    SubjectRe: DTrace-like analysis possible with future Linux kernels?

    Maybe, but DTrace seems to solve one really pressing problem: tracking
    disk I/O to the processes causing it. Unexplained high I/O
    utilization is a *very* common problem, and there aren't any tools to
    diagnose it.

    Most other system resources can be tracked quite easily: disk space,
    CPU time, committed address space, even network I/O (with tcpdump and
    netstat -p). But there's no such thing for disk I/O.
