DExplorer

I've just uploaded dexplorer ver 0.75, and it's shaping up to be quite a useful tool.
It runs a series of DTrace scripts that monitor generic system activity, and saves the output in a .tar.gz file with a meaningful structure,

The idea came from David Visser, Christopher Wells, and several other guys I met while in Melbourne, Australia last week. It's a great idea - it makes a lot of sense.

Here I've expanded a .tar.gz file created by dexplorer to demo the contents,

Lots of goodies to pick over.

The names of the files should indicate their contents. Many of them contain quite generic data, the idea is that one dexplorer file should contain as many statistics as possible.

Check for updates. I'll also throw it in the DTraceToolkit.
