A layered diagram maps Linux performance observability tools to operating-system components, hardware, storage, networking, and interfaces. The joke is the overwhelming number of specialized command-line tools and the absurd complexity of figuring out which tool observes which subsystem, making it relatable as a reaction to Linux troubleshooting.
