Hi @ArthurSens! Hi @dashpole! I am eager to be a part of this project and looking forward to work under your mentorship and guidance. Are there any pre-requisites / pre-tests for the selection process of mentees ?

Hi Adwait, glad to see your interest. There are no pre-requisites or tests, just make sure to apply following the LFX process. Also be aware that our proposal is still just a PR, we still need both CNCF and LFX to approve the mentorship

Hello @ArthurSens ! I am looking forward to contribute to this project. Can you please guide me on how to get started?

A good starting point is understanding Remote-Write and the OTLP->Prometheus compatibility spec. If you few comfortable tackling some of the checkboxes above, that's also nice :)

Hey @ArthurSens, Hanshal here. I am an open-source developer contributed to various projects like Buildsafe, Glasskube, Cyclops and a couple of Apache's too. I am currently interning at CloudRaft as a DevOps Intern. I recently published a blog on OTel Auto Instrumentation, and my curiosity towards observability brought me here. I'm looking forward to working on this issue if it gets accepted.
I am pretty much aware of the OTLP -> Prometheus spec; what else should I focus on more to understand the issue in a better way?

Thank you.

Hi Hanshal, this project is quite simple so we're not requiring that much experience, to be honest. There's nothing else to be familiar with besides the two protocols that were already mentioned: Prometheus Remote Write and OTLP.

We'd love to mentor someone who hasn't had a chance with OSS yet and is excited to participate in the community, that's all.

Anyone interested, just make sure you follow the LFX process correctly.
