Hi there! Welcome to my blog. My name is Ivan. I am a Dutch IT Professional working as Principal IT Consultant. ESX 3i host server has sensors builtin that allows you to monitor the health of the following host components:
CPU processors
Memory
Fans
Temperature
Voltage
On systems without IPMI, only CPU sensors are available. Storage sensors are available only on systems with an LSI MegaRAID controller installed. If a particular component cannot be monitored on a given host, that component does not appear.

CIM-based framework & SNMP are available for hardware monitoring in ESX 3i. For more information check out this document.

There is no SNMP get support for trending in ESX 3i. The only thing you can do with it out of the box is send SNMP traps to a target to alert you when something is going wrong. No SNMP gets = no trending analysis via SNMP. If you want to that you will have to purchase Virtual Center or utilize the RCLI kit from VMware and pull the data out of ESX3i via Perl scripts.
