But this I am using a while loop to run a API request until a specific response is recieved (eg. Of course the throughput will be lower if the server is not capable of handling it, or if other timers or time-consuming test elements prevent it. I want to generate a report with jobID, status and the time taken. Since Jmeter is including failed response times along with passed one for avg response calculation. If the avg response time of your requests is 1 second (assuming you have only 1 requests in your test plan), then you will be able to hit total 264000 (264000/240 = 1100 requests per second) for the last 4 mins (when all of your Constant throughput Timer : Target throughput- 60, Calculate Throughput on -All Active threads. The larger file is, the larger difference between response time and latency will be As per JMeter documentation: Min - The shortest time for the samples with the same label. 3. so how can i calculate the exact response time? i am implementing above logic to find bottle neck, i need to prepare a report with bottle neck. You may be interested: Performance Elapsed time. 90% Line (90th Percentile) is the value below which 90% of the samples fall. jmx -l result. getResponseDataAsString()); Use then this response as ${response} where you need it I've done a lot of tests in JMeter for REST Api using HTTP Requests and sql testing with JDBC Requests. The active threads at a certain time/Average response time of all these active threads Say I have data as below: The chart shows a duration of stable pressure hit server, 3 clients in total have 1050 threads at any time of the duration, so the TPS is(if the average response time is still 0. getTime() Instead of creating/updating a report yourself for each call, you can create a report at the end of the test using the JMeter result file. jmeter -n -t path_to_jmx_file -l path_to_jtl_file it'll produce CSV output file. It is expected behaviour as you increase the load generation you will see the downgrade in the performance depends upon your host. As a workaround you can add a JSR223 PostProcessor and divide Connect Time, Latency and Elapsed Time by 1000, this way you will have these metrics in seconds.
