Access built-in metrics mid test

Grafana k6

Hi,

Is there a way to access the built-in metrics during test execution so I can put some logic if certain criterias as met.

For example, I need to stop the test execution if I have reached 100k http reqs, in this case I need to access the http_reqs metric!

Hi @rdt.one!

I don’t think, you can access it by default, but you can definitely do it with an extension.
PoC:
With this extension GitHub - bandorko/xk6-metrics
You can access the needed information like this:

import http from 'k6/http';
import metrics from 'k6/x/metrics';

export const options = {
  discardResponseBodies: true,
  scenarios: {
    scenario1: {
      executor: 'shared-iterations',
      vus: 1,
      iterations: '10',
    },
  },
};

const httpReqs = metrics.registry.get('http_reqs');

export default function () {
  http.get('https://test.k6.io/');
  console.log('http_reqs:' + httpReqs.sink.value);
}
