"The Intel Open Source Technology Center is pleased to announce the release of version 0.1 of LatencyTOP, a tool for developers to visualize system latencies. Slow servers, skipping audio, jerky video - everyone knows the symptoms of latency. But to know what's really going on in the system, what's causing the latency, and how to fix it... Those are difficult questions without good answers right now. LatencyTOP is a Linux tool for software developers (both kernel and userspace), aimed at identifying where system latency occurs, and what kind of operation/action is causing the latency to happen. By identifying this, developers can then change the code to avoid the worst latency hiccups."

Dtrace's license is not compatible with the license of the linux kernel. So we have to wait until either Linus decides to go for GPL v3 or Sun allows DTrace to be used in the linux kernel...
You might want to read through the comments here:

which was also discussed on osnews here:

Based on everything I know about the issue, the actual stopper for DTrace on Linux is Not Invented Here Syndrome. License discussion led to debate about what is or isn't considered a derived work of the kernel, and ways Linux can work around that to include DTrace.
