How to open Jmeter jtl file in Excel example

jMeter – Listeners

jMeter – Listeners

Advertisements

Listeners provide access to the information JMeter gathers about the test cases while JMeter runs. The results or information gathered by listeners can be shown in the form of −

tree

tables

graphs

log file

All listeners write the same raw data to the output file when one is specified.

Default Configuration

The default items to be saved can be defined in one of the following two ways −

In the jmeter.properties (or user.properties) file. This file is present in the /bin folder of JMeter.To change the default format, find the following line in jmeter.properties −

jmeter.save.saveservice.output_format=

By using the Config popup as shown in the following screenshot −

JMeter creates results of a test run as JMeter Text Logs(JTL). These are normally called JTL files, as that is the default extension − but any extension can be used.

If multiple tests are run using the same output file name, then JMeter automatically appends new data at the end of the file.

The listener can record results to a file but not to the UI. It is meant to provide an efficient means of recording data by eliminating GUI overhead.

When running in −

GUI mode − use the listener Simple Data Writer

non-GUI mode − the -l flag can be used to create a data file.

Listeners can use a lot of memory if there are a lot of samples. To minimize the amount of memory needed, use the Simple Data Write with CSV format.

CSV Log format

The CSV log format depends on which data items are selected in the configuration. Only the specified data items are recorded in the file. The order of appearance of columns is fixed, and is as follows −

Field Description Value Example timeStamp in milliseconds since 1/1/1970 1354223881017 elapsed in milliseconds 1858 label sampler label HTTP Request responseCode e.g. 200, 404 200 responseMessage e.g. OK OK threadName Thread Group 1-1 dataType e.g. text text success true or false true failureMessage if any bytes number of bytes in the sample 34908 grpThreads number of active threads in this thread group 1 allThreads total number of active threads in all groups 1 URL http://tutorialspoint.com Filename if Save Response to File was used latency time to first response 132 encoding utf-8 SampleCount number of samples (1, unless multiple samples are aggregated) 1 ErrorCount number of errors (0 or 1, unless multiple samples are aggregated) 0 Hostname where the sample was generated LaptopManisha IdleTime number of milliseconds of ‘Idle’ time (normally 0) Variables if specified

Saving Response Data

The response data can be saved in the XML log file if required. However it does not allow to save large files and images. In such cases, use the Post-Processor Save_Responses_to_a_file. This generates a new file for each sample, and saves the file name with the sample. The file name can then be included in the sample log output. The data will be retrieved from the file if necessary when the sample log file is reloaded.

Loading (reading) response data

To view an existing results file, you can use the file “Browse…” button to select a file. If necessary, just create a dummy testplan with the appropriate Listener in it.

Saving the Listener GUI Data

JMeter is capable of saving any listener as a PNG file. To do so,

Select the listener in the left panel by selecting Edit → Save As Image. A file dialog appears.

Enter the desired name.

Save the listener.

How to read the jtl file

Resolution

To view the jtl file perform the following steps.1. Open JMeter and load the script in question.2. In the ASM UI, go to the logs of the Script Monitor that is showing an error. On the side menu, click on Analysis -> Logs and select the monitor.3. Click on the Root Cause Analysis (or Detailed Analysis) icon in the log.

4. Once the analysis window opens up, scroll down and look for the link to the jtl file as you see it below.

5. Once you download it, go back to your JMeter and ensure your script has a View Results Tree in it. If not, right click on Thread Group -> Add -> Listener -> View Results Tree

6. Select View Results Tree and in the screenshot below, click on Browse and open the jtl file you have downloaded.

7. Once loaded, you can then view your steps in the Text view and on the Sampler Result will be the result of the steps. Green means the step passed. Red means the step failed. The Sampler Result will have an explanation as to how it failed.

How to Save Response Data in JMeter

Table of Contents:

Performance test developers often encounter situations when it is necessary to save response data from a server to a file. This may be needed for various reasons. Let’s consider some of them:

Debugging failed requests – This is the most common reason. We don’t have the ability to see responses in the JMeter interface in real time when running a performance test in Non-GUI mode. So, checking responses after a performance test can be helpful for understanding the reason for requests failures.

Saving responses is the purpose of the test – Sometimes saving the response data is the purpose of the test. We can use this data for subsequent analysis, importing to a database and more.

– Sometimes saving the response data is the purpose of the test. We can use this data for subsequent analysis, importing to a database and more. Sharing response data – Sharing response results with teammates could be useful for various reasons. We may want to show artifacts in the responses from the server or ask for help with debugging.

– Sharing response results with teammates could be useful for various reasons. We may want to show artifacts in the responses from the server or ask for help with debugging. The response is too large – We will not be able to see a response in the View Results Tree if the size of the response is more than 200K. There are a couple of ways to solve this problem and one of them is saving the response to a file.

Of course, there could be additional reasons to saving responses from the server to a file. It all depends on your project needs. Let’s discuss how to do it with Apache JMeter™ in this blog post.

We will need a simple JMeter script to demonstrate the various approaches to saving responses from the server. I chose the BlazeDemo website (http://blazedemo.com/) to create our performance script and run the tests.

What are we waiting for? Let’s get started!

1. Add a Thread Group to the Test plan.

Test plan -> Add -> Thread (Users) -> Thread Group

2. Add a HTTP Request which opens the landing page of the test web app.

Thread Group -> Add -> Sampler -> HTTP Request

Set the following values:

Name: HTTP Request – Passed

Server name or IP: blazedemo.com

3. Add a Response Assertion to the HTTP Request – Passed. This assertion will check if the page is correct.

HTTP Request – Passed -> Add -> Assertions -> Response Assertion

Add a row to Patterns to the Test field:

This assertion is correct and the sample should pass every time since the text is presented on the page.

4. Add another HTTP Request.

Thread Group -> Add -> Sampler -> HTTP Request

Set the values:

Name: HTTP Request – Failed

Server name or IP: blazedemo.com

5. Add a Response Assertion to the HTTP Request – Failed. This assertion will also check if the page loaded correctly. But let’s fill the ‘Pattern to Test’ field with an incorrect verification value. We will use it for demo purposes.

HTTP Request – Failed -> Add -> Assertions -> Response Assertion

Add a row to the Patterns to Test field:

Welcome to the Simple Travel Agency! Fail

This assertion is incorrect and the sample should fail each time because the text isn’t presented on the page.

6. We are just about done! Add a listener to see the test results.

Thread Group -> Add -> Listener -> View Results Tree

7. Run the script.

As we can see, each request has a response in the View Results Tree. This is very comfortable for debugging. We can see the actual page and understand what is wrong. Now let’s see how we can save these results to a file.

The first option for saving response data is listeners that have ‘Write results to a file / Read from file’ sections. Examples of such listeners are the View Results Tree, the Simple Data Writer and the View Results in Table. There are more.

We will use a View Results Tree listener for this demonstration.

8. Update the ‘Write results to a file / Read from file’ section in the View Results Tree listener.

Set a filename to save the results to:

Filename: test_results.csv

IMPORTANT. You may need to set an absolute location in the Filename field.

9. Run the script and upload the results to JMeter.

Run the script by pressing the run button. Script results will be saved to the test_results.csv file on the computer. Clean results and upload the file: test_results.csv, by using the Browse button in the ‘Write results to a file / Read from file’ section.

As we can see, the View Results Tree is showing all the requests that took place during the test run. We can see if a request passed or failed, but we can’t see the actual responses, and respectively we can’t understand the failure reason.

10. Let’s play with the listener configuration to store the responses to files.

Change the name of the file to test_result.xml.

Click the Configure button.

Check the Save As XML and Save Response Data (XML) checkboxes.

Save those changes by clicking Done.

11. Run the script, clean the results and upload the results from the file again.

Now we can see not only a list of requests with their statuses in the View Results Tree, but also responses from the server. Isn’t that cool! Now we can easily understand why a request failed.

This approach has one significant downfall. In a real load testing scenario, storing all of these requests could be too much for your workstation. Let’s fix this problem.

12. Let’s save the request/response only for failed requests.

Check the Errors checkbox on the View Results Tree listener.

Run, clean and upload results again.

Now the request list contains only a list of failed requests with saved response data. This is a better approach when we are running real performance tests.

There is another useful listener called the ‘Save Responses to a File’ listener. This listener is is implemented especially for saving responses from a server to files. It generates a new file for each sample, and saves the file with the response data.

Let’s see how it works.

13. Add a Save Responses to a file listener to the HTTP Request – Failed.

HTTP Request – Failed -> Add -> Listeners -> Save Responses to a file

Fill the Filename prefix field with blazedemo.

IMPORTANT. You may need to set an absolute location for the Filename prefix field.

14. Run the script. And open the folder where results should be saved.

We should see the ‘blazedemo1.html’ file in this folder. Open it with a browser.

The browser will open an HTML version of response. This is a very visual approach to storing response data to a file.

Let’s consider one more approach to storing response data to a file. This approach uses JMeter properties. It is a better fit for a Non-GUI mode of running performance tests.

Just to make it clear: previous approaches also work in Non-GUI mode.

The Jmeter.properties file is located in the bin folder of JMeter. Open it with your prefered editor. There are plenty of useful properties there, but we are interested only in a couple of them.

#jmeter.save.saveservice.output_format=csv

#jmeter.save.saveservice.response_data=false

#jmeter.save.saveservice.response_data.on_error=false

By default, JMeter saves the test results in csv format without storing the response data.

15. Let’s set JMeter properties to store the response data to a file and run the script.

Set the properties with the following values and save the file.

jmeter.save.saveservice.output_format=xml

jmeter.save.saveservice.response_data=true

#jmeter.save.saveservice.response_data.on_error=false

Run the script with the option -l. This option determines the location and name of the log file.

jmeter -n -t test_script.jmx -l test_result.jtl

Upload this .jtl file with the View Results Tree listener Browse button. You can also view the results in a text editor, but the listener is more convenient.

The log contains a list of requests with their statuses, just like the responses from the server. This is better, but still not perfect, since storing responses for all requests could take a lot of disk space, as we discussed.

16. Let’s change the JMeter setting and run the script again.

Update the jmeter.properties file with the following values.

jmeter.save.saveservice.output_format=xml

#jmeter.save.saveservice.response_data=false

jmeter.save.saveservice.response_data.on_error=true

Run the script, clean the listener and upload the results again.

That’s it. The passed requests have no response data, and the failed requests do. That was our goal!

I hope this blog post was useful for you. I will be glad to answer any questions you might have in the comments section.
