Enable SNMP in vSphere ESX 6

Now that you are on or you have just started using VMware ESXi 6 and would like to do some monitoring via SNMP here is a way to enable this and set the community string in the process.

By default, remote clients are prevented from accessing services on host, unless configured to start automatically.

While you can simple set SNMP to start it does not set the community name and this is where we drop into the cli to do this.

First, make sure you have enabled SSH access to your ESXi node.
You can do that in Configuration > Security Profile > Services > SSH.

Connect to the ESXi 6 host terminal or via SSH and issue the following commands:

esxcli system snmp set –communities public
esxcli system snmp set –enable true

All done! Now add your host to your favourite SNMP powered monitoring tool (i.e. LibreNMS, Observium,..)
