使用Zabbix + MPM全面监控MySQL

Zabbix和MPM监控MySQL

• 环境说明

  A: 192.168.1.190, 系统CentOS 6.3,部署Zabbix Server
  B: 192.168.1.191, 系统CentOS 6.3,部署Zabbix Agent, MySQL 5.5.29 (MySQL Slave)

• MPM/Zabbix监控结构及部署步骤

  MPM/Zabbix监控结构:

  

  MPM/Zabbix监控MySQL的大概步骤如下:

  • 安装部署Zabbix
  • 下载安装MPM(Performance Monitor for MySQL)及其依赖的Perl模块
  • 导入MPM模板
  • 创建host group(可选)
  • 创建host (即MPM agent配置中的database)
    值得注意的是:Hostname必须与MPM agent配置中的所使用的一致
  • 将选择的模板关联到创建的host
  • 配置MPM agent
  • 将MPM agent”挂钩”到Zabbix agent
    # cat /path_to_zabbix_agent_conf/zabbix_agentd.conf
    UserParameter=FromDual.MySQL.check,/path_to_mpm_agent/FromDualMySQLagent.pl \
    /path_to_mpm_agent_conf/FromDualMySQLagent
  • 重启Zabbix agent

• 安装部署Zabbix

  请参考《安装部署分布式监控系统Zabbix 2.06》 http://www.linuxidc.com/Linux/2013-07/86942.htm

• 注意：以下操作都是在被监控端执行的。

• MPM下载及其依赖安装 

  MPM(PERFORMANCE MONITOR FOR MYSQL)依赖的相关Perl模块安装:
   yum install perl-File-Which perl-libwww-perl perl-Digest-SHA1 perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay
  下载MPM并解压:
  wget -c http://www.shinguz.ch/download/mysql_performance_monitor-latest.tar.gz
  tar zxvf mysql_performance_monitor-latest.tar.gz
  

• Zabbix Web UI导入MPM模板

  MPM模板:
  tar zxvf mysql_performance_monitor_templates-0.9.1.tar.gz
  cd mysql_performance_monitor_templates-0.9.1/xml

         注意：导入模板前可以先将这些模板保存到windows下，然后在zabbix web界面进行导入。

• 在Zabbix Web UI导入监控所需的模板(“Configuration”->”Templates”->”Import”):
  Template_FromDual.MySQL.mpm.xml (监控mpm agent本身,这个必须导入)
  Template_FromDual.MySQL.server.xml (监控Linux系统跟数据库使用相关的附加项)
  Template_FromDual.MySQL.process.xml (监控各种Linux进程[比如:mysqld,ndbd])
  Template_FromDual.MySQL.mysql.xml (监控MySQL常用状态变量)
  Template_FromDual.MySQL.innodb.xml (监控InnoDB存储引擎状态变量)
  Template_FromDual.MySQL.myisam.xml (监控MyISAM存储引擎状态变量)
  Template_FromDual.MySQL.master.xml (监控MySQL主从复制的Master状态)
  Template_FromDual.MySQL.slave.xml (监控MySQL主从复制的Slave状态)
  MPM其它用途的模板:
  Template_FromDual.MySQL.ndb.xml (监控MySQL Cluster)
  Template_FromDual.MySQL.galera.xml (监控MySQL Galera Cluster)
  Template_FromDual.MySQL.pbxt.xml (监控PBXT存储引擎状态变量)
  Template_FromDual.MySQL.aria.xml (监控Aria存储引擎的状态变量)
  Template_FromDual.MySQL.drbd.xml (监控DRBD设备状态信息)
  

• 安装MPM和配置MPM Agent的Zabbix Keys

  安装MPM:

  tar zxvf mysql_performance_monitor_agent-0.9.1.tar.gz
  mv mysql_performance_monitor_agent-0.9.1 /usr/local/mysql_performance_monitor-agent
  

  修改FromDualMySQLagent.pl中的zabbix_sender的路径:

  cd /usr/local/mysql_performance_monitor-agent/
  sed -i 's|/usr/local/bin|/usr/local/zabbix/bin/|g' FromDualMySQLagent.pl
  

  将MPM Agent的Keys配置添加到Zabbix Agentd配置文件目录中:

  cd /usr/local/zabbix/etc/zabbix_agentd.conf.d
  vi FromDual_MySQL_monitoring.conf
  # cat FromDual_MySQL_monitoring.conf 
  

  UserParameter=FromDual.MySQL.check,/usr/local/mysql_performance_monitor-agent/FromDualMySQLagent.pl /usr/local/mysql_performance_monitor-agent/etc/FromDualMySQLagent.conf

• MPM Agent配置

  创建MySQL监控用户mpm:

  mysql> create user 'mpm'@'127.0.0.1' identified by '123456';
  mysql> grant process, replication client on *.* to 'mpm'@'127.0.0.1';
  mysql> flush privileges;
  

  配置MPM Agent:

  cd /usr/local/mysql_performance_monitor-agent/etc
  cp FromDualMySQLagent.conf.template FromDualMySQLagent.conf
  mkdir -p /var/log/zabbix
  mkdir -p /var/log/zabbix/cache
  touch /var/log/zabbix/FromDualMySQLagent.log
  chown -R zabbix:zabbix /var/log/zabbix
  chmod o+r /var/run/mysqld/mysqld.pid #这里要根据自己实际情况进行修改
  vi FromDualMySQLagent.conf
  # cat FromDualMySQLagent.conf
  

  [default]
  
  # Type of section:
  # mysqld for a normal MySQL database
  # ndbd   for a MySQL cluster
  Type         = mysqld
  
  # Debug levels are:
  # 1 is logging only errors
  # 2 is logging errors and warnings (this is the default)
  # 3 logs some informations messages as well
  # 4 logs everything (for debugging purposes only)
  
  Debug         = 2
  LogFile       = /var/log/zabbix/FromDualMySQLagent.log
  # Directory where the Cache files should be written to:
  CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache
  
  # If you agent is not located in the same time zone as your server
  # TimeShift = +0.0
  
  # Information for MySQL connections: 下面的这几项需要修改
  Username     = mpm
  Password     = 123456
  MysqlHost    = 127.0.0.1
  MysqlPort    = 3306
  
  # Zabbix Server IP address 需要修改
  ZabbixServer = 192.168.1.190
  
  # If section is disabled
  Disabled     = false
  
  # Possible modules for databases are:
  # process mysql myisam aria innodb pbxt ndb master slave drbd galera memcache
  # Possible modules for servers are:
  # mpm server
  # Usual modules are
  Modules      = process mysql myisam innodb
  
  # Special parameter which is used for module ndb and process
  ClusterLog   = /var/lib/mysql-cluster/ndb_1_cluster.log
  # MySQL Pid file, need read permission for zabbix user
  PidFile      = /var/run/mysqld/mysqld.pid #这里也需要修改
  
  [db_server]
  
  Type         = mysqld
  Modules      = mpm server
  
  
  # All MySQL databases here
  # Try to avoid section names with spaces!
  
  [192.168.1.191_MySQL_5.5.29]   # This MUST match Hostname in Zabbix! 注意：该行及以下的几行需要取消注释
  Type         = mysqld
  MysqlPort    = 3306
  Modules      = process mysql myisam innodb slave
  PidFile      = /var/run/mysqld/mysqld.pid
  Debug        = 1
  

  注:这里监控的MySQL Server是MySQL主从复制的中的Slave机器.

• 开始监控MySQL
  Zabbix Web UI创建host (192.168.1.191_MySQL_5.5.29):

• 

  

  重启Zabbix Agentd:

  # /etc/init.d/zabbix_agentd restart
  

  Zabbix Web UI的”Monitoring”->”Latest data”可以查看监控情况:
