What is an XPerf alternative for Linux and Mac OS X?

XPerf is a tool that allows you to take a detailed trace of various system activity like CPU, I/O and more...

Because of it's detail you can see stack trace counts, disk position offset graphs, driver calls and so on...

Is there a XPerf-a-like alternative for Linux and Mac OS X? What are the top-notch performance tools there?

For linux you can combine many tools. top (or htop), iotop, etc. You could also install BSD accounting and use the sa command.

1Some (or all?) of accounting is also available on OS X. – Daniel Beck – 2011-03-26T14:54:24.217

For OS X, look into dtrace and derived tools (I think fs_usage and sc_usage are related; there's also a Linux port), as well as parts of Apple's Developer Tools such as Shark (see e.g. here and here).

Check out Instruments for the new version.

Instruments is the closest to xperf

fseventer is an excellent GUI filesystem monitor for OS X (support until 10.9 Mavericks, 10.10 Yosemite yet unsupported) . It uses the Spotlight API, and often helped me to determine undesired write activities, or determine which config files are indeed read in, etc.
