文档介绍：1、查看主机网卡流量
#!/bin/bash
#network
#fei
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
#
#
IP=
top -n 2| grep "Cpu" >>./temp/
free -m | grep "Mem" >> ./temp/
df -k | grep "sda1" >> ./temp/
#df -k | grep sda2 >> ./temp/
df -k | grep "/mnt/storage_0" >> ./temp/
df -k | grep "/mnt/storage_pic" >> ./temp/
time=`date +%m"."%d" "%k":"%M`
connect=`netstat -na | grep ":80" | wc -l`
echo "$time $connect" >> ./temp/
3、监控主机的磁盘空间,当使用空间超过90%就通过发mail来发警告
#!/bin/bash
#monitor available disk space
SPACE='df | sed -n '/ \ / $ / p' | gawk '{print $5}' | sed 's/%//'
if [ $SPACE -ge 90 ]
then
fty89@
fi
4、监控CPU和内存的使用情况
#!/bin/bash
#script to capture system statistics
OUTFILE=/home/xu/
DATE='date +%m/%d/%Y'
TIME='date +%k:%m:%s'
TIMEOUT='upti
