The pieces necessary for dtrace all ship with opensolaris by default. If you have opensolaris, you already have DTrace. The sources are in several places inside the opensolaris tree. A good place to start might be: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/dtrace/ and http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/dtrace/ @ ashish

Can you please point me to the source/binaries? I looked for dtrace, but all I find is DTraceToolkit, and I don’t seem to find the actual dtrace executable inside it.

I tried it on one of the PL/SQL parser I was writing on Ruby (just for getting used to Ruby). Very helpful. Only problem is that it is damn addictive, just like Ruby itself. ;-) Ananth, this is impressive. I tried it on one of the PL/SQL parser I was writing on Ruby (just for getting used to Ruby).

In case of java, you would use the hotspot$pid:::method-entry and hotspot$pid:::method-return probes to track function calls. @ Sundar,

I would be interested to see how it generates a graph where a java class is making a call to a native class written in C++. If you have a sample, please post.
