What are some of the open source tools that you are referring to? Within a few hours, I can imagine it being difficult to integrate and deploy your tools into an existing stack. But if you are tapping into some mirrored network port, that would make more sense.

Hello Matt - I deliberately didn't name any tools, as the ones I worked with are no long in the tooth and were $$$. What I wanted to do was bring to the OP some concepts that they might search for in order to identify the right tool for their purpose. To your point - yes, some of the tools I used made use of the kind of network port mirroring similar to what it appears you developed at Amazon. Others instrumented various virtual machines, others used various external monitors.
