Lightweight Linux system statistics CLI
kernstat is a lightweight command-line tool for monitoring Linux system performance. It reads kernel statistics directly from the /proc and /sys interfaces, with no external monitoring daemons, subprocess calls, or third-party dependencies for data collection.
kernstat reports CPU usage, memory consumption, disk space and I/O, network throughput, and per-process statistics. Each command offers human-readable output for interactive use and structured JSON output for scripting, automation, and monitoring pipelines.
A live updating dashboard displays all key system metrics in a single refreshing view, and a TOML configuration file lets you set defaults such as the sampling interval and output format.
Available commands:
- kernstat cpu: CPU usage percentage
- kernstat memory: memory usage statistics
- kernstat disk: disk space and I/O rates
- kernstat network: network throughput
- kernstat proc PID: per-process statistics
- kernstat report: full system report
- kernstat dashboard: live updating dashboard
kernstat runs under strict confinement and requires no additional interfaces. All functionality, including per-process inspection, works within the default snap sandbox. This makes it a safe, minimal footprint utility for servers, containers, and minimal Linux systems.
