  用zabbix监控mysql(源码安装)安装位置在/usr/local/zabbix/
 
  监控端(server):
 
  在被监控端主机上关联该模板Template App MySQL
 
  中文:组态->主机->名称一栏点击进去->模板,点击链接新模板->添加->Template App MySQL->存档
 
  英文:Configuration->Hosts->Name->Templates,Link new templates->Add->Template App MySQL->Save
 
  使用zabbix监控mysql详细解析
 
  2. 被监控端(agent):
 
  1)在源码包../zabbix-2.2.1/conf/zabbix_agentd/ 拷贝模板
 
  cp zabbix-2.2.1/conf/zabbix_agentd/userparameter_mysql.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d/
 
  2)授予监控mysql信息的用户权限
 
  mysql> grant usage on *.* to zabbix@'localhost' identified by 'zabbix';
 
  3)修改my.cnf
 
  [mysqladmin]
 
  host=localhost
 
  user=zabbix
 
  password=zabbix
 
  [mysql]
 
  host=localhost
 
  user=zabbix
 
  password=zabbix
 
  4)修改
 
  vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/userparameter_mysql.conf
 
  UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -uzabbix -pzabbix -hlocalhost -N | awk '{print $$2}'
 
  UserParameter=mysql.size[*],echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all"
 
   || ! "$1" ]] || echo " where table_schema='$1'")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name='$2'");" | HOME=/var/lib/zabbix mysql -uzabbix -pzabbix -hlocalhost -N
 
  UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin -uzabbix -pzabbix -hlocalhost ping | grep -c alive
 
  UserParameter=mysql.version,mysql -uzabbix -pzabbix -hlocalhost -V
 
  5)
 
  # /etc/init.d/mysqld restart
 
  # /etc/init.d/zabbix_agentd restart
 
  6)在server上的查看图像数据
 
       Monitoring->Graphs->MySQL operations
 
  nagios监控主从
 
  ls /usr/local/nagios/etc/objects/commands.cfg
 
  # vim /usr/local/nagios/etc/objects/commands.cfg
 
  define command  {
 
           command_name    check_mysql_slave
 
           command_line  $USER1$/check_mysql -H $HOSTADDRESS$ -S -uzabbix -pzabbix
 
    }
 
  修改被监控端的配置文件
 
  # vim zabbix_agent.cfg
 
  define service{
 
          use                             local-service
 
          host_name                       zabbix_agent
 
          service_description             MYSQL_SLAVE
 
          check_command                   check_mysql_slave                     
 
  }
 
  /etc/init.d/nagios restart
