SNMP and vSphere
Simple Network Management Protocol (SNMP) allows management programs to monitor and control a variety
of networked devices.
Managed systems run SNMP agents, which can provide information to a management program in at least one
of the following ways:
n
In response to a
GET
operation, which is a specific request for information from the management system.
n
By sending a trap, which is an alert sent by the SNMP agent to notify the management system of a particular
event or condition.
Management Information Base (MIB) files define the information that can be provided by managed devices.
The MIB files contain object identifiers (OIDs) and variables arranged in a hierarchy.
vCenter Server and ESX/ESXi have SNMP agents. The agent provided with each product has differing
capabilities.
Using SNMP Traps with vCenter Server
The SNMP agent included with vCenter Server can be used to send traps when the vCenter Server system is
started and when an alarm is triggered on vCenter Server. The vCenter Server SNMP agent functions only as
a trap emitter, and does not support other SNMP operations, such as
GET
.
The traps sent by vCenter Server are typically sent to other management programs. You must configure your
management server to interpret the SNMP traps sent by vCenter Server.
To use the vCenter Server SNMP traps, configure the SNMP settings on vCenter Server and configure your
management client software to accept the traps from vCenter Server.
The traps sent by vCenter Server are defined in
VMWARE-VC-EVENT-MIB.mib
. See “VMWARE-VC-EVENT-
MIB,” on page 62.
