Not quite sure what you're asking... whether the link is degrading in what
>From the way you have worded your question, I would guess you're actually
asking about utilisation and monitoring this proactively.
MRTG should be good for this, if you set the thresholds to alert you when
utilisation goes over a certain parameter defined by yourself.
With regard to latency or the such to identify if a link if going bad you
could setup various probes on the routers; gives 'Cisco IP SLA' a bash in
Google and it should return some useful docs on configuring this.
