Linux常用的服务器监控shell脚本

下面是我常用的几个主机监控的脚本，大家可以根据自己的情况在进行修改，希望能给大家一点帮助。

　

1、查看主机网卡流量

 

#!/bin/bash
#network

#Mike.Xu

while : ; do

time='date +%m"-"%d" "%k":"%M'

day='date +%m"-"%d'

rx_before='ifconfig eth0|sed -n "8"p|awk '{print $2}'|cut -c7-'

tx_before='ifconfig eth0|sed -n "8"p|awk '{print $6}'|cut -c7-'

sleep 2

rx_after='ifconfig eth0|sed -n "8"p|awk '{print $2}'|cut -c7-'

tx_after='ifconfig eth0|sed -n "8"p|awk '{print $6}'|cut -c7-'

rx_result=$[(rx_after-rx_before)/256]

tx_result=$[(tx_after-tx_before)/256]

echo "$time Now_In_Speed: "$rx_result"kbps Now_OUt_Speed: "$tx_result"kbps"

sleep 2

done

 

 

 

2、系统状况监控

 
#!/bin/sh

#systemstat.sh

#Mike.Xu

IP=192.168.1.227

top -n 2| grep "Cpu" >>./temp/cpu.txt

free -m | grep "Mem" >> ./temp/mem.txt

df -k | grep "sda1" >> ./temp/drive_sda1.txt

#df -k | grep sda2 >> ./temp/drive_sda2.txt

df -k | grep "/mnt/storage_0" >> ./temp/mnt_storage_0.txt

df -k | grep "/mnt/storage_pic" >> ./temp/mnt_storage_pic.txt

time=`date +%m"."%d" "%k":"%M`

connect=`netstat -na | grep "219.238.148.30:80" | wc -l`

echo "$time  $connect" >> ./temp/connect_count.txt
