Microsoft has a new product to keep track of your diskspace with te use of Visio.
The Visio 2010 add-in for Disk Space Monitoring provides a graphical view of free space available in the server machines on a network. This add-in has a client and a server component. The client component requires Visio professional 2010 or Visio Premium 2010 and the server component requires SharePoint Server 2010. The client component of the add-in uses the new data graphics feature of Visio 2010 to display the results of server monitoring and integrates with the System Center Operations Manager 2007 to get the disk free space details. The server component makes it possible to publish the data linked diagram to SharePoint Server 2010 and refresh it in real-time for broader consumption.
The Visio Add-in for Disk Space Monitoring is available for download at the Microsoft-website. There is a x86 and a x64-version, both are 2MB in size. Besides the add-ins Microsoft also offers through the site a clear how-to for the installation and use of the Add-in.
