Linux Resource Tracker: Lightweight Linux Monitoring

Sometimes I just want to know what my Linux server is doing, without spinning up Grafana or digging through dmesg logs.

I built this while working at AlphaPoint, where lightweight tools were essential for monitoring crypto infrastructure without adding performance overhead. I wanted an on-demand way to check system stats: CPU load, memory usage, disk space, network I/O.

The Fix: Python + psutil

I wrote a script that:

✅Uses psutil to grab system metrics: CPU, RAM, disk, uptime
📋Formats output for easy scanning or parsing
⏰Runs via cron, CLI, or as a quick health check script
📧Saves to local file or emails on threshold breach

Perfect for resource-constrained instances or just when you want clarity without clutter.

What Changed

⚡Quick visibility into system spikes across environments
🔍Caught silent memory leaks in long-running apps
🐛Helped debug slowdowns without setting up new tools

Good observability does not need to be heavy. This script saved me more than once when top was not enough.

Tradeoffs I Made

🖥️CLI-based to avoid storage and infra bloat: no persistent dashboard
🧹Pure Python: did not rely on Telegraf or a daemon agent
🔔Threshold-only alerts: less noise, more signal
