Is there any report /Graph available in JMETER where I could see Number of user at a time Vs the response time of application under test. This will help me identify what is the performance of application at particular load
It is available in JMeter plugins.
Check this link.
http://jmeter-plugins.org/wiki/ResponseTimesVsThreads/
It has very clear instruction.
Download the latest jar files from the above link
Place them under %JMETER_HOME%/lib/ext folder
You will see new listeners (after restarting JMeter)

I am new to Jmeter , actually I was trying to check the loading time taken for each page in my php application. I used highcharts API for the graphs. When clicking on data menu it will list out all the six graphs. I used Blazemeter chrome extension to record the loading time taken for the six graphs. Once loading time is recorded for each graphs i export the file with .jmx extension which is available in Blazemeter and imported in JMeter and started with iteration for one user, two users , five users and ten users. But when i was checking manually the second graph is taking more time for loading , approximately 7 Secs. But in my JMeter, loading time is shown as 0.534Secs for one user. Please anyone help me how to check the loading time for graphs.
with regards,

This is most probably due to JavaScript-driven requests in your application, i.e. it uses AJAX technology.
As per JMeter project main page JMeter doesn't execute JavaScript found in the webpage, you need to either find a way to kick off the same requests real browsers do or switch to real browsers for your load testing via JMeter WebDriver Sampler.
I have downloaded Apache JMeter 3.1 version and developed a JMX script file. But all my other members use Apache JMeter 3.0 version. I am unable to open my 3.1 jmx file in 3.0 version.
Can anyone suggest how to open the JMX file of 3.1 version in Apache JMeter 3.0 version?
Thanks in advance
Blind shot: my expectation is that you are suffering from Bug #60252. Since JMeter 3.1 a new metric Sent Bytes has been introduced
New Metrics
A new sent_bytes metric has been introduced which reports the bytes sent to server.
Another metric connect_time has been enabled by default in this version
So now Aggregate Report and Summary Report listeners explicitly rely on this metric. If you have these listeners in test plan - just remove them and you should be able to open the script using JMeter 3.0.
Things to consider:
Recommend colleagues upgrading to JMeter 3.1 as newer JMeter versions should normally contain performance improvements and bug fixes
Don't add any listeners to your Test Plan. Really. Listeners should be used for tests development and debugging and viewing test results after test is finished.
Run your test in command-line non-GUI mode like:
jmeter -n -t /path/to/script.jmx -l /path/to/results.jtl
When test is done - open JMeter GUI, add listener(s) of your choice and using "Browse" button locate results.jtl file - you will see saved and calculated metrics
Check out Greedy Listeners - Memory Leeches of Performance Testing article for more details
Raise an issue in JMeter Issue Tracker recommending listing the aforementioned listeners in the Incompatible Changes section
Going forward add essential jmeter.log file parts to your question for non-telepathic community members
As any good software, JMeter takes a big care (believe us as our team leader is an active member of Dev Team) of backward compatiblity but it cannot consider issues when opening a file saved in version N+1 by software in version N (as with any software I think).
So follow Dmitri advice to make your colleagues upgrade to 3.1 for all the good reasons here:
http://www.ubik-ingenierie.com/blog/jmeter-3-1-is-out-with-new-great-features/
But no need to raise a bug (as he recommends) as it is absolutely not a bug.
While recording a workflow through JMeter proxy, I am not able to click some items(like buttons), which otherwise are available when the website is getting loaded without JMeter proxy.
Now, needless to say, i have to click those buttons to perform certain activities essential as a part of the workflow whose performance I want to measure.
I am quite new to JMeter, so not sure how to proceed with the problem. Is there any Proxy settings i should change?
When I am checking the website source there is no difference between the page getting loaded via proxy and the page without it.
Please let me know if additional info is required. Thanks in advance!!!
Check jmeter.log file (usually lives in JMeter's "bin" folder or folder, you launched JMeter from if it's different) for anything suspicious. Log file should be the first place to look into as JMeter basically writes anything there.
You can increase verbosity if required by adding the next line to user.properties file (again lives in "bin" folder of your JMeter installation)
log_level.jmeter.protocol.http.proxy=DEBUG
Try cleaning your browser history, it's better to delete everything, especially cache.
Try re-installing JMeter certificate. See Installing the JMeter CA certificate for HTTPS recording chapter of the HTTP(S) Test Script Recorder (was: HTTP Proxy Server ) for instructions
If above steps won't help and you're absolutely sure you're doing everything right you can try raising a JMeter issue
Also be aware of JMeter Chrome Extension which is an alternative way of recording a JMeter test which doesn't require proxy server.
I am using jmeter for load and performance testing. I am able to successfully generate summary report by using only one user as load. But, if I want to generate summary report for multiple users (say 100 users), how can I configure jmeter GUI to generate summary report?
Thanks in advance :)
JMeter doesn't care about number of users. The only thing to consider: don't use JMeter GUI to perform load test itself.
The easiest approach to use:
Configure your test as required. JMeter GUI can be used at this stage.
Run your test in non-GUI console mode as follows:
jmeter -n -t /path/to/your/test.jmx -l /path/to/test/results.jtl
After load test open JMeter GUI (even empty test plan)
Add the listener of your choice, i.e. Summary Report
Click "Browse" button and open your /path/to/test/results.jtl
Perform analysis, raise bugs, etc.
Also make sure that you're following other recommendations from JMeter Performance and Tuning Tips guide.
You have to put the Summary Report controller at the top level, just beside (not inside) the Thread Group. Otherways, its scope becomes a single thread, which is not useful.
We had scripted an .exe application in load runner and We would like to try it out with JMeter.
The script is very complex and I'm not sure if JMeter could support it, any possibilities available?
I have been a devoted user of Apache JMeter for the past decade and it does offer helpful web load testing functionality for free. Here are some pointers that may help determine if JMeter is right for you:
Apache JMeter is a Java application, so it does have upper limits on resources (memory, sockets, threads). These resources can often be increased or consumption optimized (standard JVM args or jmeter.properties file) for better performance under heavy load testing.
When capturing scripts using the "HTTP Proxy Server" node, make sure that you have a "User Defined Variables" node created and populated with your name/value pairs for the test. This will trigger a variable substitution in the proxy server. This is invaluable when you want to parameterize the script.
As with tree based structures, position determines scope. Make sure that you isolate actions under the proper node or else they will execute for everything at the same scope.
For simulated delays, I have had a good run with the "Uniform Random Timer" where you can specify a lower and upper limit.
For validation, the "Response Assertion" is helpful for raw strings and regular expressions.
For variable extraction, the "Regular Expression Extractor" allows you to extract a value from a page and reference it in a variable for the rest of the test. Node scope appears to be treated as global for these extractors.
When watching the test, "Aggregate Graph" is helpful. "View Results Tree" is useful when troubleshooting, but adds extra memory usage to tests and can cause heavy tests to fail. Note that if you save the results on a listener node, you can reload those results in the control at a later time. Also, if you highlight the table in "Aggregate Graph" or "Aggregate Report", you can paste the results into Excel directly. Very helpful for reporting.
Hopefully this gives you an idea of some of the value and gotchas with Apache JMeter.
You have built a test script within Load Runner and you want it to simply run in JMeter — that's not gonna happen. These are two different test tools.
Rebuild the script in JMeter and it will run as smoothly as your script with Load Runner.
Now you can execute JMeter script inside Load Runner, check
How-to run JMeter test in LoadRunner:
Starting with Micro Focus LoadRunner (LR) 12.55 and Performance Center (PC) 12.55, you can execute JMeter tests in addition to other LoadRunner scripts.
Setting for LoadRunner scenario with a JMeter test:
Open LR Controller
Select the JMeter Scripts radio button
Press the Browse… button
Select JMeter Test file (e.g. Test_1.jmx) and click Open
Click OK button on the next window
