Monitoring vCenter vctomcat with Hyperic

VMware makes some amazing things, sadly interoperability between them often seems to be an afterthought.

No amount of troubleshooting on my part could get it to work correctly. After giving it a reset its back to working as expected – yay for WiFi faster than dial-up.
