Network Monitoring

[mraisley]

I work for an ISP with about 4,000 dial up and around 200 DSL. We also have T1, Frame-relay and some ISDN accounts as well. We are looking to purchase a network management software tool to help monitor bandwidth usage and things of such. Any recommendations?

Thank you for all replies

Also check out Lucent VitalNet (a.k.a VitalSuite)

We use it on our 80+ router Frame Relay WAN, and it works great. Consider it like MRTG on super-steroids.

Give Prtg a try. Sort like MRTG, but runs under windows, easy to setup. Not free, but has a freeware 5 device version.

I use a freeware utility called NMIS. It is written in perl and uses snmp for polling and collection. In my opinion it is awesome. I run it on a linux server although it can be ported to windows. It takes a little time and effort to setup but is well worth it.
