Load testing with Artillery

[YaphetKG]

I was using a very simple artillery config

config:
  target: "{{ $processEnvironment.SERVER_URL }}"
  http:
    timeout: 60
  ensure:
    maxErrorRate: 1
    p95: 2
  phases:
    - duration: 15
      arrivalRate: 10000
  plugins:
    expect: {}
scenarios:
  - flow:
# test normalized nodes post
      - get:
          url: "/docs"

But after running the test I get a lot of errors

EADDRNOTAVAIL	51942

In the report html artillery outputs.

Hi @YaphetKG 👋 this is an operating system level error rather than an issue with Artillery. Your phases definition is creating 10k new virtual users (VUs) per second. Each of those is a new TCP connection, so the most likely reason for the error is running out of ephemeral ports.

If you're not trying to stress test the TCP stack on your OS, I'd suggest using loop to send multiple requests from each individual VU and reduce the arrival rate accordingly: https://www.artillery.io/docs/guides/guides/http-reference#loops

Thanks @hassy
