## What it is
bpftune is a daemon that uses eBPF observability to continuously monitor Linux system behavior and automatically adjust kernel tunables such as sysctl parameters. It tunes at a fine grain (per-socket, per-device), logs what it changed and why, and steps aside when administrators set values manually.

## Use cases
- automatically tune Linux kernel sysctl parameters without manual configuration
- optimize TCP network performance on servers with no human admin access
- continuously adapt system tunables to changing workloads using eBPF observability
- replace static 'magic number' sysctl configs on cloud instances
- log and explain every tuning change made to the system

## When to choose
- you run many unattended Linux servers ('cattle not pets') that need ongoing performance tuning
- you want zero-configuration auto-tuning with explicit logging of changes
- you need fine-grained tuning (per-socket, per-device) rather than system-wide static settings

## When to avoid
- you need strict, deterministic kernel configurations that must never change automatically
- your kernel or environment lacks eBPF support
- you run non-Linux systems, as bpftune is Linux-only
