I have 6 scripts to be executed one after the other (Non-GUI mode).
Using Batch Files to achieve the same. Kindly find below the approach taken:
File with Parameters
File with Execution commands
Is there a better approach to implement this?
Thanks for your support.
Regards,
Ajith
I don't know if there is a "better" approach, there are "alternative" approaches i.e.
You can create one "umbrella" .jmx script and reference all your 6 scripts using Include Controllers
You can use Taurus tool as a wrapper for your JMeter tests, example Taurus YAML config file:
execution:
- scenario: test1
- scenario: test2
# etc.
scenarios:
test1:
script: test1.jmx
test2:
script: test2.jmx
#etc
modules:
local:
sequential: true

I want to execute .bash script using OS Process Sampler via Jmeter 5.5
My requirements are:
1 Navigate to the specific path: C:\app\docs\release
2 execute as: ./no_longer_duplicate.bash dwtikz895261 6565
3 dwtikz895261 should be fetched as variable
what I tried is:
What I get is:
Any help is appreciated
If you're trying to run a Bash script you need to provide the bash to Bash interpreter
Something like:
But you seem to have Windows as OS, shouldn't you use Powershell or CMD instead? Or even consider JSR223 Sampler with Groovy, in that case it would be cross-platform
Thanks Dmitri T, but I wasn't able to get my results using OS Process Sampler and bash script on Windows.
The only way that worked for me was using groovy sampler and processBuilder
Here could be found the solution that worked for me -> Jmeter - Execute bash script using 'JSR223 Sampler' and groovy, and output the result
I'm very new to JMeter.
My team has existing JMeter Test Plans that we generally run through the GUI. I am experimenting with running it from the command line.
In our test plans, we have a bunch of variables declared at the TestPlan level. These variables contain information for setting up different environments (eg test, prod, dev). Directly under the TestPlan is a JSR223 PreProcessor that basically takes the variable that shows what environment you're trying to run in and sets up the hostname, port, etc to the values for that environment.
When I run the test using the GUI, it works perfectly under the selected environment. However, when I run it with the command line using the following command:
jmeter -n -t testName.jmx -l Results.csv
it tries to run under the defaulted environment and doesn't change it to the environment I want. I tried adding a -Jenv=dev, but that didn't seem to make any difference.
Do preprocessors not run when called from the command line? Could there be something else that I'm missing? Given my inexperience here, I'm not even really sure how I can tell what the problem is.
Thanks so much!
It is very difficult to conclude what is the exact problem in your jmeter script. Looking into the problem statement I can sense that you need to find correct way of passing a variable from command line and processing it in a script.
Example of passing a variable from command line and handling it in jmeter is shown below:
Declare a variable with value as a property in jmeter. You can use anything here, I have used User Defined variable. Variable env is declared as ${__P(env)}
Using JSR to process that variable. Here just printing the value passed from parameter into jmeter log. Now the value can be reused using ${env} variable [note it is a variable and not a property, because we declared that way in User Defined variable].
String valuePassed = vars.get("env");
log.info("Parameter passed from command line: " + valuePassed);
Run from the Command Line using following command:
jmeter -n -t <>.jmx -Jenv=Prod -j sample.log
Result shown in log file
PreProcessors are executed only in conjunction with Samplers
If you don't have any Sampler in your Thread Group - none of PreProcessors will be executed.
Also be aware that PreProcessors obey JMeter Scoping Rules to wit:
if you have a PreProcessor added as a child of the Sampler - the PreProcessor will be executed before the given Sampler
if you have 2 Samplers and a PreProcessor at the same level - the PreProcessor will be executed before each Sampler
Problem:
I am currently hard coding a password in my jmeter .jmx test file.
I want to be able to either set this in the config.yaml or on the command line using something like a "-o modules.jmeter.properties" switch (to replace this in the CI pipeline)
However I cant get either of these to actually replace the value in the .jmx file.
I have looked through the Taurus doco and ended up trying the following.
Updating the config.yaml file:
execution:
- executor: jmeter
scenario:
script: ../scripts/apigee_loadtesting.jmx
data-sources:
- ../datafiles/
concurrency: 2
ramp-up: 30s
hold-for: 1m
steps: 2
modules:
jmeter:
properties:
es.password: P#ssw0rd!
Also tried this from the commandline:
bzt ../config.yaml -o modules.jmeter.path=/usr/local/apache-jmeter-4.0.2/bin/jmeter \
-o modules.jmeter.properties.espassword=P#ssw0rd! config.yaml
But neither of them seem to do anything meaning, Any suggestions would be appreciated
Taurus itself will not change anything in the .jmx script, just make sure that you refer the property using __P() function as ${__P(es.password,)} in the .jmx script and the value will be substituted with the one from .jmx file or command-line override.
I would avoid using dots in properties names as it might cause problems with overriding properties values from the command-line. So stick to espassword everywhere if possible
The change your command line so config.yaml would be the last argument like:
bzt -o modules.jmeter.path=/usr/local/apache-jmeter-4.0.2/bin/jmeter -o modules.jmeter.properties.espassword=P#ssw0rd! config.yaml

Currently we are using Performance Center for the load test,eventually we will move to JMeter.
In Performance center we ran 200 scripts together.
In the Same way ,How to run multiple jmx scripts together in JMeter?
You can use JMeter Ant Task or JMeter Maven Plugin to kick off tests execution. Both tools have capabilities to execute tasks in parallel.
If needed you can merge execution result files with MergeResults plugin.
For more options on how JMeter test can be started refer to 5 Ways To Launch a JMeter Test without Using the JMeter GUI guide.
Using non-ui mode you can run multiple jmx scripts by providing -t option like,
Jmeter.bat or Jmeter.sh -n -t scritp1.jmx script2.jmx ...
or create multiple sessions using a wrapper script in shell or batch pgming which will run those scripts in parallel
like,
Jmeter.bat or Jmeter.sh -n -t scritp1.jmx &
Jmeter.bat or Jmeter.sh -n -t scritp2.jmx &
The easy way is to start all the scripts from the command line at the same time and have each script programmed with number of users, etc. I use Windows, and create a batch file containing multiple lines like:
start /REALTIME java -jar ApacheJMeter.jar -n -t test_script1.jmx -l results1.jtl -j log1.log -Dthreads=40 -Dduration=1800
However, for the scale of your setup, I would recommend you look into a better method of controlling your testing through automation.
I have set up a Jenkins server, which is able to run JMeter scripts using maven, or shell scripts, and then aggregate results, create graphs, etc. It is able to trigger jobs in parallel, sequence, randomly, or triggered by other events.
I would also look at setting up your scripts to use properties for number of threads, loops and duration, so you can control them easily from Jenkins without modifying the scripts. Create a User Defined Variables config element, and copy property values to variables, setting defaults, ie:
THREADS ${__P("threads", 25)}
This will mean ${THREADS} can be used in the thread group, and will be default value 25. If you assign a value on the command line it will be used instead of default. You can define it on the JVM command line, when you start JMeter like this:
-Dthreads=40
In your script, the value of ${THREADS} will now be 40.
I'm looking for a way to run a jmeter from command line,
collect the data from Summary Report to some file (say every x seconds) during the execution.
Then load the saved file to the jmeter to see the limeline graphs of the collected metrics.
How can I do such thing?
The simplest way automate getting a graph from results is to use a shell script coupled with the 'JMeterPluginsCMD' plugin that allows you to create a graph image from the command line.
Something like:
#!/bin/bash
cd /where/jmeter/is/installed
# Run Test
./jmeter.sh -n -t /path/to/mytest.jmx -l /directory/to/store/results.jtl
# Generate PNG File using plugin
java -jar CMDRunner.jar --tool Reporter --generate-png test.png --input-jtl /directory/to/store/results.jtl --plugin-type ResponseTimesOverTime --width 800 --height 600
To litterally read data from the Summary Report would take a lot more work but I imagine you could do something with awk, however I suspect that this method is not explicitly required and that reading the jtl file (after the test has completed) would work.
Since this is already answered question I'll offer an alternative to .png image and that is .html page. Please take a look at this answer :
