# speed-logger

Runs periodic internet speed tests using the Cloudflare speed test API and visualizes the results in Grafana. Tests run every 15 minutes and record download speed, upload speed, latency, and jitter. Results are stored in a SQLite database and displayed on a pre-configured Grafana dashboard.
