写个简单的脚本。。
#!/bin/bash
#liboxaing
nmap 192.168.111.2 | grep 80 &> /dev/null
if [ $? -eq 0 ];
then
echo "YES"
exit 0
else
echo "NO"
exit 2
fi
再进一步应该可以
#!/bin/bash
IP=$1
nmap $1 | grep 80
if [ $? -eq 0 ];
then
echo "YES"
exit 0
else
echo "NO"
exit 2
fi
vim /usr/local/nagios/etc/objects/localhost.cfg
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
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@163.com
