Probe for Network Monitoring

I was wondering if anyone has created and willing to share a probe to send an alert if a port on a Cisco router or switch exceeds a certain amount of bandwidth? Right now I can monitor the interfaces and see the statistics off the links that I have created but I cannot and an auto generated alert if they reach or exceed a certain threshold.

Yes there are probes built like you want but you will need to search for posts from gsandul for those also each one will need to be hard coded to the interface you are interested in.
