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 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:
Pardon me if this is already answered (newbie to JMeter).
I have a situation where, I have to read 100,000 URLs from a CSV file but all the URLs should only be run once, along with achieving 500 req/sec load on server. Tried using Once Only Controller with a Thread count of 100, but every thread read only one URL and stops after reading first 100 URLs.
My CSV file looks like this:
URL1
URL2
...
URL100000
I have called my HTTP sampler inside Once Only Controller
Is there something that I am doing wrong here ??
Use the Constant throughput timer(req/min) to have your desired TPS (req/sec)
your TPS will be proportional to the number of active threads.
Ref: https://www.blazemeter.com/blog/how-use-jmeters-throughput-constant-timer.
Do not use Only Once Controller . It will run the thread(100 in your case) only once(each thread hits 1 URL and exits) . Rather use a HTTP Request.
You can do this using Throughput shaping timer.
First in your CSV Config Make sure you set recycle on EOF to false, which means that if JMeter reads all lines it wont start from beginning again.
Add a throughput shaping timer to your http request and mention start RPS as 500 end RPS ass 500 and duration 200 seconds
That means you are telling JMeter to hit 100000 requests in 200 seconds (500 per second * 200 seconds=10000 requets).
To calculate thread pool size use the formula rps*Max response time/1000, Add some extra threads to this value .
For more info on throughput shaping timer please follow this link
I have an MVC Web aPI and I have trouble in comparing the response time of this API. I added some code to calculate the response time:
In the AuthorizationFilterAttribute OnAuthorization, I have the below code:
actionContext.Request.Headers.Add("RequestStartTime", DateTime.Now.ToString());
I have an ActionFilterAttribute, and an OnActionExecuted in which I have the below code:
string strRequestStartTime = actionExecutedContext.Request.Headers.GetValues("RequestStartTime").First();
DateTime dtstartTime = DateTime.Parse(strRequestStartTime);
TimeSpan tsTimeTaken = DateTime.Now.Subtract(dtstartTime);
actionExecutedContext.Response.Headers.Add("RequestProcessingTime", tsTimeTaken.TotalMilliseconds + "ms");
The response has the header "RequestProcessingTime" in milli seconds. The issue is whenever I try the same request using Postman/JMeter, I see that the response time is lesser than what I see in my Response. Why is this happening?
I think this is due to the fact the header does not consider time for request to reach the server and response to travel back, my expectation is that it shows only the time, required to process the request on the server side. So JMeter reports time as delta from the time when request has been sent and the time when the last byte has been received, which is more correct in terms of real user experience.
See definitions of "Elapsed Time", "Connect Time" and "Latency" in the JMeter Glossary. You may also be interested in How to Analyze the Results of a Load Test article which demonstrates the impact of network capacity on the overall performance
How to generte csv file and load csv using response time graph listener?
Can any one help me in detail that how we find response time in jmeter ?
If you run JMeter in command-line non-GUI mode as follows:
jmeter -n -t /path/to/your/test_plan.jmx -l /path/to/results_file.jtl
your results_file.jtl content will look like:
1409124780902,182,Logon,200,OK,Thread Group 1-1,text,true,214,0
1409124781219,153,Logout,200,OK,Thread Group 1-1,text,true,110,0
where second column is page response time in milliseconds.
Other values are:
"1409124780902" - current time stamp in ms
"182" - page response time
"Logon" - sampler name
"200" - Response Code
"OK" - Response Message
"Thread Group 1-1" - Parent Thread Group name, thread number and iteration.
"text" - response data type
"214" - response data size in bytes
"0" - latency
Once your test run is done you can open JMeter GUI and load this results_file.jtl into the listener of your choice.
You might also be interested in JMeter Plugins Extras Set which is capable of generating nice looking and easy understandable response-time related graphs to wit:
Response Times vs Threads
Response Times Distribution
Response Times Percentiles
You can get it by adding Reporters.
Please keep in mind Reporters is cpu and memory intensive components and thus should not be used while actual load test.
But for sample testing you can use it and for load test run you can get response time, average,throughput etc by saving output to jtl file in JMeter.
For normal/sample run
Aggregate report gives Average response time, min, max, median etc.
Summary report also gives the same with less details,
While performing actual run you can save output of these reporters in a jtl file. After the test results can be analyzed from jtl files.
No Of Requests - 2113 ;
Average Response time (s) - 123.5 ;
Response time/Sec (90% of Requests) - 142.9
Minimum Response time (s) - 2.4
Maximum response time (s) - 14.9
Error% -0.0
My Questions - For 2113 requests average response time is 123.5 secs I need to know what will be the response time of average one single request in 2113 requests
The average response time of a single request (1 out of 2,113) will be the value itself, but I'm sure this isn't your question.
Are you simply trying to locate the response time of each request after a given test plan has fully executed, that is, to see each of the 2,113 response times? If so, just add a Summary Report to your thread group. By doing this you'll need to specify an output file (which will get generated if it doesn't already exist) and will show you in detail each of the requests sent to the server, along with the HTTP response code, response time and other goodies.
UPDATE
Per the question posed in the comments via Ripon Al Wasim, the default extension of the results file is CSV, however this is configurable in /bin/jmeter.properties:
# legitimate values: xml, csv, db. Only xml and csv are currently supported.
#jmeter.save.saveservice.output_format=csv
As we can see, JMeter only appears to support XML and CSV.
