Here are the commands I have used for the vCenter SNMP configuration. Note: make sure you have access to the root account to perform the login.
# Step 1: Start an SSH connection with the vCenter Server (use Putty or something equivalent).
# Step 2: Login as the root user
# Step 3: After a successful login you should be in the appliance Shell.
# Step 4: View the current configuration for SNMP
snmp.get
# Step 5: Configure the SNMP Community (in this example I use MySnmpCommunity)
snmp.set --communities MySnmpCommunity
# Step 6: Allow a device to access the SNMP agent (192.168.10.10 = monitoring server)
snmp.set --targets 192.168.10.10@161/MySnmpCommunity,172.0.0.1@161/MySnmpCommunity,localhost@161/MySnmpCommunity
# Step 7: Enable the SNMP Agent
snmp.enable
# Step 7: Verify the SNMP Settings configured
snmp.get
# Step 8: Test the working (in my case it never works... not sure why? Has something to do with my access restrictions?)
snmp.test
# Step 9: Perform a test from the monitoring server (in my case a Linux machine with snmpwalk)
snmpwalk -v2c -c MySnmpCommunity %hostname-vcenter%#
"/vmfs/volumes/remote_datastore/backups/folder_with_VM1/;/vmfs/volumes/datastore1;4;VM1-test" "/vmfs/volumes/remote_datastore/backups/folder_with_VM2/;/vmfs/volumes/datastore1;4;VM2-test"where each line specifies path to backup (the folder with vmdk file), destination on a host where the machine would run, disk format type (4 for eagerzeroedthick) and a new name.
# ./ghettoVCB-restore.sh -c vms_to_restore
The script will clone and register the VM on the destination host.
You can power it up from the client later, and client will ask you
whether you moved it (uuid and MAC will stay the same) or copied (uuids
and MAC would be regenerated and ruin MAC-bonded licences on your VM).

So here you go, a bit of PowerCLI to set your SNMP up on each of your hosts in vCenter.
# PowerCLI Script for adding syslogserver to hosts
# @mrlesmithjr
# EverythingShouldBeVirtual.com
# Change the following to match your environment
# vi_server is your vCenter
$vi_server = “vcenterservername”
$vcuser = "vcenterserverusername"
$vcpass = "vcenterserverpassword"
$communities = "public"
$syslocation = "Atlanta"
Connect-VIServer -Server $vi_server -User $vcuser -Password $vcpass
# Setup variable to use in script for all hosts in vCenter
$vmhosts = @(Get-VMHost)
# Configure syslog on each host in vCenter
foreach ($vmhost in $vmhosts) {
Write-Host ‘$vmhost = ‘ $vmhost
$esxcli = Get-EsxCli -VMHost $vmhost
$esxcli.system.snmp.set($null,$communities,"true",$null,$null,$null,$null,$null,$null,$null,$null,$null,$syslocation)
$esxcli.system.snmp.get()
}
Disconnect-VIServer * -Confirm:$false
So there you have it. You are good to go now. Have fun SNMP’ing away!
