4. Command line Parameters

The following is the Nethogs command line parameter, with '-d ' to add the refresh frequency parameter, ' device name ' is used to detect the bandwidth of a given or some device (default is eth0). For example: To set the refresh rate for 5 seconds, type the following command:

# nethogs-d 5

If only the network bandwidth used to monitor the device (eth0) can use the following command:

# nethogs Eth0

If you want to monitor both the eth0 and ETH1 interfaces, use the following command:

# nethogs Eth0 eth1

Additional parameters and usage:

-d:delay for Refresh Rate,default is 1.

-h:display available commands usage.

-p:sniff in promiscious mode (not recommended).

-t:tracemode.

-b:bughunt mode-implies TraceMode.

-v:prints Version Info.
