TL;DR

BCC is a toolkit for watching what's happening deep inside a Linux system in real time, running lightweight monitoring code directly in the kernel via eBPF instead of slowing the system down.

Why would anyone build with this?

REASON 1

Measure disk I/O latency on a live server using the biolatency tool.

REASON 2

Track when programs open new network connections with tcpconnect.

REASON 3

Find memory leaks in a running application using memleak.

REASON 4

Profile which functions are consuming CPU time on a production server.
