vMetrics is a small plugin for WordPress that works in conjunction with a PowerCLI Updater Script. You install the plugin, add the Widget to your sidebar in WordPress, configure which stats you would like to show, then run, or schedule the PowerCLI script against a standalong ESX/ESXi host, or vCenter server.
I have been working on this in my evenings whenever I find spare time over the last couple of weeks. It is based off Nicholas Weaver’s excellent WP-vSpherestats plugin, but has been re-worked to be more customisable, offer more metrics and statistics about your vSphere environment, and offers a PowerCLI Updater script, meaning you can easily change or customise the information that is brought back into the plugin.
