ESX 4.x
VMWare supports SNMP on ESX through the use of the net-snmp agent – see VMWare’s SNMP on 4.x docs for details. An example snmp.conf file:
syscontact yourname@yourdomain.com syslocation Datacenter, Rack 32, U2 rocommunity public proxy -v 1 -c public udp:127.0.0.1:171 .1.3.6.1.4.1.6876 proxy -v 2c -c public udp:127.0.0.1:171 .1.3.6.1.4.1.6876

Matthew White has written a quick and to the point article on enabling SNMP on ESXi – you can read it on his blog.
