option to "Save Response Data(XML)" that is what you require as shown below.
Put the result file output format as ".jtl" and open it in the Excel to see the results.
You don't even need to Simple Data Writer for this, it can be done by amending JMeter Results File Configuration:
Add the next lines to user.properties file (lives in "bin" folder of your JMeter installation)
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data.on_error=true
Restart JMeter to pick the properties up
Next time when you run JMeter in command-line non-GUI mode like
jmeter -n -t test.jmx -l result.jtl
response data for failed samplers will be added to the results.jtl file, you will be able to inspect it using either View Results Tree listener or your favorite text/XML viewer/editor.
I'm new to Jmeter so I hope this question is not too off the wall. I am trying to test an HTTP endpoint that accepts a large JSON payload and processes it. I have collected a few hundred JSON blobs in a file and want to use those as my input for testing. The only way that I have come across for loading the data is using the CSV config. I have a single line of the file for each request. I have attempted to use \n as a delimiter and have also tried adding a tab character \t to the end of each line. My requests all show in put of<EOF>.
Is there a way to read a file of JSON objects, line at a time, and pass them to my endpoint as the body in a POST?
You need to provide more information, to wit: example JSON file (first 2 lines), your CSV Data Set Configuration, jmeter.log file, etc. so we could help.
For the time being I can state that:
Given CSV file looking like:
{"foo":"bar"}
{"baz":"qux"}
And pretty much default CSV Data Set Config setup
JMeter normally reads the CSV data
Be aware that there are alternatives to the CSV Data Set Config, for example:
__CSVRead() function. The equivalent syntax would be ${__CSVRead(test.csv,0)}
__StringFromFile() function. The equivalent syntax would be ${__StringFromFile(test.csv,,,)}
