Sysmon-CLI: Building a Cross-Platform System Monitor

System monitoring is harder than it looks. Different OSes expose metrics differently. Polling too often wastes CPU. Too slow misses spikes.

Design Goals

For Sysmon-CLI, we set clear goals:

Architecture

The Core Engine (Go)

We chose Go for several reasons:

Platform-Specific Collection

Each OS requires different syscalls:

We abstracted these into a unified interface.

Efficient Polling

Instead of naive polling, we use:

Export Flexibility

Sysmon-CLI can export to:

Performance

On a typical system:

This lets you monitor continuously without impacting workload.

What's Coming

We're adding:

Sysmon-CLI is open source. Contributions welcome!
