[Verse 1] Deep beneath the surface where the kernel breathes SystemTap awakens, probing what it sees Scripts that pierce the veil of running processes Kprobes and uprobes mapping secret addresses Translation phase converts your probe requests Into C code modules, then the kernel tests [Chorus] Hook and trace, instrument the race eBPF maps and SystemTap taps Verifier checks, bytecode protects Dynamic probing never stops Trace the calls, catch them all BPF programs in kernel space Hook and trace, instrument the race [Verse 2] Berkeley Packet Filter evolved beyond its name Virtual machine running in the kernel's frame Bounded loops and limited stack space Verifier ensures no infinite chase Perf events trigger when conditions match BPF maps store data in each catch [Chorus] Hook and trace, instrument the race eBPF maps and SystemTap taps Verifier checks, bytecode protects Dynamic probing never stops Trace the calls, catch them all BPF programs in kernel space Hook and trace, instrument the race [Bridge] Tapsets provide the vocabulary Functions wrapped for clarity BCC tools compile on demand Libbpf gives you full command From bpftrace one-liners quick To complex probes that diagnose tricks [Verse 3] Performance counters tell the hidden tale CPU cycles where your programs fail Flame graphs reveal the hottest spots Histogram buckets connect the dots Safety first in kernel territory No crashes in your debugging story [Chorus] Hook and trace, instrument the race eBPF maps and SystemTap taps Verifier checks, bytecode protects Dynamic probing never stops Trace the calls, catch them all BPF programs in kernel space Hook and trace, instrument the race [Outro] From function entry to syscall exit Every instruction you can visit Kernel mysteries unveiled at last Through instrumentation unsurpassed
