Collecting Network Statistics With netstat

Collecting Network Statistics With netstat

The netstat tool displays various network-related data structures that are useful for monitoring and troubleshooting a network. Detailed statistics about network collisions can be captured with the netstat tool. Collision rates above 5% could indicate a problem with the network. The problem could be physical (bad tap, transceiver, loose terminator, and so on) or there might be too much traffic on the network.

This example illustrates the statistics you might see on a station using netstat. See the netstat(1) reference page for details about the many netstat options:

netstat -i

Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll

enp0 1500 b1-channels thumper 498690 937 1066135 3 4858

lo0 32880 loopback localhost 1678915 0 1678915 0 0

The collision rate is approximately 0.45%, well within the acceptable range.
