I'm currently trying to write a script to confiugre SNMP settings on multiple ESX hosts. I'm able to wtire the code that configures the SNMP but I need help with 2 things.
Firstly I'm trying to create an array to hold all the ESX host names. I know that I could use "$hosts=get-vmhost | name" but a few of the hosts all ready have SNMP configured correctly. Can you create an array and manually give it a list of host names?
Secondly I will need to restart the snmp service after its configured. I know how to do this in the ESX conolse but am not sure how to script it in powershell.
Thanks in advance guys.
Btw, you can't restart the SNMP service on ESXi host but you can enable/disable it with PowerCLI.
Connect to the ESXi server (not the vCenter) and do
Get-VMHostSnmp | Set-VMHostSnmp -Enabled:$true -AddTarget -TargetHost "myHost" -TargetCommunity "public"
Get-VMHostSnmp | Set-VMHostSnmp -Enabled:$false
In fact why do you need to stop/start the SNMP service ?
You can change target hosts, communities ... on the fly.
Update: just did a bit of recerse-engineering on the vicfg-snmp.pl file.
And in fact what is called Stop and Start in that script is the -Enable:$true and -Enable:$false on the Set-VMHostSnmp cmdlet.
So, you can do exactly the same thing with PowerCLI.
