[Verse 1] Deep within the kernel lies a treasure trove of sight Function calls and system events flowing day and night Built-in tracing infrastructure waiting for your call Ftrace is the gateway to observe them all [Chorus] Trace command opens doors wide Function flows you cannot hide Mount debug f-s proc trace See the kernel's inner space Trace command trace command Shows you where the functions land [Verse 2] Enable tracers with a simple echo to the file Function tracer catches calls that execute with style Set your filter narrow down the functions you need Trace events reveal the kernel's every deed [Chorus] Trace command opens doors wide Function flows you cannot hide Mount debug f-s proc trace See the kernel's inner space Trace command trace command Shows you where the functions land [Bridge] Buffer size controls the memory Ring buffer keeps the history Current tracer sets the mode Tracing on starts the flow Available tracers show the list Not a single call you'll miss [Verse 3] Trace-cmd record captures traces to a file Start and stop with precision keeps the data compiled Report command reads the traces shows you what occurred Function graph displays the call tree every word [Chorus] Trace command opens doors wide Function flows you cannot hide Mount debug f-s proc trace See the kernel's inner space Trace command trace command Shows you where the functions land [Outro] From user space to kernel deep Execution flows are yours to keep Ftrace and trace-cmd combined Illuminate the kernel's mind
