# EPF5 Week-8: Dashboard review

## Week overview
- [X] Received DevOps review of the PeerDAS dashboard.
- [X] Corrected the dashboard based on the review.
- [X] Had a call with the Lighthouse team.
- [X] Started implementing PeerDAS metrics in Lighthouse.
- [X] Finished the overview of LH metrics.
- [X] Explored Beacon API for blobs and discussed potential data column API.

This week, I focused on reviewing my PeerDAS dashboard. I submitted the dashboard to the DevOps team and the Lighthouse team (Jimmy), received feedback from them, and made the necessary corrections on the dashboard. Additionally, I initiated work on the custody metric.

### Dashboard review
The DevOps team reviewed my dashboard and suggested several improvements, such as filtering by type or renaming certain elements. I implemented these recommendations and resubmitted the dashboard for a second review.


### Lighthouse metrics
I had a call with the Lighthouse team to discuss the metrics and explore the codebase, focusing on the metrics I should begin with. I initiated the implementation of the custody metric, made my first commit and identified the need to work on gossip and libp2p metrics as well. In the process, I discovered the [Beacon metrics repo](https://github.com/ethereum/beacon-metrics/blob/master/metrics.md), which may require updates.

### Beacon API
An API for retrieving blob sidecars [getBlobSidecars](https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Beacon/getBlobSidecars) has been already implemented before. This API fetches blob sidecars for a specific block ID. Core developers have discussed the possibility of deprecating this API and introducing a new endpoint called `data_column_sidecars`. However, no final decision has been made regarding this change.
