We use Solarwinds Orion for this stuff. We have some alerts for some switch Ports configured. You can get a trial version at www.solarwinds.com 2011/3/12 Wil Schultz <wschultz@bsdboy.com>

I use this Nagios plugin for up/down status alerts, it has some support for interface bandwidth (and errors/discards) monitoring. It's just a perl script so you could easily modify it to suit your needs.

Sorry about that. (Too jittery this morning) I was to confirm that Cacti (Lookup CactiEZ for quick testing) + Threshold plugin has been working for well over 6 months in our test lab. The site has over 18,000 thresholds and that on a single clunker, un-optimized it takes about 1m to process. We mainly placed threshold on Environment reading, Traffic High/Low, Discards and other Errors on each ports. You should check Cacti licensing, I think it is still GPL. ----- Alain Hebert ahebert@pubnix.net PubNIX Inc. 50 boul. St-Charles P.O.
