Dtrace Review

[jrdohmen]

Used to admin a few Sun boxes in the 90´s. Don´t do that anymore, but I really wish I had a tool like this!

Quite funny and knowledgeable, but unfortunately to advanced for me...

it starts at 10:00 ;-)

18:00 - dtrace -n syscall:::entry'{trace(execnam­e)}'

20:00 - dtrace -n syscall:::entry'{@[execname] = count()}'

21:20 - dtrace -n syscall:::entry'/execname == "iTunes"/{@[probefunc] = count()}'

22:30 - dtrace -n syscall:::entry'/execname == "WebKitPluginHos"/{@[probefunc­, pid] = count()}'

23:00 - dtrace -n syscall::read:entry'/execname == "WebKitPluginHos"/{@[ustack()] = count()}'

Hello all, are there any other nice tools for tracing OS calls in different linux system,

or better i should say a comprehensive tool suitable for all Unix based OSs.

SystemTap is Linux's version of Dtrace

Strace also traces sys. calls but inner workings are completley different and really slow.

I would like a similar talk using a leopard box. There is limited material about it and not so interesting. The very interest of dtrace is to interactively run queries to get understanding of a problem. Runny canned query is less interesting and most of them are currently Solaris specific anyway. Apple, please invite Cantrill to do a similar talk.

well, dtrace is here, im probing around on my leopard box.

dtrace on a mac is very sexy. The instruments stuff is neat as hell.

Great talk, can't wait for dtrace on osx.
