I am having trouble writing a class to query for the cpu usage when you pass in a host and the required information. Does anyone have a sample code or a guide on how to write such a program?

Thanks

You can retrieve the below properties from Host object to get the cpu utilization and overallmemoryusage

summary.quickStatsoverallCpuUsage

summary.quickStats.overallMemoryUsage

Thanks

Take a look here: http://www.vmware.com/support/developer/vc-sdk/visdk400pubs/ReferenceGuide/vim.host.Summary.QuickStats.html

The vSphere API reference doc is your friend

If you're new to the VMware SDK/API's, please spend some time going over this doc: Getting Started with vSphere SDKs

Hi,

In order to retrieve the the HostSystem managed object, you can use findByDns or findByIp API to get the HostSystem. Then you can drill down to the overallCpuUsage property ( HostSystem->summary->quickstats->overallcpuUsage) to get the overall cpu usage of the host.

You might want to refer to the sample SearchIndex.cs, shipped with the vSphere SDK package, which demonstrates how to use FindByDns and FindByIp APIs.

Hope this helps.
