Does exists any way to calculate count of requests under SLA in jmeter from UI? For example, count of requests that response time < 400 ms?
I had a similar problem a while ago and wrote a little tool - see https://github.com/sgoeschl/jmeter-sla-report
Simplest solution is to use Simple Data Writer to save Label, Elapsed Time and / or Latency to a CSV file, which will generate raw output like this:
elapsed,label
423,sampler1
452,sampler2
958,sampler1
152,sampler1
And from here you can take it to any other tool (awk, Excel, etc.) to filter results you want.
Another option is to use BeanShell Listener to generate such report on the fly. Something like this:
long responseTime = sampleResult.getEndTime() - sampleResult.getStartTime();
if(responseTime < 400) {
FileOutputStream f = new FileOutputStream("myreport.csv", true);
PrintStream p = new PrintStream(f);
this.interpreter.setOut(p);
print(sampleResult.getSampleLabel() + "," + responseTime);
f.close();
}
This method, though, may not be performant enough if you are planning to run a stress test with many (more than 200-300) users and many operations that "fit" the filter.
JMeter provides OOTB a Web Report that provides tons of informations regarding your load test using standard metrics like APDEX, Percentiles ...
See this:
http://jmeter.apache.org/usermanual/generating-dashboard.html
If you still want this, do the following:
Add as a child of your request add a Duration Assertion:
All response below it will be marked as failing.
And in the report, you'll have the count of successful requests meeting this SLA criterion.

I am doing load testing on generating report and the requirement is like the report should get generated within 10mins.
It includes one HTTP post request for report generation, and then there is a status check call, which keeps on checking the status of the first request. Once the status of first request changes to complete then the report generation is successful.
Basically I want to start the timer at the begining of the first request and stop the timer once the status is complete and need to add assertion if the time is less than 10 mins then test is pass else fail.
I tried multiple approaches like using Transaction controller, and adding all request under it. But this doesn't give sum but the average response time of all the request under it.
Also, I tried beanshell listener, extracting the response time for every request and adding them all...
var responseTime;
props.put("responseTime", sampleResult.getTime());
log.info(" responseTime :::" + props.get("responseTime"));
log.info("time: "+ sampleResult.getTime());
props.put("responseTime", (sampleResult.getTime()+props.get("responseTime")));
log.info("new responseTime :::" + props.get("responseTime"));
However, I am not interested in adding the response time of these requests, instead I need to just know what is the time elapsed from when the report is triggered and till it gives status as complete.
All the jmeter timers are adding delays, I dnt wish to add delay instead I need it as a timer.
Any help is highly appreciated.
Thank you
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting mainly due to performance reasons so I'll provide one of possible solutions in Grovy
Add JSR223 PostProcessor as a child of the HTTP Request which kicks off the report generation and put the following code there:
vars.putObject('start', System.currentTimeMillis())
Add JSR223 Sampler after checking the status and put the following code there:
def now = System.currentTimeMillis()
def start = vars.getObject('start')
def elapsed = now - start
if (elapsed >= 600000) {
SampleResult.setSuccessful(false)
SampleResult.setResponseMessage('Report generation took: ' + (elapsed / 1000 / 60) + ' minutes instead of 10')
}
Example setup:
I have 2 APIs
Create a workflow (http POST request)
Check workflow status (http GET
request)
I want to performance test on how much time does workflow takes to complete.
Tried two ways:
Option 1 Created a java test that triggers workflow create API and then poll status API to check if status turns to CREATED. I check the time taken in this process which gives me performance results.
Option 2 Was using Gatling to do the same
val createWorkflow = http("create").post("").body(ElFileBody("src/main/resources/weather.json")).asJson.check(status.is(200))
.check(jsonPath("$.id").saveAs("id"))
val statusWorkflow = http("status").get("/${id}")
.check(jsonPath("$.status").saveAs("status")).asJson.check(status.is(200))
val scn = scenario("CREATING")
.exec(createWorkflow)
.repeat(20){exec(statusWorkflow)}
Gatling one didn't really work (or I am doing it in some wrong way). Is there a way in Gatling I can merge multiple requests and do something similar to Option 1
Is there some other tool that can help me out to performance test such scenarios?
I think something like below should work when using Gatling's tryMax
.tryMax(100) {
pause(1)
.exec(http("status").get("/${id}")
.check(jsonPath("$.status").saveAs("status")).asJson.check(status.is(200))
)
}
Note: I didn't try this out locally. More information about tryMax:

Can you recommend plugin or report for Jmeter 4.0 which count number of requests with responses lower than < define time (eg, 200ms, 500ms, etc.)
I would like get answer on below question:
How many requests per sec can be sent that response time of 90% responses is lower than 200ms
How many responses is below 200ms from Total
% of responses to the response below 200 ms from Total
I'm not aware of any existing plugin which implements your requirement, however you can achieve this using JSR223 Listener
Add JSR223 Listener to your Test Plan
Put the following Groovy code into "Script" area:
if (prev.getTime() < 200) {
prev.setSampleLabel(prev.getSampleLabel() + " < 200")
}
That's it, if your Sampler response time will be below 200 the JSR223 Listener will amend its label and add < 200 postfix to it.
You can view total number of samplers with response time below 200 ms and 90% percentile using "normal" Aggregate Report listener
You can use "Duration Assertion". It will fail all the requests which take more than the expected time and with the "View Result Tree" or "Simple Data writer" listener you can get all the required data and count from the csv/jtl file generated by them.
Hope this help.
Unless you will need absolute numbers, I would recommend the Response Times Percentiles listener (https://jmeter-plugins.org/wiki/RespTimePercentiles/)
This listener will paint a graph of response times and this will clearly show in percentiles below any response time within the range
I am new to Jmeter and working on JDBC. I am interested to know:
How to change field/header names while exporting data to csv file.
How to display elapsed time in seconds instead of milliseconds.
I would really appreciate, if you please define each step. Being a newbie, it would be easier for me to follow.
The field names are defined in the CSVSaveService.java file, you will need to get JMeter sources, amend field names as required and rebuild JMeter. See How to write a plugin for JMeter article for more information
There you can change it in the same file like:
elapsed = Long.parseLong(text) / 1000 // convert ms to seconds
However I wouldn't recommend going for these approaches as there could be side effects in reporting systems.
Instead of patching JMeter you can add a JSR223 Listener and write your own CSV file using Groovy code
For example this is how you can write elapsed time in seconds into a new file called results.csv
def myFile = new File('results.csv')
myFile.append(sampleResult.getTime() / 1000)
myFile.append(System.getProperty('line.separator'))
I want to limit server calls to 400. For that I need to check if I pass 400+ queries will it give me error.
And how write code for 1 user repeated 400 times over a minute.
val UIScenario = scenario("UI Simulation")
.repeat(400)
{
exec(loginScns).exec(search)
}
setUp(
delphiUIScenario.inject(rampUsers(1) over(1 second))
).protocols(httpProtocol)
Please help to sort out this
Thanks !!!!!!!!!!!!
For such as scenarios you can use Apache Benchmark tool. Here is homepage and documentation of it.
