that are assigned exclusively to virtual machines or shared between virtual machines

and the console operating system.

Configuring SNMP Security

The ESX Server SNMP package takes the simplest approach to SNMP security. It sets

up a single community with read-only access. This is denoted by the rocommunity

configuration parameter in snmpd.conf.

By design, SNMP is not a very secure protocol, and the community-based security

model is a retrofit to the protocol.

There are other enhancements to the SNMP security mechanism that allow an

administrator to set up a more elaborate permissions scheme. See the

snmpd.conf(5) man page for details. Note the exceptions mentioned in the

Configuration File Issues section above; other settings in the file may be made as

described by the man page.

Using SNMP with Guest Operating Systems

To use SNMP to monitor guest operating systems or applications running in virtual

machines, install the SNMP agents you would normally use for that purpose. No

special configuration is required.

Keep in mind that the virtual machine uses its own virtual hardware devices. You

should not install in the virtual machine agents intended to monitor hardware on the

physical computer.

VMware ESX Server SNMP Variables

The VMware enterprise tree is at

.iso.dod.org.internet.private.enterprises.vmware.

(.1.3.6.1.4.1.6876.) The tree consists of several groups; the variables in

each of the groups are shown in the tables below.

Note: All variables are read-only.

The data type field refers to the SNMP type described by the structure of

management information (SMI).
