What did you do?

Installed prometheus with empty prometheus.yml file and observed gogc being set to 0

What did you expect to see?

As per prometheus documentation, gogc value will be set to 75 by default

By configuring explicitly gogc runtime to 75, usage of cpu is less after reloading the config

What did you see instead? Under which circumstances?

Gogc value is being set to 0 , instead it should set to 75 by default
