Hi,
For those who want the power and flexibility to design their own health monitoring solutions, VMware
supports the following protocols. Two of them are industry‐standard protocols, and one is a proprietary API
designed specifically for managing vSphere datacenters:
CIM (Common Information Model)
SNMP (Simple Network Management Protocol)
vSphere Web Services API (WS API)
This technote http://www.vmware.com/files/pdf/techpaper/hwhm41_technote.pdf helps you to understand what's is CIM and purpose of it.
