Good point. This method really does not monitor the link speed, instead it alerts on the bandwidth being utilized on the port.
I would imagine link speed can be polled using SNMP. Using OnCommand Unified Manager I'm able to generate a report on link speed, but it seems to only be reporting for our clustered Data ONTAP systems.
Would it be sufficient to get a report on it, or is an alert necessary?
Re: is there a simple alert that can be defined in DFM / Operations Manager to send an alert if the Ethernet port speed is ever lower than 1000mbps?
