Zabbix和MPM監控MySQL

Zabbix和MPM監控MySQL

• 請參考《安裝部署分佈式監控系統Zabbix 2.06》 http://www.linuxidc.com/Linux/2013-07/86942.htm

• 注意：如下操做都是在被監控端執行的。

• MPM下載及其依賴安裝 

  MPM(PERFORMANCE MONITOR FOR MYSQL)依賴的相關Perl模塊安裝:
   yum install perl-File-Which perl-libwww-perl perl-Digest-SHA1 perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay
  下載MPM並解壓:
  wget -c http://www.shinguz.ch/download/mysql_performance_monitor-latest.tar.gz
  tar zxvf mysql_performance_monitor-latest.tar.gz

• Zabbix Web UI導入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：導入模板前能夠先將這些模板保存到windows下，而後在zabbix web界面進行導入。

• 在Zabbix Web UI導入監控所需的模板(「Configuration」->」Templates」->」Import」):
  Template_FromDual.MySQL.mpm.xml (監控mpm agent自己,這個必須導入)
  Template_FromDual.MySQL.server.xml (監控Linux系統跟數據庫使用相關的附加項)
  Template_FromDual.MySQL.process.xml (監控各類Linux進程[好比:mysqld,ndbd])
  Template_FromDual.MySQL.mysql.xml (監控MySQL經常使用狀態變量)
  Template_FromDual.MySQL.innodb.xml (監控InnoDB存儲引擎狀態變量)
  Template_FromDual.MySQL.myisam.xml (監控MyISAM存儲引擎狀態變量)
  Template_FromDual.MySQL.master.xml (監控MySQL主從複製的Master狀態)
  Template_FromDual.MySQL.slave.xml (監控MySQL主從複製的Slave狀態)
  MPM其它用途的模板:
  Template_FromDual.MySQL.ndb.xml (監控MySQL Cluster)
  Template_FromDual.MySQL.galera.xml (監控MySQL Galera Cluster)
  Template_FromDual.MySQL.pbxt.xml (監控PBXT存儲引擎狀態變量)
  Template_FromDual.MySQL.aria.xml (監控Aria存儲引擎的狀態變量)
  Template_FromDual.MySQL.drbd.xml (監控DRBD設備狀態信息)

• 安裝MPM和配置MPM Agent的Zabbix Keys

  安裝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的路徑:

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

  將MPM Agent的Keys配置添加到Zabbix Agentd配置文件目錄中:

  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

  建立MySQL監控用戶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 #這裏要根據本身實際狀況進行修改
  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: 下面的這幾項須要修改
  Username     = mpm
  Password     = 123456
  MysqlHost    = 127.0.0.1
  MysqlPort    = 3306
  
  # Zabbix Server IP address 須要修改
  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 #這裏也須要修改
  
  [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：該行及如下的幾行須要取消註釋
  Type         = mysqld
  MysqlPort    = 3306
  Modules      = process mysql myisam innodb slave
  PidFile      = /var/run/mysqld/mysqld.pid
  Debug        = 1
  

  注:這裏監控的MySQL Server是MySQL主從複製的中的Slave機器.

 

查看mpm-agent的日誌會報錯，一個是mysql.pid文件讀取權限的問題，這個能夠自行解決。還有一個就是鏈接zabbix server的問題：解決方法以下：

安裝MySQL MPM插件時，在zabbix web前端點擊Monitoring->Latest data查看監控，沒有生成監控數據
查看MPM的日誌，發現下面報錯
[root@localhost etc]# tail -f /var/log/zabbix/FromDualMySQLagent.log
15989:2017-04-10 07:59:44.725 - INFO: FromDual Performance Monitor for MySQL (0.9.1) run started.

解決方法： 註釋掉Zabbix Agent端下面文件中的check語句 [root@localhost etc]# vim /usr/local/mysql_performance_monitor-agent/lib/sendData.pm #    $rc = &FromDualMySQLagent::checkConnectionToZabbixServer($main::gParameter{'ZabbixServer'}, $main::gParameter{'ZabbixServerPort'}, $main::gParameter{'Hostname'}); 以後關閉Agentd服務，刪除cache文件夾裏面的文件 [root@localhost cache]# cd /var/log/zabbix/cache [root@localhost cache]# rm -rf * 以後重啓Agentd服務
