I have a JMeter script which tests a couple of requests against my local server running on localhost:9002. I let the tests run for 5 minutes.
As I want to do some automation I need the JMeter script to wait until my local server startup has completed (which will be around 10 minutes)
Is it possible to let my JMeter script wait until localhost:9002 is available and then start to fire the requests for 5 minutes?
Add setUp Thread Group to your Test Plan
Add While Controller to the setUp Thread Group and use the following __groovy() function as the condition:
${__groovy(!vars.get('continue').equals('false'),)}
Add HTTP Request sampler to your Test Plan and configure it like:
Add JSR223 PostProcessor as a child of the HTTP Request sampler and put the following code into "Script" area:
if (prev.isSuccessful()) {
vars.put('continue', 'false')
}
That's it, While Controller will loop the HTTP Request sampler until it will be successful which means that your application is up and running.

I am trying to execute my JMeter script via Azure Load Testing, I have setup a duration time in the JMeter script but when I execute via Azure Load Testing ,it does not get reflected, I cant figure from where the time is getting set. I am not sure how to configure that or where it gets overridden. Any support is appreciated.
If you provided duration_in_sec in your Azure Load Test Configuration - it will override whatever you have in the .jmx test script
If you didn't - the duration will be taken from the Thread Group(s)
If you haven't specified duration in the Thread Group - the test will end as soon as the last thread (virtual user) executes last iteration of the last Sampler in the last Thread Group.
Otherwise you test will run forever.

I'm running tests with JMeter (master+10 slaves) on elasticasearch. I'm getting error 400 for some requests but they are a bit elusive:
When I run the requests manually with curl or pasting them on kibana's console, I don't get errors.
Every time I run the tests using jmeter, using the same requests and under the same conditions, I get a different number of errors.
So I was thinking of inspecting the response bodies from jmeter. But all the ways I've tried failed:
I've created a View Result Tree element and checked all boxes on the "configure" panel. When I run the script, it logs everything except response data
I've tried a BeanShell post processor to write all responses on a file. But it apparently is being 'ignored' when I run the script
Both these solutions work on my machine, but not on the server (which I don't have total control over). I'm passing jmeter.save.saveservice.response_data=true on the command line to start jmeter.
What else could I try?
This is an optimization that JMeter makes for distributed testing related to the mode:
https://jmeter.apache.org/usermanual/properties_reference.html#remote_batching_config
To avoid JMeter stripping the response data set in user.properties of servers snd controller:
mode=Batch
As by default it is:
mode=StrippedBatch
By default JMeter slaves don't send response data to the master, you can choose a different sample sender if you need more data.
Writing response data into a file using Beanshell should work in any case (however consider using JSR223 Test Elements and Groovy for this), just make sure that:
your Beanshell PostProcessor is placed correctly according to JMeter Scoping Rules
there are no Beanshell-related messages in jmeter.log files
you will need to collect the log files from each slave manually after test run, they will not be generated on the master
I am new using the Apache JMeter, I am currently using JMeter for stress test to load balancer. There are 2 Web Server pointing to the single database server. All the configuration load balancer was successfully configure and work fine. After using the JMeter, i able to create a different scenario, i.e shutdown one of the web server or removing the index file. JMeter also working fine display all the request and result each request either the thread (user) getting 404 or 200. Any idea on how to create and configure so that JMeter will display and count each the result, i.e How many number getting HTTP-response code 404 or 200 ? It possible to generate the result and transform it into the graph using the JMeter ?
Configuration:
Server
-Thread Group (50 Sample)
-HTTP Request
-Regular Expression Extractor (disabled)
-Response Assertion (disabled)
-View Result Tree
-Debug Sampler (disabled)
-Graph Results
-Summary Report
You do have the results already
Remove all the listeners from your Test Plan, the listeners don't add any value and just consume valuable resources
Run your JMeter test in command-line non-GUI mode like
jmeter -n -t test.jmx -l result.csv
Open the result.csv file with MS Excel or LibreOffice Calc or equivalent - you will have timeStamp and responseCode columns which will allow you to build some form of "Response code over time" chart
Another option is using Response Codes per Second chart:
It is not a part of JMeter distribution bundle, it can be installed using JMeter Plugins Manager
And finally you can store the status code of the response into a JMeter Variable using Regular Expression Extractor configured like:
once done you can add the next line to user.properties file:
sample_variables=statusCode
and plot this custom variable to the HTML Reporting Dashboard
You can generate JMeter dasboard which include Errors summary:
You can create dashboard using existing log file:
jmeter -g <log file> -o <Path to output folder>
I am running a jmeter test, POST submitting a request i need to check the application log(openshift) to find an application specific message/id is generated ,it need to be captured as its a test data for my subsequent request. Any solution is much appreciated.
Depending on your setup you can go for:
Normal HTTP Request call to /api/v1/namespaces/$NAMESPACE/pods/$NAME/log
Run oc log command using OS Process Sampler or SSH Command sampler
Hello every one my question is that can jmeter record the scripts while we are running our test plan. Like i need to get the http requests from server during execution of my test and instantly update my test plan. If yes please let me know how?
Run JMeter test plan.
Capture the HTTP requests using Fiddler Export
Fiddler session as JMeter test plan. Refer this link
You can record JMeter test execution.
To do so:
Launch JMeter instance #1
Choose File -> Templates -> Recording -> Create from the top menu
Under Workbench choose HTTP(S) Test Script Recorder and click Start
Launch your main test by running JMeter instance # 2 in command-line non-GUI mode through JMeter instance #1 proxy as:
jmeter -H localhost -P 8888 -n -t /path/to/your/testplan.jmx -l /path/to/results.jtl
There is no easy and obvious way to change the plan which is being executed on the fly. If you need to change specific bits consider converting some hard-coded values into dynamic JMeter Variables and perform:
parametrisation - via i.e. CSV Data Set Config
or correlation via i.e. Regular Expression Extractor
