title: EPF cohort 4 Week 16 update

# Week 16
## TL;DR
As we are all heading to DevConnect, this will be a shorter presentation than usual.

Wrapping up my projects, preparing the presentation, preparing the last dev update, rerunning the version of Lighthouse with my changes on Goerli. 

## Exposing Validator Missed Block Metrics
### Context
I recently updated and recompiled the latest version of LH to generate new charts for my upcoming project presentation at Istanbul DevConnect on Friday. Additionally, I configured the validator monitor with 15,000 keys for tracking, ensuring we'll have ample data for our presentation's charts. During this process, I noticed LH was generating numerous warning messages. Upon closer investigation, I discovered an issue with the log message implementation. Michael Sproul had also identified this problem and submitted a [pull request to address it](https://github.com/sigp/lighthouse/pull/4922). Michael's fix is successfully eliminated the warning messages.

As soon as the metrics start rolling in, I plan to update the [lighthouse metrics dashboard](https://github.com/sigp/lighthouse-metrics/pull/44). I previously created. This update is crucial as it doesn't currently include the latest metrics incorporated into LH. My goal is to ensure that the data in my graphs is current and accurate, making this likely the final update I'll need to make before the presentation.  

## Attestation Simulator
### Context
I wrapped up the [PR](https://github.com/sigp/lighthouse/pull/4880) with Paul's feedbacks. I am waiting for a new round of feedbacks so I can finalise it. I am planning on adding a dashboard to lighthouse-metrics once this is approved and ready to be merged.
