What I try to achieve is to get JMeter results in 2 formats, for the same test execution. CSV is the one I'm mostly interested in, unless there are failures - then I may need to use data which can be saved only to XML. I can't use XML for most occasions, due to misc reasons.
I was looking at jmeter.save.saveservice.output_format cfg entry, it doesn't seem to accept both as valid entry. I was also looking at JMeter code itself, it also clearly separates both options.
Did anyone invent a hack to get both JMeter outputs at the same time?
Solution for both standalone JMeter and jmeter-maven-plugin is welcome.
If you use JMeter Maven plugin, as per Five Ways To Launch a JMeter Test without Using the JMeter GUI guide the default output has to be XML.
If you need CSV output as well - just add Simple Data Writer listener. If you looking for CSV data to be in line with JMeter default CSV values configure it as follows:

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 a JMeter script where I should access a .xls file with multiple tabs and alter values .
The .xls file has values like , RASD1234,TWER1234,ZAST1234 . I should change the numeric value to unique values each iteration like RASD1235,TWER1235,ZAST1235 in all tabs . How can I achieve this in JMeter
Download tika-app.jar and put it into JMeter Classpath
Restart JMeter to pick the .jar up
Once you do this you will be able to use POI-HSSF API to edit the Excel file
Just one piece of advice: since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting so consider doing this in Groovy (normal Java syntax will also work)

How to Implement Data Driven Testing in your JMeter Test
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?
Quote
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.
Is there a way to create a JMeter test plan without going through the GUI?
I.E. can you create a script with pure code?
In a way - yes. You can create the JMX file in a text editor, but it would require knowing what every component needs.
You're better off creating in GUI mode and modifying the JMX file manually as needed.
Yes it's possible to write a test plan just by writing JAVA code.
The key classes to look into are:
StandardJMeterEngine - the main class which configures the Test Plan and executes it
HashTree - a special collection which holds Test Plan elements
A minimum of JMeter Controllers necessary to run the test.
Reference: http://blazemeter.com/blog/5-ways-launch-jmeter-test-without-using-jmeter-gui
I can write and run JMeter without GUI. JMeter use JMX file, as you can here.
Not entirely sure why you would want to write a JMX in this way? ... But yes, entirely possible if you understand the structure of the document.
You could use any basic text editor to achieve this (notepad / notepad++ for example).
A JMX file is a saved JMeter project in XML format. ~ Ref
Depending on your needs you could the browser editor from the JMeter Plugins website.
jmeter-plugins.org/editor/
Or simply save a basic JMX as a template and spend loads of time learning the structure, syntax and namings etc.
I'd like to run a distrubuted JMeter test on our site, following the
manual. My tests are parametrized via a CSV DataSet configuration element to simulate diffent users. The question is now: Will JMeter use the same DataSet for each slave, or can I somehow configure each slave with its own dataset? If the first is the case, slaves will steal each other's session which is of course undesired.
Jmeter use local CSV fiels in distributed mode. So you just place different files on each slave and it works. Nothing special to do.
You can choose the CSV Data behaviour with the Sharing mode option. Description of each option detailed in:
