Get timings for an HTTP metric
To access the timing information from an individual HTTP request, the Response.timings object provides the time spent on the various phases in ms
.
One use case of this is to use the timings in a Custom metric to make a trend for a specific endpoint.
The timings are as follows:
- blocked: equals to
http_req_blocked
. - connecting: equals to
http_req_connecting
. - tls_handshaking: equals to
http_req_tls_handshaking
. - sending: equals to
http_req_sending
. - waiting: equals to
http_req_waiting
. - receiving: equals to
http_req_receiving
. - duration: equals to
http_req_duration
.
This script gets the request duration timing for a specific GET request and logs it to the console.
JavaScript
import http from 'k6/http';
export default function () {
const res = http.get('https://httpbin.test.k6.io');
console.log('Response time was ' + String(res.timings.duration) + ' ms');
}
The expected (partial) output looks like this:
bash
$ k6 run script.js
INFO[0001] Response time was 337.962473 ms source=console
