From: geoar75 on 23 Apr 2010 01:56 I mentioned MRTG, because I'm already using it on some of our routers to check the speed utilization. It would be great if I set it up to include the BRI interfaces as well. Though it will take lots of time and research to setup all those MIBs and OIDs, it would be very interesting. Alerting is not on my plans yet, that's why MRTG would be one of the best solutions. Thanks again! Giorgos

MRTG can for sure do the job but I suspect that it is no longer in development (years ago now) and that you might be better investing your time in something else. I have not used it but Cacti seems to be recommended.
