Metrics not being computed when the application is forked into a child process about nestjs-prometheus HOT 5 CLOSED

Is this something that works using prom-client directly?

It could be something related to prom-client since it is a dependency of this lib but I'm just using the methods exported by nestjs-prometheus directly as you can see here

Maybe prom-client does not support child process ?

Before I look into anything here, you will need to confirm the behavior of both prom-client and NestJS when it comes to child processes.

Given this library is a simple thin wrapper around prom-client, it's unlikely the issue would be here. But before I do any work to figure it out, you will need to confirm that the underlying libraries support child processes as you'd expect and then we could say with certainty that something in this library was preventing that from working.

Looking into prom-client repo I found that they are trying to add support to this

siimon/prom-client#403
siimon/prom-client#401 (comment)

So yeah, definetly not something in this library

Great! Thanks for looking into it. If they ever get support added and it still doesn't work, please feel free to re-open this issue.
