What counters are used to measure network traffic?

The values of Network Interface counters measure the number of bytes sent or received over a TCP/IP connection. No pre-defined values have been set for these counters. A sudden increase in the network traffic indicates an external attack. The counters used to measure the network traffic are as follows:

  • Network Interface: Bytes Received/sec: This counter shows the rate at which bytes are received by a network. A sudden and unexpected increase in the value of this counter indicates an external attack on the network.
  • Network Interface: Bytes Sent/sec: This counter shows the rate at which the bytes are sent through the network. A sudden increase in the value of this counter indicates that a large volume of data is being accessed. It also indicates an external attack on the network.
  • Network Interface: Bytes/sec: This counter measures the rate at which the bytes are sent through or received by a network. A sudden increase in the value of this counter indicates an external attack on the network.
  • Network Interface: Output Queue Length: This counter is maintained by TCP/IP. It is used to measure the number of output packets in a queue. An increase in the value of this counter indicates that the server is experiencing periods of unresponsiveness. Its value can also increase if the server contains faulty network hardware.
