Execute a file using OS sampler in JMeter on a RHEL 8 Machine - jmeter

Have a .net core library Linux compatible on a Linux machine. I can execute it locally from terminal and getting the expected result. But while executing from JMeter using a OS sampler it is failing.
From Terminal: Running Fine
JMeter Settings:
Fetching the Response Body: (which should be 352 for example from the above terminal)
JMeter it is failing:
Check the file location and permission, everything is in place. What I have missed here any help ?
After change:
I changed as suggested and still facing the issue,
Error details,

I think you need to invoke a shell instead of trying to execute your command directly, something like:
Also if you open the OS Process Sampler in the View Results Tree listener you will see the output or in case of failure the failure reason

I guess you misinterpret both Dimtri and User729 comment, you need to add both places and it should work.

JMeter 5.3 doesn't respond after a click File->Open File on MacOS Monterey 12.5.1

For a few days I cannot open any JMX file in JMeter script. Even after click File->Recently Opened, JMeter opens this file but non of click action on this file doesn't work. I am using JMeter version 5.3.
What I've done:
tried to used another JMeter version (5.5)
unistalled and installed newest JDK version (17.0.4.1)
upgraded all MacOS upgraded
scanned my MACOS in order to find a viruses
opened another applications based on Java and try to open the file (f.e. Intelij)
Increased Heap from 256M to 512M
Killed all denudant processes
Opened the java logs
All these actions were unsuccessful. Slowly my ideas are ran-down. Any idea from you what else can I check?
Best regards.
I cannot reproduce your issue:
so most probably something is wrong with your Java/JMeter/OS/user/whatever.
You can try following troubleshooting steps:
Increase JMeter's logging verbosity to maximum and see whether there are any suspicious entries in jmeter.log file
Check your OS logs using Console application
Try switching to another Look and Feel via Options -> Look and Feel. If this doesn't work as well you can do it using command line i.e.
./jmeter.sh -Jjmeter.laf=CrossPlatform
Try running JMeter and providing the path to the .jmx script via -t command-line argument like:
./jmeter -t /path/to/test.jmx

Server agent not opening in JMeter

I installed serverAgent 2.2.3
When I run it in cmd I get this error.
enter image description here
I tried starting the startAgent. bat. It automatically closes.
Thanks for looking.
That's very weird because the error states that sl4j library cannot be found in CLASSPATH and ServerAgent doesn't use this library at all.
Try downloading it from Github and unpacking it somewhere else. Also if you have CLASSPATH environment variable set - try clearing/unsetting it.
set CLASSPATH= && startAgent.bat

Alternatively you can try downloading sl4j.jar and dropping it near ServerAgent.jar but it is not a part of normal ServerAgent installation procedure.

JMETER_HOME environment variable is not defined correctly but build is successful and the script works fine in Jmeter GUI and cmd prompt

I have created a jmeter jmx script and it is getting executed perfectly in GUI and non GUI mode. I have configured the same in Jenkins but I am getting the build success with an error message as "The JMETER_HOME environment variable is not defined correctly
This environment variable is needed to run this program"
I have also tried setting the JMETER_HOME as E:\apache-jmeter-4.0 in User variables and Path as E:\apache-jmeter-4.0\bin in System Variables and it didn't work.
I tried the below Questions but no luck.
'jmeter' is not recognized as an internal or external command, operable program or batch file
JMETER_HOME environment variable is not defined
Here is my command and error from jenkins
E:\apache-jmeter-4.0\bin\jmeter -jjmeter.save.saveservice.output_format=xml -n -t E:\JMeter Tutorial\JenkinsIntegration.jmx -l E:\JMeter Tutorial\JenkinsIntegrationResult.jtl
The easiest way of setting an environment variable is defining it under Manage Jenkins - Configure System - Global properties:
The better way would be using Environment Injector plugin
And last but not the least, you're getting this message because you're sitting at outdated JMeter 4.0, if you upgrade to i.e. JMeter 5.2.1 you won't be seeing this warning, moreover 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 in any case upgrade does make sense, check out what is the latest stable JMeter version and switch to it
I removed Jenkins and reinstalled as well as i deleted the old job and created a new job with default settings in jenkins (i dint do anything in the manage Jenkins) and it worked charm with both jmerer 4.0 and 5.3. java 1.8.0_251
with 5.3
with 4.0
as far i remember i just removed the space and added underscore in the below command from folder name JMeter Tutorial to Jmeter_Tutorial
E:\apache-jmeter-4.0\bin>E:\apache-jmeter-4.0\bin\jmeter.bat -Jjmeter.save.saveservice.output_format=xml -n -t E:\JMeter_Tutorial\JenkinsIntegration.jmx -l E:\JMeter_Tutorial\JenkinsIntegrationResult.csv

Jenkins job with batch stage has a zombie environment variable

I have a python command line program that can retrieve passwords for me.
I can run it from the command line and get the passwords.
Example command:
passwordmanpro_cli javaprops OpenWeatherMap_DEV
The response comes back fine.
I have the Jenkins agent installed on the machine. I have a "Execute Windows Batch Command" step which calls exactly the same commandline.
This USED to work without an issue. A month ago it stopped working. With an error:
ERROR Success not returned from passwordmanagerpro
Using URL - https://icsecpws.cc.ic.ac.uk:443/restapi/json/v1/resources (AUTHTOKEN ommitted - 36)
ResponseCode - 200
resJSON - {'operation': {'name': 'Authentication', 'result': {'status': 'Failed', 'message': 'User is not allowed to access from this host'}}}
IP Being used to send message might be: 155.198.31.184
Something is different from how this request is sent via a windows terminal and how it is sent from a windows batch step in Jenkins.
I have verified the windows batch command is being run as a correct user.
I have verified the username and password credentials being passed are the same
I have verified the source IP by adding debug lines in python.
The password manager we are using has an API user setup and you enter an IP address the API is allowed to be called from. Apparently the restriction is not done on source IP but a reverse hostname lookup.
Can anyone give me advice on how to debug this further?
Update 1
More debugging has revealed that the cause is the environment is being set wrong. The host machine is windows 10. I have an environment variable called PASSMANCLI_AUTHTOKEN and another called PASSMANCLI_URL
In control panel I am setting both variables system wide. NOT for a particular user.
What is really strange is that the PASSMANCLI_URL is changing and being picked up ok, but the PASSMANCLI_AUTHTOKEN variable is not. I have added a "set" windows batch command in the config and I have confirmed that the PASSMANCLI_AUTHTOKEN value is NOT coming from the system setting but somewhere else. I am wondering if Jenkins does anything special with this.
BTW: I have also used the whoami command as part of the project config and confirmed Jenkins is running as the same user.
Update 2
I have gone through the entire windows registery and looked at all Environment entries and deleted PASSMANCLI_AUTHTOKEN. I have confirmed it is not in the environment console. I have restarted the Jenkins agent and the entire server. I then run my jenkins job with a single command "Set" and it reads back the OLD value of the token!
update 3
I have created a brand new Jenkins job with 1 step which is the windows batch command. It simply has "set" so displays the environment variables. I can see PASSMANCLI_AUTHTOKEN is still being set even though I have completely wiped it from the machine.
update 4
I thought it might be something to do with the way the Jenkins runner uses JAVA. (Our Jenkins runner is using Java 8 32 bit). I wrote a Java program which runs
processBuilder.command("cmd.exe", "/c", "set");
and outputs the result.
I checked the output and the variable is NOT set, as expected.
I still don't know where this variable is coming from when executed via Jenkins.

LINQPad script fails using lprun, works otherwise, need steps to diagnose the issue

Some environment details:
LINQPad v4.47.02(AnyCPU)
OS Name Microsoft Windows Server 2012 Standard
Version 6.2.9200 Build 9200
System Type x64-based PC
I am trying to figure out how I might diagnose an issue I am encountering when launching a script via the lprun.exe command line utility. When I run the script from the IDE interactively it runs and completes without any exceptions.
When the same script is run under the same user from the command line using: lprun.exe
I get this output.
c:\SQLTasks\Linqpad\Demographics\Demo_GenerateDemographicsSubset.linq(880,20) :
error CS0029: Cannot implicitly convert type 'string' to 'char?'
Due to how LINQPad compiles the script I cant easily locate the area in my script that might be causing this and I'd really like to know if possible what mechanisms might allow it to work interactively and fail from the command line.
Please refer to the discussion on the LINQPad forum: http://forum.linqpad.net/discussion/437/lprun-exe-runtime-error-doesn-t-hapen-when-script-is-run-from-linqpad-ide#latest
Edit: this was due to a bug in how LINQPad reads configuration settings in command-line mode. The bug was fixed as of v4.48.
