Prerequisites
To complete this task, you must download the VMware MIB files from the VMware website.
Procedure
1 In your management software, specify the vCenter Server or ESX/ESXi system as an SNMP-based
managed device.
2 Set up appropriate community names in the management software.
These must correspond to the communities set for the SNMP agent on the vCenter Server system or
ESX/ESXi host.
3 (Optional) If you configured the SNMP agent to send traps to a port on the management system other
than the default UDP port 162, configure the management client software to listen on the port you
configured.
4 Load the VMware MIBs into the management software so you can view the symbolic names for the vCenter
Server or ESX/ESXi variables.
To prevent lookup errors, load the MIB files in the following order:
a
VMWARE-ROOT-MIB.mib
b
VMWARE-TC-MIB.mib
c
VMWARE-PRODUCTS-MIB.mib
d
VMWARE-SYSTEM-MIB.mib
e
VMWARE-ENV-MIB.mib
f
VMWARE-RESOURCES-MIB.mib
g
VMWARE-VMINFO-MIB.mib
h
VMWARE-OBSOLETE-MIB.mib
(for use with versions of ESX/ESXi prior to 4.0)
i
VMWARE-AGENTCAP-MIB.mib
j
VMWARE-VC-EVENT-MIB.mib
The management software can now receive and interpret traps from vCenter Server or ESX/ESXi systems.
SNMP Diagnostics
Use SNMP tools to diagnose configuration problems.
You can use the following tools to diagnose problems with SNMP configuration:
n
Type
vicfg-snmp.pl --server <hostname> --username <username> --password <password> --test
at the
vSphere command-line interface to prompt the embedded SNMP agent to send a test
warmStart
trap.
n
Type
vicfg-snmp.pl --server <hostname> --username <username> --password <password> --show
to
display the current configuration of the embedded SNMP agent.
n
The
SNMPv2-MIB.mib
file provides a number of counters to aid in debugging SNMP problems. See
“SNMPv2 Diagnostic Counters,” on page 65.
n
The
VMWARE-AGENTCAP-MIB.mib
file defines the capabilities of the VMware SNMP agents by product
version. Use this file to determine if the SNMP functionality that you want to use is supported.
