ntop bandwidth monitor
ntop is a very simple yet powerful bandwidth monitor which outputs various statistics counters in RRD.
RRD – Round Robin Database – is a very handy framework for saving server performance counters in a ring buffer.
We can say that if we would like to graph network performance, ntop does most of the hard work for us and all we have left to do is to graph the counters.
Among the counters ntop exposes there are:
- Total bytes per interface
- Total HTTP, DHCP, DNS, NetBIOS bytes per interface
- Interface throughput
- IGMP, ARP statistics
And speaking of graphing, we have Monitis, which can graph any counter we can think of. I have an idea – lets graph ntop data with Monitis!
