[feature/proposal] Amazon EFA collector

[Perif]

Hi,

We wrote a collector for Amazon EFA which is a high-speed network interface similar to Infiniband. 

This interface is used for tightly coupled applications in HPC (WRF, Ansys Fluent, Gromacs...) and distributed ML (think LLMs like BLOOM, OPT... or Diffusion based models like Stable diffusion). The metrics are used for optimization and troubleshooting of these computational workloads. The collector we wrote is based on the one used by Infiniband and involved changes on ProcFS as well as EFA metrics are exposed similarly.

Would the team be open for us to create a PR to add a new collector for this network interface?

Thanks,

Perif

To clarify, you are asking about adding this to the node exporter?

I am torn between "this seems very specific" and "I guess it won't hurt anyone who doesn't need it".

IMO adding support to the procfs package makes sense, whether it's then consumed by node exporter or a more specific one.

Hello Matthias,

A PR for procfs has been submitted: https://github.com/prometheus/procfs/pull/515

Regarding the specificity for the node exporter I was debating that as well in regards of the Infiniband collector which is similar. Happy to discuss it further here or Slack.

Thanks,

PY
