VMware recently released a technology preview of vCenter Administrator Portal (vCAP) over on the VMware Communities site. vCAP is a web based console that allows a central view into your VMware environment across mutliple vCenter Servers and allows you to monitor events and alarms,search and track inventory, or connect via the VI Client to any vCenter Server.
You can download the preview (beta) of vCAP as an full installable image, an appliance, or OVF. Just keep in mind that it is a technology preview, so make sure you provide your feedback about things that don’t seem to work or work right.
(Thanks to JJ and Matt for making me aware of this!)
