查看linux server網絡流量的shell腳本
上傳下載大量文件的時候,可以使用這個腳本來實現監控!
#!/bin/sh ###統計5s內的平均流量,以Mb爲單位 if [ "$1" = "" ];then echo -e "\n use interface_name after the script,like \"$0 eth0\"...\n" exit -1 fi echo -e "\n start monitoring the $1,press \"ctrl+c\" to stop" echo ---------------------------------------------------------- #ls /etc/sysconfig/network-scripts/|grep ifcfg|cut -d "-" -f 2 while true do RX_bytes=`cat /proc/net/dev|grep "$1"|awk '{print $1}'|cut -d ":" -f 2` TX_bytes=`cat /proc/net/dev|grep "$1"|awk '{print $9}'` sleep 5 RX_bytes_later=`cat /proc/net/dev|grep "$1"|awk '{print $1}'|cut -d ":" -f 2` TX_bytes_later=`cat /proc/net/dev|grep "$1"|awk '{print $9}'` ###Mb=B*8/1024/1024 speed_RX=`echo "scale=2;($RX_bytes_later - $RX_bytes)*8/1024/1024/10"|bc` speed_TX=`echo "scale=2;($TX_bytes_later - $TX_bytes)*8/1024/1024/10"|bc` printf "%-3s %-3.1f %-10s %-4s %-3.1f %-4s\n" IN: $speed_RX Mb/s OUT: $speed_TX Mb/s done
使用效果如下圖
