nagios监控haproxy（借助脚本）

nagios监控haproxy（借助脚本）

修改后的脚本如下（需添加指示灯的状态）

# vi haproxy.sh

#!/bin/bash

Port=`netstat -ntpl | grep haproxy | awk -F[:" "]+ '{print $5}'`

if [ $Port == "1080" ];then

echo "OK - haproxy is running" 

exit 0

else

echo "CRITICAL - haproxy is down" 

/usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/haproxy.cfg

exit 2

fi

:wq

注：0 指的是状态灯绿灯，2指的是红灯，黄灯不用     并且宕了之后再次check时就能自动重启

# cp haproxy.sh  /usr/local/nagios/libexec

# chmod +x /usr/local/nagios/libexec/haproxy.sh

# mount /dev/cdrom /media/cdrom

# rpm -ivh sudo-1.6.9pl7-3.el5.i386.rpm

# visudo

#Defaults    requiretty        (注释掉)

nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/haproxy.sh    (多个脚本的话设置多行)

# su - nagios -c 'sudo /usr/local/nagios/libexec/haproxy.sh'    (看看执行是否成功)

# vi /usr/local/nagios/etc/nrpe.cfg

command[check_haproxy]=/usr/bin/sudo /usr/local/nagios/libexec/haproxy.sh

# killall nrpe

# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
