I'm attempting to monitor the bandwidth usage on our network. I've come across two products that seem to fulfil our needs. MRTG and nTop, however I'm unsure which to use.
My work is a small company of about 10 people. We have a standard 4 port ADSL2 router that connects to a (Netgear) gigabit switch that gets used by our staff. DHCP is on the router itself, we have a designated fileserver/NAS that is running (Currently) Linux Ubuntu 8.04 LTS.
If I wanted to monitor usage of traffic, can I install either on the Linux box (others are Windows) and use SNMP to monitor the traffic or do I need to setup another box which will be our DHCP and have that monitoring the usage? How do they anaylse traffic otherwise?
