Linux下针对服务器网卡流量和磁盘的监控脚本

1）实时监控网卡流量的通用脚本：

[root@ceph-node1 ~]# cat /root/net_monit.sh
#!/bin/bash
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin;
export PATH
function traffic_monitor {

  OS_NAME=$(sed -n '1p' /etc/issue)

  eth=$1

  if [ ! -d /sys/class/net/$eth ];then
      echo -e "Network-Interface Not Found"
      echo -e "You system have network-interface:\n`ls /sys/class/net`"
      exit 5
  fi
  while [ "1" ]
  do

    STATUS="fine"

    RXpre=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $2}')
    TXpre=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $10}')

    sleep 1
    RXnext=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $2}')
    TXnext=$(cat /proc/net/dev | grep $eth | tr : " " | awk '{print $10}')
    clear

    RX=$((${RXnext}-${RXpre}))
    TX=$((${TXnext}-${TXpre}))

    if [[ $RX -lt 1024 ]];then
      RX="${RX}B/s"
    elif [[ $RX -gt 1048576 ]];then
      RX=$(echo $RX | awk '{print $1/1048576 "MB/s"}')
      $STATUS="busy"
    else
      RX=$(echo $RX | awk '{print $1/1024 "KB/s"}')
    fi

      elif [[ $TX -gt 1048576 ]];then
      TX=$(echo $TX | awk '{print $1/1048576 "MB/s"}')
    else

    fi
