Monitoring Infrastructure Setup

[jennijuju]

Establish a centralized monitoring infrastructure to collect metrics from nodes for real-time monitoring and analysis.

[Kubuxu]

We need to deploy grafana to collect metrics.

This issue is actually two things:

• grafana dashboard setup + prometheus metric scraping to populate it; This is done.
• standalone observer node implementation which I think @Kubuxu is working on.

I am going to adjust this issue to only capture the former, and create a new issue for the latter.
