Yes, we have other tools, but some people do not know or use or install these tools. I was hoping this one would be able to display a number of things to help the developer and us in helping them debug problems.

Well I did create something else :-) As for pointing to existing tools, we should do that anyway in the documentation.
>Or call existing tools from a small script?

Calling the existing tools could be a problem as they may not be installed, but they could install the tools too after the script points it out.

>Is it the DPDK focus to develop and maintain such tool?
I can not answer that question per say. I can at least be the maintainer for this script or someone else.

I think we need something that pulls all of the information from the system for the developer to see at a quick glance to help debug his system. Also we can then say run this script and post to the list, which is nice and simple as a debug aid.
