# EPF5 Week-14: Teku metrics implementation

## Week overview
- [X] Worked on Teku metrics
- [X] Reviewed my Lighthouse and Grandine PRs
- [X] Had a call with Lighthouse team

This week, I continued implementing metrics in different clients focusing mostly on Teku.

## Lighthouse
I had a call with Jimmy where we discussed the values of the metrics we already have, how to better present them, and what else could be helpful. We decided to break the draft PR into smaller PRs to get them merged, and I pushed [the first one](https://github.com/sigp/lighthouse/pull/6381).

## Grandine
I got the review from Hangleang on [my Grandine PR](https://github.com/hangleang/grandine/pull/1), We discussed some implementation details, and I am proceeding with the changes.

## Teku
Most of the week was spent working with the Teku codebase. I set up Git properly as I need to work with the original repo (for WIEP) and its fork (Nashatyrev). As this was my initial PR into it, I needed to dive into the metrics implementation on Teku. Every client has its own way of implementing metrics. I started with two PeerDAS metrics and made [my first metrics PR](https://github.com/Nashatyrev/teku/pull/139). My goal is to compare metrics across different clients. I am close to achieving this. Soon I will be able to compare Lighthouse and Teku and build a summary dashboard that brings clarity on how PeerDAS works on different clients.
