Your network needs dedicated always running software such as cacti or one
of the others already mentioned.

FusionInventory.org is a newcomer to snmp mapping (it already has a kitchen
sink) but other parts of the project have been for about 12 years.   I was
testing out a much older version of their network mapping component when i
found out i had YAHDDF (Yet Another HardDiskDrive Failure) on the server.
FusionInventory does run as a service all-the-time, but you would probably
want something dedicated to just networking.

The stuff i mostly have used came on a LiveCD (probably BackTrack /
RemoteExploit) and generated graphs but the name escapes me now, anybody
remember?  This type of software is good for one off type stuff.
i had tried out netmap and jnetmap before on Ubuntu but it isn't in a
repository for the CentOS machine i am using now.   There is something else
called netmapr.

You might want to install iperf / jperf from a repository as well to
manually verify speed between nodes, but cacti will do that automatically.
