To explain this example in more detail: The profiler periodically interrupts software execution, and for those disconnected stacks it happens to be the execution of the kernel software ("vfs*", "ext*", etc.).

Syscall count by program bpftrace -e 'tracepoint:raw_syscalls:sys_enter { @[comm] = count(); }'. bcc is powerful but laborious to program. Internally, bpftrace uses a lex/yacc parser to convert programs to AST, then llvm IR actions, then BPF. in 2004, so I have to think back to that time to understand it. eBPF does more.

meme originated in IT’s transformation from manual system administration to automated configuration management and software deployment. These changes sound like something that we’ve often talked about in software development: continuous integration and continuous delivery. We’ll see it in banking. Automating this process is simple.
