If you want to use an tracing tool like the one we looked at today your options are:
Get a job at Google
Build it yourself
Cobble together what you need out of existing tools
Not quite, dtrace has existed in an open source form for over a decade and, while it does not produce those images, provides the tooling needed to create them. If you want to use dtrace now, it exists on Solaris/illumOS, FreeBSD, and OS X. Linux is, unfortunately, way behind these platforms in ability to introspect what is going on in your system, but there are a few ongoing attempts to port dtrace to Linux although I don’t know their state.
