Using SNMP with Guest Operating Systems
You can use SNMP to monitor guest operating systems or applications running in virtual machines.
The virtual machine uses its own virtual hardware devices. Do not install agents in the virtual machine that
are intended to monitor physical hardware.
Procedure
u
Install the SNMP agents you normally would use for that purpose in the guest operating systems. No
special configuration is required on ESX.
VMware MIB Files
VMware MIB files define the information provided by ESX/ESXi hosts and vCenter Server to SNMP
management software. You can download these MIB files from the VMware Web site.
Table 5-1 lists the MIB files provided by VMware and describes the information that each file provides.
