Graphql test serveral stages and every stage have multiple request

[solaris]

three stages:
stage1:{ duration: ‘1m’, vus: 100 }
stage:2{ duration: ‘1m’, vus: 200 }
stage3: { duration: ‘1m’, vus: 300 }
and every stage have multiple post requests use graphql query
footballquery1 = query football{...}
footballquery2= query football2{...}
racingquery1=query racingquery{...}
racingquery2=query racingquery2{...}

footballquery1 and footballquery2 are same categories
racingquery1 and racingquery2 are same categories

stage1,stage2,stage3 just different vus, but they must do those four post graphqlqueries: footballquery1 , footballquery2, racingquery1, racingquery4

i want to ouput those
stage1 average response time | rate of response time < 6s | error rate(404/500) | request/sec
football
racing

stage2 average response time | rate of response time < 6s | error rate(404/500) | request/sec
football
racing

stage3 average response time | rate of response time < 6s | error rate(404/500) | request/sec
football
racing

I’m a k6 newer and I read k6 tutorials， still can’t solve this problem, please help me, thanks a lot

Hi @solaris !

Welcome to the community forums!

I think the most proper way of solving your need is using End of test.

However, you achieve something similar to your needs by using the thresholds and tags.

So the following script:

import http from "k6/http";
import { sleep } from "k6";
import { tagWithCurrentStageIndex } from 'https://jslib.k6.io/k6-utils/1.3.0/index.js';

export let options = {
    stages: [
        { target: 5, duration: "5s"},
        { target: 5, duration: "5s"},
        { target: 15, duration: "5s"},
    ],
    thresholds: {
      'http_req_duration{stage:0,sport:football}': ['avg < 200'],
      'http_req_duration{stage:0,sport:racing}': ['avg < 200'],
      'http_reqs{stage:0,sport:football}': ['count>0'],
      'http_reqs{stage:0,sport:racing}': ['count>0'],
      'http_reqs{stage:1,sport:football}': ['count>0'],
      'http_reqs{stage:1,sport:racing}': ['count>0'],
      'http_reqs{stage:2,sport:football}': ['count>0'],
      'http_reqs{stage:2,sport:racing}': ['count>0'],
    }    
};

export default function() {
   tagWithCurrentStageIndex();

   
   http.get("https://test.k6.io/", {
      tags: {sport: "football"}
   })

   http.get("https://test.k6.io/", {
      tags: {sport: "racing"}
   })

   http.get("https://test.k6.io/", {
      tags: {sport: "racing"}
   })
    
   sleep(1);
}

can produce output like:

Let me know if that answers,
Cheers!

thanks for your answer a lot.
I just add some custom metrics, group my post request and config my thresholds
is “post” method add tags to my graphql query post like “get” method.

 group("football", () => {
    const footballResponse = http.post(
      API_BASE_URL,
      JSON.stringify(footballSubgraphqlQuery),
      { headers, tags: { sport: "football"} },
    );
    footballLessThan6sRate.add(footballResponse.timings.duration < 3600);
    footballErrorRate.add(
      footballResponse.status === 500 || footballResponse.status === 404
    );
    footballRequestPerSecond.add(1/60)
  });

@solaris

Yes, it should, like any other HTTP request.
