How to upload unique file. Jmeter distributed testing - jmeter

I have a scenario where I have to upload a unique named text file.I have used counter in the thread level and using the reference name as file name.say If I want to upload the File_1.txt, I have used something like this file_${counter_refname}.This is working like a charm in single machine but, Now the problem is when I run in the distributed mode slave_1 is uploading the File_1.txt and Slave 2 machine is also uploading the same file File_1.txt. The Target server will not allow to upload file with same name. How to resolve this problem??

Use a CSVData Set that will contain file names.
Create 1 file per distributed node referenced by it and ensure all these files never contain the same file name.
To do it, first create 1 file with unique names then split it in as many files as you have nodes.
Another option is to just generate a unique file name if sequence number is not important by using __UUID function:
http://jmeter.apache.org/usermanual/functions.html#__UUID

There is a couple of functions which can help to identify slave machine and parametrize file name.
__machineName() - returns hostname of machine running JMeter instance
__machineIP() - the same for IP address
Also you can look into __Random() or __RandomString() functions to generate unique files with random names on the fly i.e. with Beanshell PreProcessor as follows:
import org.apache.commons.io.FileUtils;
String filename = "file_${__Random(10000,99999,)}.txt";
FileUtils.writeStringToFile(new File(filename), "a quick brown fox", "UTF-8");
vars.put("filename", filename);
Refer to generated file name as ${filename} where required.

How copy and rename copied image in Jmeter

I've been wondering if this is possible on jmeter wherein I copy the original image and rename it via random string and paste it in the same dir.
Yep, take a look at:
OS Process Sampler which allows execution of arbitrary external commands and programs
__RandomString() function which can generate a random string of the specified length from the specified characters
Example setup:

Am I misunderstanding something about using the List and Fetch combination?

I am trying to understand the combination of List and Fetch processors.
I have a directory with three JSON files and I get the ListAzureDataLakeStorage to list them. But when I connect a FetchAzureDataLakeStorage with which I intend to take only one of the files, the Fetch takes the same file three times. In summary, it takes the file whose azure.filename matches with the value that I put in the File Name property, but as many times as there are files in the listed directory.
I really want to use a single List and connect three Fetches to it, each one to take a different file, and thus use them for different streams.
In each Fetch I put in the "File Name" property the name of the file that I want to take. For example:
File Name: fileName1.json
I have also tried putting in "File Name" with Expression Language the following:
FileName: $ {azure.filename: equals ('fileName1.json')}. But this option causes a 404 empty body error.
But there is no way. Am I misunderstanding something about using the List and Fetch combination?
If you are statically entering file names and you want to respond to each one differently, then the ListX processors aren't very beneficial to your flow.
The easier option would be to use a GenerateFlowFile processor with the appropriate schedule to trigger a corresponding FetchX processor.
If you're only doing this for 3 files, it's not too much manual overhead. You could also achieve something similar using RouteOnContent/Attribute.

NiFi: Routing on File Types, e.g. csv, tsv, xlsx

I have a connected SFTP server, and I am trying to route files based on type: .csv, .tsv, and .xlsx. For now, I'm just uploading test files through the command line.
My flow is:
GetSFTP (with correct hostname, etc.) ->
RouteOnAttribute ->
LogAttribute (will dump elsewhere soon, this is just for testing)
My problem, I think, is that I created a property in RouteOnAttribute incorrectly:
Am I correct in assuming that this does not actually pick up on the .csv because it is not technically part of the filename? What would be the correct expression to route on the file type? Thanks!
You need some information that will tell you the type of file.
GetSFTP should be getting the filename from the file on the sftp server, so if those have the appropriate extensions then I would expect your RouteOnAttribute to work correctly.
If the filename does not have the appropriate extension, then the only thing you can do is try to use IdentifyMimeType to determine what type of file it is, and then route on the mime.type attribute.

ibm integration output file name

I am quite new to the world of Integration and IBM Integration Bus Toolkit. I am doing a small exercise with IBM Integration Bus Toolkit, whereby my small application picks up an .txt file in a specified directory and moving it into another one (I am using Message Flow to do it). I can even specify the file name for the output file
What I wanna do now is appending the file name of the output file by adding the current date to it (e.g. output-20180225.txt) but I am not quite sure how and where to do it.
I know there is a function CURRENT_DATEbut I am not so sure how to apply it to the file name.
Using Compute node and writing the following code:
SET OutputLocalEnvironment.WrittenDestination.File.Name = $yourfilename;
you should use local environment tree and in the you modify you file name like this :
Example File name -- Response_20180621035622333.txt
DECLARE currtime CHARACTER CAST(CURRENT_TIMESTAMP AS CHARACTER FORMAT 'yyyyMMddHHmmssSSS');
SET OutputLocalEnvironment.WrittenDestination.File.Name='ResponseFile_'||currtime||'.txt';
this will set the new file name every time with current time stamps.

How to generate csv file in jmeter with unique name for every run time?

I have a doubt.
I want to create "CVS file" with unique name in yy-mm-dd-time format for every run in JMeter.(multiple run) and send report via a mail.
How can i do this?
The Jmeter results can be either generated in .csv or .jtl extensions.
Append the following Jmeter in-built Function to your preferred result file name.
${__time(YMDHMS)}
For Example: TestResult_${__time(YMDHMS)}.csv OR TestResult_${__time(YMDHMS)}.jtl
The result file will be generated as: TestResult_20160224-112120.csv OR TestResult_20160224-112120.jtl
