Metrics
Real CloudFront edge metrics for this site — measured live from AWS CloudWatch, refreshed every hour.

How it works
This dashboard is part of my Cloud Resume Challenge — a fully serverless pipeline that reads this site's own traffic from AWS and shows it live.
The pipeline
- ▸A CloudFront distribution serves the site from the edge
- ▸CloudWatch collects request, transfer and error metrics
- ▸An AWS Lambda queries CloudWatch and formats the data
- ▸API Gateway exposes it; this page fetches it live and refreshes hourly
What it measures
- ▸Edge requests — every HTTP hit (pages, assets, bots)
- ▸Served 2xx — an estimate of real, successful responses
- ▸Data transferred out of CloudFront
- ▸4xx rate — mostly bot/scanner probes, shown separately
- ▸5xx rate — real server errors (drives the health status)
