Shadow Core Tracker
● Released
Shadow Core Tracker is a real-time monitoring and alerting system built with Node.js, React, and PostgreSQL, designed to track core metrics and anomalies in distributed infrastructure. It leverages WebSocket-based streaming and a lightweight Express API to provide instant visibility into server health, resource usage, and error spikes. The project aims to simplify DevOps oversight by delivering actionable insights through a clean, responsive dashboard.
Comments
The WebSocket streaming approach is exactly where we see teams get tripped up. We had a similar setup crash under 500 concurrent connections because we forgot to implement backpressure handling on the PostgreSQL side. Did you run into any write contention issues with the real-time inserts during high error spikes?
