Alarm definition on NIC Speed

Hi All,

Is there a way to setup an alarm definition so we can be notified if the NIC speed is 100 Mbps/s instead of 1000 Mbps/s on vSphere ESXi host ?

We have vSphere Server 5.5 and vSphere ESXi 5.1 hosts connected to the vSphere Server.

I know it is possible to do it on the switch side, but we would prefer doing it on the server side, if possible.

Thank you,

Dominic
