nagios監控mysql主從

nagios監控mysql的主從，我這裏介紹兩種方法，一種是用nagios自帶監控mysql 的插件實現，另外一種是本身寫腳本，下面是兩種方法的具體實現過程：

1、nagios自帶監控mysql的插件實現

一、編輯/usr/local/nagios/etc/commands.cfg，添加監控mysql主從的字段：

define command{
        command_name   check_mysql_slave
        command_line   $USER1$/check_mysql -H $HOSTADDRESS$ -P13267 -S -uroot -p123456 -s /data/mysql/nagios/logs/mysql.sock 
        }

PS：-u指定用戶，-P指定端口，-p指定密碼，-s指定sock文件路徑，-S監控主從

二、編輯/usr/local/nagios/etc/objects/cfg/navyserver.cfg ，添加監控mysql主從項目：

define service{
        use             generic-service
        host_name       navy
        service_description     check_mysql_slave1
        check_command           check_mysql_slave
        }

三、重啓nagios就OK了

/etc/init.d/nagios restart

2、腳本監控

一、撰寫監控腳本

vi /usr/local/nagios/libexec/check_mysql_slave
#!/bin/sh 
declare -a    slave_is 
slave_is=($(cd /data/mysql/nagios; /data/mysql/nagios/bin/mysql --sock=logs/mysql.sock  -unagios -p123456  -e "show slave status \G"|grep Running |awk '{print $2}')) 
if [ "${slave_is[0]}" = "Yes" -a "${slave_is[1]}" = "Yes" ] 
     then 
     echo "OK -slave is running" 
     exit 0 
else 
     echo "Critical -slave is error" 
     exit 2 
fi

二、在/usr/local/nagios/etc/nrpe.cfg中添加監控mysql主從的命令

command[check_mysql_slave]=/usr/local/nagios/libexec/check_mysql_slave

三、編輯/usr/local/nagios/etc/objects/cfg/navyserver.cfg ，添加監控mysql主從項目：

define service{
        use             generic-service
        host_name       navy
        service_description     check_mysql_slave
        check_command           check_nrpe!check_mysql_slave
        }

四、重啓nagios就OK了

/etc/init.d/nagios restart
