The following are the pre-requisites for an ESX server discovery and monitoring:

  • VMware SNMP agent should be enabled on the ESX server.

  • Cisco Discovery Protocol (CDP) should be enabled on both the ESX server and the physical switch.

  • DNS server should have an entry mapping the ESX server name to its IP address.

  • Do not enable the Net-SNMP Agent. Enable only the VMware SNMP Agent. If the proxy VMware SNMP Agent / Net SNMP Agent is enabled, the ESX server will be classified as a Linux Host and is treated like any other Linux host.
