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)
 
:wq
 
# 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
 
:wq
 
# killall nrpe
 
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
 
# vi /usr/local/nagios/etc/objects/ming.cfg

define service{
          use              generic-service
          host_name        ming
          service_description HA
          check_command      check_nrpe!check_haproxy
}
 
:wq
 
 
# service nagios restart
