I am using Jmeter 3.3 for executing performance script. Currently Java got upgraded in server from 1.7 to 1.8. Now while executing script on submitting SSO stub page for doing SSL handshake where there is redirection from one end point URL to another exists, its taking more than 60secs to redirect, whereas manually it hardly takes15-20 secs. Same script took hardly 10secs before java upgrade. Any idea how to resolve this Jmeter issue
This might be due to JEP-115 which adds GCM algorithm which is on one hand secure and on another is quite slow or other security enhancements
If it impacts your tests you can disable the algorithm by taking the next steps:
Create java.security file in "bin" folder of your JMeter installation
Add the next line to it:
jdk.tls.disabledAlgorithms=SSLv3,GCM
Then add the next line to system.properties file (lives in "bin" folder of your JMeter installation)
java.security.properties=java.security
Also consider upgrading to JMeter 4.0 as you should be always using the latest JMeter version according to JMeter Best Practices

I am trying to execute a .jmx script in the GitHub. The login page requires a OTP, which I am generating using org.jboss.aerogear. However, it seems when I am executing the script in GitHub the script is not generating this OTP and throwing 406 (Not Acceptable). Can anyone please guide me on this issue please.
This is running perfectly in JMeter but getting error in GitHub.
Do I need to add this specific driver and how?
Whenever you face any "error" first of all take a look at jmeter.log file, normally it contains the reason or at least a clue so you can figure out or guess the error cause. If it doesn't - increase JMeter logging verbosity for the test elements you're using.
Most probably you need to add the .jar file which provides this Totp class (along with dependencies, if any) to JMeter Classpath to JMeter installation in "Github" (whatever it means) and the error will go away
While running the script in non-gui mode for jmeter tests, test gets completed but it does shows min: 0, max: 0...
note:
JMeter 5.4 is installed without any 3rd party plugin.
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)
Please help
It means that none of Samplers were executed and the reasons could be in:
The number of threads in Thread Group is 0
The test contains CSV Data Set Config and the .csv file is not there
The test relies on a JMeter Plugin which is not installed
etc.
The reason should be in jmeter.log file, check it and I believe you will find either the cause or at least a clue there.
Also be aware that according to 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article you should always be using the latest version of JMeter so consider upgrading to JMeter 5.4.1 (or whatever is the latest stable version available at JMeter Downloads page) on next available opportunity
I guess you probably found the answer - but maybe this response will be useful to someone.
I've been battling a similar issue -> locally all was working fine (in GUI and non-GUI mode), but as soon as I tried to run the jmx on the server I could see it would start threads, all logs seemed normal (standard info logs within jmeter.log at start) but still no requests were actually made (confirmed by observing logs from the target server). I tried running trace logs but still nothing out of the ordinary - I could see proper HTTP config, threads were as if normal... But the generated jtl file only contained a header and no requests actually were made.
After some hair pulling I finally found my issue - I'm using variables for threads, rampup and loop which I invoke using ${__P(threads,)} syntax and when running the non-GUI load test I pass those with -J to the command line (f.ex. jmeter -Jthreads=50 ...)
I didn't pass the loop parameter since I figured it would just default to 1 (and that is also the impression I get when looking at the logs where I see all thread started ... entries) - turns out for some reason it will log, but won't execute anything actually till I pass a value for that loop.
So if you run a test plan and notice it only simulates doing something but you get no results in the target log file -> confirm you're setting ALL variables used for thread groups including those you suspect to default
During Distributed testing with Jmeter 3.3 in non gui mode i'm getting error as, how can I fix this :
I'm using same version of JMeter and JDK on Master as well as Slave machines.

I strongly recommend using this jmeter property:
jmeterengine.force.system.exit=true
documented here. These Chinese language web pages link link tipped me off.
You can add -Jjmeterengine.force.system.exit=true on the command line when launching JMeter, or add jmeterengine.force.system.exit=true to JMETER_HOME/bin/jmeter.properties.
How I Confirmed This Fix
With JMeter 5.1 and java version "1.8.0_231" on MS-Win10, we're using a customized version of this JMeter InfluxDB backend Listener.
After my 60 second test run from the command line (jmeter.bat -n -t plan.jtl), the command line hung after displaying this output (very similar to op):
Tidying up ... # Wed Jan 29 14:41:04 CST 2020 (1580330464874)
... end of run
The JVM should have exited but did not.

After modifying my command line as follows, jmeter.bat cleanly exited instead of hanging and all the ugly stack trace went away too:
jmeter.bat -n -Jjmeterengine.force.system.exit=true -t plan.jtl
To confirm that the problem was caused by our customized JMeter InfluxDB backend Listener, I removed it from the .jmx and I also removed the jmeterengine.force.system.exit=true. No hang, no ugly stacktrace (I actually love stacktraces).
I have not taken the next step to discover whether the problem is with the official JMeter InfluxDB backend Listener or with our customized variant, which is not (and will never be) available publicly.
Should mention one gap in this story. I feel this test conclusively points to our customized backend listener (or jmeter's). However, its odd that none of the threads in the above thread dump seem to belong to the backend listener. So I applaud that JMeter did the right thing by dumping the stack trace -- few other apps go to the extent of auto-dumping when appropriate for troubleshooting. But in this case, perhaps that jmeter auto-dump code needs to be enhanced, because it did not point to the culprit backend listener code. Anyone over there at Apache listening in on this?
Good luck.
Most probably your JMeter engine(s) is(are) overloaded therefore cannot gracefully shut down running threads when you request them to do so.
Make sure you follow JMeter Best Practices
The very first "best practice" states Always use latest version of JMeter so consider migrating to JMeter 5.0 or whatever latest version is available at JMeter Downloads page
Make sure your JMeter instances have enough headroom to operate in terms of CPU, RAM and so on. You can use JMeter PerfMon Plugin for this if you don't have other monitoring software in place/in mind.
Take a thread dump and examine it - this way you will know where exactly your test is stuck
Introduce reasonable timeout values in HTTP Request Defaults so in case when server fails to respond JMeter wouldn't wait infinitely but rather fail with an error
And finally (however I wouldn't recommend this) you can suppress this check by adding the next line to user.properties file:
jmeter.exit.check.pause=-1
if you go for this keep in mind that you may run into a situation when JMeter slaves will still be trying to execute something even after your test ends so you will need to kill and restart the processes manually or using a script.
My goal is to run a load test using 4 Azure servers as load generators and 1 Azure server to initiate the test and gather results. I had the distributed test running and I was getting good data. But today when I remote start the test 3 of the 4 load generators fail with all the http transactions erroring. The failed transactions log the following error:
Non HTTP response message: java.lang.ClassNotFoundException: org.apache.commons.logging.impl.Log4jFactory (Caused by java.lang.ClassNotFoundException: org.apache.commons.logging.impl.Log4jFactory)
I confirmed the presence of commons-logging-1.2.jar in the jmeter\lib folder on each machine.
To try to narrow down the issue I set up one Azure server to both initiate the load and run JMeter-server but this fails too. However, if I start the test from the JMeter UI on that same server the test runs OK. I think this rules out a problem in the script or a problem with the Azure machines talking to each other.
I also simplified my test plan down to where it only runs one simple http transaction and this still fails.
I've gone through all the basics: reinstalled jmeter, updated java to the latest version (1.8.0_111), updated the JAVA_HOME environment variable and backed out the most recent Microsoft Security update on the server. Any advice on how to pick this problem apart would be greatly appreciated.
I'm using JMeter 3.0r1743807 and Java 1.8
The Azure servers are running Windows Server 2008 R2
I did get a resolution to this problem. It turned out to be a conflict between some extraneous code in a jar file and a component of JMeter. It was “spooky” because something influenced the load order of referenced jar files and JMeter components.
I had included a jar file in my JMeter script using the “Add directory or jar to classpath” function in the Test Plan. This jar file has a piece of code I needed for my test along with many other components and one of those components, probably a similar logging function, conflicted with a logging function in JMeter. The problem was spooky; the test ran fine for months but started failing at the maximally inconvenient time. The problem was revealed by creating a very simple JMeter test that would load and run just fine. If I opened the simple test in JMeter then, without closing JMeter, opened my problem test, my problem test would not fail. If I reversed the order, opening the problem test followed by the simple test then the simple test would fail too. Given that the problem followed the order in which things loaded I started looking at the jar files and found my suspect.
When I built the script I left the jar file alone thinking that the functions I need might have dependencies to other pieces within the jar. Now that things are broken I need to find out if that is true and happily it is not. So, to fix the problem I changed the extension on my jar file to zip then edited it in 7-zip. I removed all the code except what I needed. I kept all the folders in the path to my needed code, I did this for two reasons; I did not have to update my code that called the functions and when I tried changing the path the functions did not work.
Next I changed the extension on the file back to jar and changed the reference in JMeter’s “Add directory or jar to classpath” function to point to the revised jar. I haven’t seen the failure since.
Many thanks to the folks who looked at this. I hope the resolution will help someone out.
I have a prepared a jmx file using jmeter & ran that test case on blazemeter to test load on my server. After the test is done, I can see that one of my services are failing. Though not all the time, but some times. And in the error tab on blazemeter, i can see that is is giving
Non HTTP response message: The target server failed to respond
I am not sure, that is my server failing to handle the load, or is it something else. In My settings, thread is 50. Can any one please help me that, is this because of server is failing to handle to load. Thanks in advance.
It looks like that you're facing the problem described in Connection Reset since JMeter 2.10 ? Wiki article.
If you upgraded recently to JMeter 2.10 or 2.11, you may have noticed increased errors of this type:
Socket closed
Non HTTP response code: org.apache.http.NoHttpResponseException (the target server failed to respond)
So
Change "Implementation" of your HTTP Requests to HTTPClient4
Add the next 2 lines to user.properties file (usually lives under /bin folder of your JMeter installation)
httpclient4.retrycount=1
hc.parameters.file=hc.parameters
In hc.parameters file (also lives under JMeter's /bin folder) uncomment the following line:
http.connection.stalecheck$Boolean=true
For more information on different JMeter properties and ways of setting and altering them refer to Apache JMeter Properties Customization Guide
Encountered the same issue and fixed it by unchecking the "Use KeepAlive" option for HTTP requests. Please refer to the screenshot. I guess, the root cause was related to the connection being closed and the JMeter client trying to use the same connection.
Had similar problem for jmeter 2.13 DmitriT solution got me pointed in right direction, but in my case the java or HttpClient3.1 worked, 4.0 did not.
I have done everything.
ange "Implementation" of your HTTP Requests to HTTPClient4
Add the next 2 lines to user.properties file (usually lives under /bin folder of your JMeter installation)
httpclient4.retrycount=1
hc.parameters.file=hc.parameters
In hc.parameters file (also lives under JMeter's /bin folder) uncomment the following line:
http.connection.stalecheck$Boolean=true
BUT STILL FACING THIS ISSUE in apache jmeter 5.1
In my case it was the header for the call I was doing that was causing the issue.
It was:
Content-Type:application/json;charset=UTF-8
Set it to:
Content-Type:application/json
