csv file :path
Actually CSV files are not copied automatically in Slave systems, you need to place the CSV required to Slave systems manually as per the path mentioned in CSV Data Set Config element. Use Absolute path.

I have encounter a challenge where I have to read a CSV file and read it till a defined variable size limit( BATCH_SIZE). Once the no of lines from CSV has been read then send it to different AWS API. As my CSV file size can be anywhere 1Gb to 2Gb, therefore I am avoiding to use JSR223 CSV file read.
I want to know how can I can achieve it with JMeter and CSV Data Set Config.
Theoretically you can achieve it using CSV Data Set Config by putting it under the Loop Controller and using your BATCH_SIZE as the loop count.
Another option is importing your CSV file to the RDBMS and use JMeter's JDBC Request sampler for accessing the data
Another solution could be by placing the CSV Data Set Config under a While Controller.
${__groovy(vars.get("__jm__WC__idx").toInteger()< vars.get("BATCH_SIZE").toInteger())}
We want to use 100 credentials from .csv but I would rather like to know if there is any other alternative to this available in jmeter.
If you have the credentials in the CSV file there are no better ways of "feeding" them to JMeter than CSV Data Set Config.
Just in case if you're still looking for alternatives:
__CSVRead() function. The disadvantage is that the function reads the whole file into memory which might be a problem for large CSV files. The advantage is that you can choose/change the name of the CSV file dynamically (in the runtime) while with the CSV Data Set Config it has to be immutable and cannot be changed once it's initialized.
JDBC Test Elements - allows fetching data (i.e. credentials) from the database rather than from file
Redis Data Set - allows fetching data from Redis data storage
HTTP Simple Table Server - exposes simple HTTP API for fetching data from CSV (useful for distributed architecture when you want to ensure that different JMeter slaves will use the different data), this way you don't have to copy .csv file to slave machines and split it
There are few alternatives
JMeter Plugin for reading random CVS data : Random CSV Data Set Config
JMeter function : __CSVRead
Reading CSV file data from a JSR223 Pre Processor
CSV Data Set Config is simple, easier to user and available out of the box.
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 have CSV DataSet Config where I have location of my .csv file
Tried both by writing the absolute path and putting my file in the same directory. Below is the screenshot
CSV file gets stored but the next line says it must exist
Below is mine HTTP Request
HTTP REquest
By running this in command Line nothing is getting stored in the my output file
I have tried that too.
Check following things:
Name of the file is correct. In case of Unix file names are case sensitive so check the name of the file and name you have mentioned in CSV data set configuration.
Keep the CSV file in the same folder where your JMX resides, and just mention file name in CSV dataset config. This avoids confusion in future even if you move the script to any other box.
Also make sure in the file there is no new line character at the end of the file. That will result in error.
Try a fully qualified path. ~/... was not working for me either - /temp/file.csv did the trick
In my JMeter test, I have a Loop Controller nested inside a few other modules with contains a CSV Data Set Config. I also have a CSV Data Set Config in the top of my Thread Group that reads from a CSV to get a file location. I was to use this file location in the nested CSV Data Set Confing to grab the CSV from that location and loop through that one. An error is being thrown because all the CSV files are loaded at once, in the beginning of the test. Is there a way to delay the loading of a CSV so that I can ensure the file path variable has already been set?
You will not be able to use CSV Data Set Config the way you describe. All the config elements get loaded before the test begins.
You can use Beanshell Pre/Post Processor/Sampler.
I had a requirement to load csv file in CSV Data set config of my JMeter script- Name of the csv file can be anything. I run my script with ANT. So i get the name from ANT and pass it to JMeter via a property. CSV data set config uses the property to load the CSV. Thought of sharing this as It might help you as I am not sure of your exact requirement.
EDIT:
You can have a look # __CSVRead(), __StringFromFile() functions.
