Feature Request: Filter Processes by RAM or CPU Usage

[IgorOCosta]

I am currently using Process Exporter to collect metrics from a system with a large number of processes. However, this causes high resource usage because every process is being monitored. To optimize this, I would like to filter which processes are collected based on their RAM or CPU consumption.

Feature Request

Would it be possible to introduce a feature that allows filtering processes based on:

• RAM usage (e.g., only collect processes using more than X MB of memory)
• CPU usage (e.g., only collect processes using more than X% CPU)

This would help significantly in environments where only the most resource-intensive processes need to be monitored, reducing overhead and improving performance.

If this feature is already possible in a different way, I would really appreciate any guidance on how to achieve it.

Thanks for your work on this project! 🚀

I'm also looking for a similar feature.
The use case I've got is monitoring a postgres instance trying to find how where it's leaking memory.

I have a config which tracks every process, but because some connections restart very frequently, it produces lots of timeseries over time - I really only want to track the processes that are using more than ~30mb of RAM, or probably better, only track the processes that have been alive longer than ~10minutes.
