Tim's Tool team continues to deliver new tools to the community almost weekly. You can check the latest on the Tool Wiki @ http://communities.intel.com/docs/DOC-1171. Also if you have a need for a new tool please let him know by responding to the wiki.
If you are trying to use a tool and not having success please let us know as well as your feedback helps shape the tools the team works on.
I also know that Tim is defining a higher level picture of the typical IT infrastructure and how each tool can be used to troubleshoot different connection points. Stay tuned for this..
