In Linux, you can use the sar command to view network traffic.<\/p>\n

To use the sar command to view network traffic, follow these steps:<\/p>\n

    \n
  1. Ensure that the sar command is installed on your system. If it is not installed, you can use the following command to install it:<\/li>\n<\/ol>\n
    sudo apt-get install sysstat\r\n<\/code><\/pre>\n
      \n
    1. Open the terminal and enter the following command to check network traffic:<\/li>\n<\/ol>\n
      sar -n DEV\r\n<\/code><\/pre>\n
      This command will display statistical information for network devices, including amounts of data received and sent, and the number of errors.<\/p>\n
        \n
      1. If you only want to view the statistics of specific network devices, you can use the following command:<\/li>\n<\/ol>\n
        sar -n DEV -I <network_interface>\r\n<\/code><\/pre>\n
        Replace  with the name of the network device you want to view, such as eth0 or wlan0.<\/p>\n
          \n
        1. You can use the following command to view the historical records of network traffic.<\/li>\n<\/ol>\n
          sar -n DEV -s <start_time> -e <end_time>\r\n<\/code><\/pre>\n
          Replace  and  with the time range you want to view. The time format is HH:MM:SS, for example, 08:00:00 represents 8:00 AM.<\/p>\n
          These commands can assist you in using the sar command to view network traffic in Linux.<\/p>\n","protected":false},"excerpt":{"rendered":"
