I have read in best practices for jmeter -
Disable all JMeter graphs as they consume a lot of memory. You can view all of the real time
graphs using the JTLs tab in your web interface.
How is it done?
Also How can i generate graphs from JTL file.
I have read that xml format for saving results to file are pretty expensive in terms of resource utilization.
How can graphs be generated from logs with csv format?

JMeter can create text files containing the results of a test run.
These are normally called JTL files, as that is the default extension
- but any extension can be used.
from https://wiki.apache.org/jmeter/JtlFiles
And you can check how to create a plan here:
https://jmeter.apache.org/usermanual/build-web-test-plan.html
Graph Results
https://jmeter.apache.org/usermanual/component_reference.html#Graph_Results
Graph Results MUST NOT BE USED during load test as it consumes a lot
of resources (memory and CPU). Use it only for either functional
testing or during Test Plan debugging and Validation.
Just don't use it.
And here is some information as how to read the files:
How to make JMeter output graphs from log-file?
Just generate you own graph.
You should design your load testing as follows:
Store only those metrics which are absolutely required (you can control what values to save using properties which names start with jmeter.save.saveservice.*
Run JMeter test in non-GUI mode with all listeners disabled
Once test is finished you can do the following:
Open JMeter GUI, add Listener of your choice, i.e. Aggregate Graph and using "Browse" button locate and open resulting .jtl file. JMeter will render the graph
Use Graphs Generator Listener
See 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article for JMeter performance tips and tweaks.
In Jmeter under Tools -> Generate HTML report:
This opens the dialog:
There you can select the .jtl file.
You also have to select the user.properties file (you find one in the bin directory of Jmeter) and pass a path to an output directory, which has to be empty.
Then you can generate the report, which you will find in the output directory.
There you will find an index.html file which includes the report.

I am not able to show the report to the management team in proper format. if you guys have any standared format or global format then please suggest me.
JMeter's .jtl results file is basically a CSV file containing Sampler start time, elapsed time, connect time, whether it was successful or not, and so on, the columns can be chosen via Results File Configuration
So you need to ask your management what form of "report" do they expect and generate tables and charts they're looking for.
Some options you can use fully or partially:
JMeter Listeners which can read the .jtl file, do some calculations/plotting and save the output in form of CSV or PNG files
JMeter Plugins Command Line Tool which does the same but provides possibility of automation and some extra charts on top
Graphs Generator Listener
It's possible to generate HTML Reporting Dashboard out of the .jtl results file
There is BlazeMeter Uploader plugin (can be installed using JMeter Plugins Manager) which uploads your test results to BlazeMeter and you can export a management-friendly report from there
And last but not the least you can use MS Excel or equivalent to produce whatever output you want
I have 3 listeners setup to write to a file SummaryReport, AggregateReport, and ViewResultsInTable. I am on a MacBook os Big Sur 11.5.2 and JMeter 5.4.1. Weirdly enough, I get the ViewResultsInTable data in both the SummaryReport.csv and AggregateReport.csv. While I am writing the Test Plan, it is easy to recover because the UI Reports are correct. However, when I want to move to the real test and run it from the command line, I won't be able to recover.
Is there any way to clear that up?
Saving and reading the test results are generic in all Listeners. Hence you will get identical test results in all the files.
If you didn't click "Configure" button and changed the metrics to store you will get the same files no matter which listener(s) you use, you just ended up with 3 identical files (plus the .jtl file if you're running your test in command-line non-GUI mode)
In case of Summary Report and Aggregate Report listeners all the metrics you're seeing are calculated from the individual Sample Result entries so if you open the .jtl results file after your non-GUI test execution finishes you will see the calculated aggregate metrics.
In general you should be using Listeners only for tests development and, it doesn't make a lot of sense to add Listeners for the test execution, they don't add any value, just consume valuable resources. So disable/remove all the listeners, you should be able to get all you need from the aforementioned .jtl results file.
If you want to see the output of Aggregate Report and/or Summary Report listeners without opening JMeter GUI - you can generate them from the .jtl results file using JMeter Plugins Command Line Tool
We are using Jmeter for non-regression testing. We want a report with all samplers listed, in the order they ran, and with succes or fail. If fail, we want it to list the reason (which asserts failed and why).
This is the behavior we were getting with old Jmeter using a view result tree outputting to a xml file, and then using the XSL Jmeter transform to create a html report.
In the new report framework, I have not been able to find a way to reproduce this. All types of reports seems to do aggregations.
This is something which is available in JMeter out of the box for quite a while.
Given the following test structure and the results in the View Results Tree listener:
Given you run your JMeter test in command-line non-GUI mode like:
jmeter -n -t test.jmx -l result.csv
Once test finishes you can open the result.csv file using LibreOffice Calc or Microsoft Excel or equivalent and you will be able to see all the requests in the order in which they were executed with success status, assertion failure message (if present) and other JMeter metrics
You can control which metrics to store in the .jtl results file by amending properties responsible for the Results file configuration
I have done a test JMeter and am able to get results.csv or result.jtl.
How do I load it into JMeter from the GUI and command line?
What do you mean by "load"? You have the results, now you need to analyze them. It can be done in different ways depending on how you plan to represent results and what metrics do you need to report, for example:
Using Microsoft Excel or equivalent like Libre Office Calc
Using JMeter GUI:
Open JMeter GUI
Add Listener of your choice to the Test Plan (for example Aggregate Report is quite good)
Using "Browse" button locate your results file and load it
JMeter will parse the results file, perform necessary calculations and display the metrics. If you need you can click "Save Table Data" to export the results for later re-use
You can plot some charts reflecting the test metrics using Graphs Generator Listener
You can generate HTML Reporting Dashboard like:
jmeter -g your_result_file.jtl -o /where/you/want/the/dashboard/to/be/generated
You can use a 3rd-party analysis service like JAnalyzer or BM.Sense
You need to add listener to create jtl and result files.
Write in listener filename: results.csv
I have a JMeter test plan which is running two thread groups, with each thread group containing a controller and HTTP cookie manager. The controller is a custom controller, but I don't think this should affect JMeter's output.
Outside the two thread groups, I have an Aggregate Report component. Here is a screenshot of my TestPlan:
If I run the test in GUI mode, as you would expect, the Aggregate Report creates an.... aggregate report. That is, the results are aggregated on my test/sample labels, and I get one row for each test, and a range of attributes, as below:
I also have configured this Aggregate Report component to output to a file, by entering a filename in the "Filename" section, and pressing the "Configure" button and checking the attributes I'd like to be output (I've kept it simple for now with just the label, elapsed time and response code).
When I run my test from non-gui mode, this output file is the only way to view the results. However, the output file is rather useless and it does not aggregate the results, but instead gives me output similar to the usual jtl output, i.e. it doesn't aggregate the results at all. Pretty useless. Here is the top few lines of my output file, you can clearly see they are not aggregated:
778,HRLogin,200
426,HRLogin,200
784,HRLogin,200
...
So, the obvious question, am I doing something wrong here? Why is my aggregate report output not an aggregate report? Surely JMeter has a way for producing aggregate output in non-gui mode, without me adding any plug-in or extensions. For the record I need to script this process at some point, so opening a JTL in gui mode is not acceptable, I need this entire process to occur within non-gui JMeter and scripts.
Thanks!
The values you see in the Aggregate Report GUI are calculated from the raw data which is stored in the .jtl file.
If you need to make the process unattended, depending on metrics you need to obtain here are the options:
Since JMeter 3.0 there is a HTML Reporting Dashboard which contains some tables and charts. You can either generate a dashboard from existing results file or make it a part of your test. See Generating Reports chapter for the relevant commands.
Another way to get basic HTML report is running JMeter via Ant Task or Maven Plugin - in both cases you'll get test output like:
See Five Ways To Launch a JMeter Test without Using the JMeter GUI guide for details on configuring a JMeter test run through Ant and/or Maven. There is a number of pre-defined .xsl stylesheets in "extras" folder, you can take whatever you like and customize if needed.
You can also consider running your JMeter test via Taurus tool, it provides interactive console and web-based reporting and has few more options to export test results.
