nagios 监控slave（check_mysql_health插件）

http://labs.consol.de/wp-content/uploads/2011/08/check_mysql_health-2.1.7.tar.gz

# mount /dev/cdrom /media/cdrom
# rpm -ivh /media/cdrom/Server/perl-DBI-1.52-2.el5.i386.rpm
# rpm -ivh /media/cdrom/Server/perl-DBD-MsSQL-3.0007-2.el5.i386.rpm --nodeps

# tar zxf check_mysql_health-2.1.7.tar.gz
# cd check_mysql_health-2.1.7
# ./configure
# make && make install

# mysql -u root -p123456
> grant all on *.* to ming@'192.168.1.10' identified by '123456';
> quit

下面要借助于nrpe（nrpe安装步骤略）

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

command[slave_io_running]=/usr/local/nagios/libexec/check_mysql_health --hostname 192.168.1.10 --port 3306 --username ming --password 123456 --mode slave-io-running --critical No

command[slave_io_running]=/usr/local/nagios/libexec/check_mysql_health --hostname 192.168.1.10 --port 3306 --username ming --password 123456 --mode slave-sql-running --critical No

:wq

重启nrpe：

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

# vi /usr/local/nagios/etc/objects/ming.cfg                     (ming.cfg为监控主机的文件，自建的)

define service{
        use                             local-service         ; Name of service template to use
        host_name                       myhostname
        service_description             slave-io-running
        check_command                   check_nrpe!slave_io_running
        }

define service{
        use                             local-service         ; Name of service template to use
        host_name                       myhostname
        service_description             slave-sql-running
        check_command                   check_nrpe!slave_sql_running
        }

:wq

重启nagios

# service nagios restart
