I have installed the Hyperic 4.4 Enterprise (4.4.0-EE build #1509 - Jul 28, 2010 - Release Build) demo from the website to test support for monitoring VMware vSphere 4.0.
I installed a Win32 agent on the W2003 server that is hosting the vSphere vCenter 4.0U2 server and configured it. Once the resources were configured, I edited the VMware vCenter resource to add a valid user/password and after a short while the ESXi host servers and VMs showed up in the Browse/HQ vSphere screen. That all works fine.
I then tried to add a different vCenter server with it's own ESXi host servers (with a new agent installed on this server's W2003 ) and that's where the problem starts. After I add the userid/password in the vCenter Inventory details, the new ESXi hosts and VM start to show up under "Recently Added". When I switch to the Browse/HQ vSphere screen the original vCenter has gone and a mixture of the other vCenter's host servers and it's own host servers appear under the newly added vCenter.
Should I be able to monitor 2 different vCenter servers?
