nagios監控haproxy（藉助腳本）

修改後的腳本如下（需添加指示燈的狀態）

# 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 指的是狀態燈綠燈，2指的是紅燈，黃燈不用     並且宕了之後再次check時就能自動重啓

# 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        (註釋掉)

nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/haproxy.sh    (多個腳本的話設置多行)
 
:wq
 
# su - nagios -c 'sudo /usr/local/nagios/libexec/haproxy.sh'    (看看執行是否成功)
 
# vi /usr/local/nagios/etc/nrpe.cfg
 
command[check_haproxy]=/usr/bin/sudo /usr/local/nagios/libexec/haproxy.sh
 
:wq
 
# killall nrpe
 
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
 
# vi /usr/local/nagios/etc/objects/ming.cfg
