That's indeed a useful list. lsof alone covers a lot of ground! Mac OS X has a pretty nice set of DTrace scripts built in: http://dtrace.org/blogs/brendan/2011/10/10/top-10-dtrace-scripts-for-mac-os-x/ http://dtrace.org/blogs/brendan/2011/10/10/top-10-dtrace-scr... The ones I use the most: * iosnoop: see all disk I/O. especially useful to find disk-chatty/poll-y apps. * execsnoop: see new processes being spawned. * opensnoop: see file opens. especially useful for failed file opens that break an app. * dtruss: see all system calls. get access to the entire OS interaction history of an process (or app). * errinfo: trace failing system calls. where there is smoke... * iotop -- who is using disk There is just a crazy, crazy list of things available, built-in: man -k dtrace Edit: wow HN formatting sucks so bad. I wish I could make that list more readable, but apparently I can't.

IMHO, dtruss output is rather useless because hardly any of the arguments are human-readable.

  That's true, but for getting a timeline of what happened, it's just the right tool.

You'll take your low-overhead-and-proud design and you'll like it. (that said, your post is very readable)

- Four spaces at the start of a line makes 'preformat', useful for code or lists. - You'll want to manually wrap long lines, though.

  Two spaces are actually enough. But I don't want my descriptions to look like code! Ideal for this example would be a table where the first column is formatted as code, and the second column as text.
