## What it is
BPF Compiler Collection (BCC) is a toolkit for writing efficient eBPF-based kernel tracing and manipulation programs, with instrumentation in C and front-ends in Python and Lua. It ships with a large collection of ready-made tools for Linux I/O, networking, and performance analysis.

## Use cases
- trace disk I/O latency on Linux
- profile kernel function performance with eBPF
- monitor network traffic at the kernel level
- write custom BPF tracing tools in Python
- debug slow syscalls on a production server
- histogram block device I/O sizes

## When to choose
- you need low-overhead kernel instrumentation on Linux 4.1+
- you want ready-made tracing tools plus a framework for custom eBPF programs
- you're doing performance analysis or network traffic control on Linux

## When to avoid
- you're on a non-Linux platform
- you need a higher-level observability product rather than a tracing toolkit
- your kernel is older than 4.1 and can't be upgraded

## Facets
- artifact type: library
- maturity: active
- function: monitoring, tracing, developer-tools
- domain: developer-tools, performance, operating-systems, networking
- platform: python, cpp, cli
- tags: ebpf, bpf, kernel-tracing, observability, performance-analysis, kprobes, system-instrumentation, linux
