[Lse-tech] lockmeter tool available

[Rick L. <ric...@us...>]

For those of you frustrated by the order that lockmeter sorts in, I've
written a perl script which will help you reorder it into something
interesting (usually, for me, descending %age contention is more
interesting than alphabetically by lock name). It can be run on
existing lockmeter output or as a filter during generation.

"locksort" is about 20K or so, which is borderline "big" for a mail
message.  Email me if you'd like a copy, and if there's sufficient
interest I'll put a copy out on sourceforge.  Ideally, this should
probably end up paired with lockmeter itself so I'm hesitant to put
another copy anywhere else just yet.

    locksort [-s [+]N] [-r [+]N] [-w [+]N] [file]

    specifying field N (first field is 0) sorts ascending
    specifying field +N sorts descending

    -s N specifies the spinlock section
    -r N specifies the read portion of the rw lock section
    -w N specifies the write portion of the rw lock section
