Transaction Response time

Grafana k6 OSS Support

Hi Team,

New to K6, is there is a way to get individual transaction (group) response time like avg, median, min, max, and percentile.

  1. In the init section define your measurements.
const Login = new Trend('01Login');
  1. after the call assign a value to the measurement
const loginResponse = http.post(loginUrl.toString(), loginPayload,{loginParams,responseCallback: only422callback});
Login.add(loginResponse.timings.duration);
  1. at the end of the test the summary will report on the measurement, alongside the default metrics

Thanks, @BobRuub . How do we add the response time of multiple request timings to a single transaction?
Ex 01_Transaction=resp duration Req 01 + resp duration Req 02 + resp duration Req 03

Also how to handle the parallel request

Yes, adding the durations works if that’s what you require.

never used it myself but http batch seems to be what you are looking for…

Hi Gerard,

I am also looking for the same response time calculation. I you have the solution for this, can you please share the same?
