Http_req_failed possible to get more detail?

Grafana k6
1

Hi :grinning:
I am getting a lot of http_req_failed…: 66.98% ✓ 537704.
How can I dig deeper and find out what error code they are issuing, why does K6 only gives you a total number and percentage?
Would it be possible to get more details?
I used k6 run --http-debug=full script.js but it did not help.

Hi fatkobra,

It seems like this answer here is what you might be looking for. Could you check it out let us know whether it solves your issue?

This document might help as well. Also, this one.

Thanks.

Hi @inanc ,

Thank you so much for your help. I read the 3 articles you suggested but I had already used the debug option --http-debug=full, but it did not give more detail.

However, I increased the number of Kubernetes pods from 2 to 10 pods, and the problem is one.

I had very high latency with 2 pods and the timeout was smaller.

iteration_duration.............:       max=35.02s
