I was sitting waiting on a session about the VMWare VIX API and was talking to a VMWare developer <strong>Ravi Cherukupalli </strong>and he introduced me to a free tool called the VMWare Guest Console.  This tool connects to a host, virtual center, or machine and allows you to see and act on the processes within the machine, navigate the file system, do the typical VMClient functions (Snapshots, Power Cycles, Management).  The cool thing about it is that it provides all this functionality by implementing the APIs so you don't have to log into the console of each machine to kill a particular process or access the file systems of the machines.  Definitly worth checking out at <a href="http://labs.vmware.com/flings/vgc" target="_blank">http://labs.vmware.com/flings/vgc</a> and connecting it to your environment.  If you are an engineer it can maintain a list of connections and connect to several environments as you bounce around between customers.  Let me know what you think about it in the comments.  For me, it is a very handy tool especially if you are looking for process and performance data across multiple virtual machines and want to do it quickly.
