How-To: Setup SNMP on ESX 3.5 Servers

To monitor your ESX 3.5 server by using SNMP, we need to enable SNMP on ESX before adding it to your monitoring software. This How-To will show you the steps involved.


Log Into ESX Server


Log into your ESX Server either through SSH or through the console of the server.

Use Nano to Edit Snmpd.conf


Use Nano (which is a notepad like text editor) to edit the file /etc/snmp/snmpd.conf file by using the command:
nano /etc/snmp/snmpd.conf

Add SNMP Community to Config File


Use the arrow keys to go down to the section “rocommunity public”. Replace “public” with your community string for your environment (1). Then use “Ctrl+X” to exit out of Nano. You’ll be asked if you would like to save. Type in “y” for yes and hit enter. Press enter again when confirming the filename to save as.

Enable SNMP to Start Automatically After a Reboot


Since SNMP is not started by default, you’ll need to type in this command to ensure it will be started after a reboot of the ESX server. The command is:
chkconfig snmpd on

Enable SNMP Through the ESX Firewall


We’ll need to allow SNMP traffic through the built-in ESX firewall. To do this, type in the following command:
esxcfg-firewall -e snmpd

Start the SNMP Service


Now we’re ready to start the SNMP service. Type in:
service snmpd start

Ready for Monitoring

At this point, SNMP is enabled on your ESX 3.5 server and you can monitor it using your SNMP monitoring software! Happy monitoring!

  1. If you need information regarding the ESX MIBs, you can find it in the VI3 Admin Guide:

    Click to access vi3_35_25_admin_guide.pdf

    If you simply need to enable SNMP traps to your monitoring solution (used in conjunction with Virtual Center alert notification), you can find this in the VI Client under the menu: Administration > VirtualCenter Management Server Configuration
