netstat command

The netstat command is used to show network status.

Traditionally, it is used more for problem determination than for performance measurement. However, the netstat command can be used to determine the amount of traffic on the network to ascertain whether performance problems are due to network congestion.

The netstat command displays information regarding traffic on the configured network interfaces, such as the following:

• The address of any protocol control blocks associated with the sockets and the state of all sockets
• The number of packets received, transmitted, and dropped in the communications subsystem
• Cumulative statistics per interface
• Routes and their status
