It is clear now that i have the same problem like SOL87716, my vmware host is using Chinese language. vFoglight is a standalone pruduct, it means there are no single cartridges for download. I connected the support enginner and opened a support case, then i received a legacy vmware agent 5.5.8.1. After i installed it on my vmware host, i can receive performance data now.  Regards.
Hi. I'm starting using vFoglight to monitor my vCenter, and i can't receive performance data from vCenter. I hava installed vFoglight 6.6.1 on a Windows7 host. My vCenter is installed on a virtual machine, and the OS is Windows Server 2003. I hava installed agent manager on vCenter host. I deployed VMWarePerformance package to the vCenter host and created an agent. The agent is active and collting data. But on the VMware environment dashboard, i can't see any performance information. There is only one Virtual Center with no performance data, and no ESX hosts or Virtual Machines are found. I wonder if i have to deploy other cartridges or there is something i didn't config correctly. Can anyone help me?
