1、安装部署Zabbix

2、MPM(PERFORMANCE MONITOR FOR MYSQL)依赖的相关Perl模块安装:

# yum install -y perl-File-Which perl-libwww-perl perl-Digest-SHA1 perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay  zabbix-sender

下载MPM并解压

解压缩软件包后，会发现有两个文件mysql_performance_monitor_agent-0.9.3.tar.gz和mysql_performance_monitor_templates-0.9.3.tar.gz。

其中mysql_performance_monitor_agent-0.9.3.tar.gz是放在监控机器上的配置信息

mysql_performance_monitor_templates-0.9.3.tar.gz则是要让我们导入到zabbix server的模板数据。

wget http://www.shinguz.ch/download/mysql_performance_monitor-latest.tar.gz

tar zxvf mysql_performance_monitor-latest.tar.gz

server端配置

3、Zabbix Web UI导入MPM模板

MPM模板:

# tar zxvf mysql_performance_monitor_templates-0.9.1.tar.gz

# sz mysql_performance_monitor_templates-0.9.1.tar.gz

# cd mysql_performance_monitor_templates-0.9.1/xml

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)

创建 Host groups，例如随便一个名字:GZNWMySQL

将已有的mysql机器(GZNWX-CASH-DB01)加入到GZNWMySQL组

值得注意的是:Hostname必须与MPM agent配置中的所使用的一致

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.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.process.xml (监控各种Linux进程[比如:mysqld,ndbd])

将上面的这个5个模板关联到GZNWX-CASH-DB01

agent端配置

安装MPM和配置MPM Agent的Zabbix Keys

安装MPM:

yum install -y perl-File-Which perl-libwww-perl perl-Digest-SHA1 perl-DBD-MySQL perl-Time-HiRes perl-Crypt-SSLeay  zabbix-sender

wget http://www.shinguz.ch/download/mysql_performance_monitor-latest.tar.gz

tar zxvf mysql_performance_monitor-latest.tar.gz

# 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

将MPM Agent的Keys配置添加到Zabbix Agentd配置文件中

cat >> /etc/zabbix/zabbix_agentd.conf << EOF

UnsafeUserParameters=1

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

EOF

配置MPM Agent:

cd /usr/local/mysql_performance_monitor-agent/etc

cp FromDualMySQLagent.conf.template /etc/zabbix/FromDualMySQLagent.conf

mkdir -p /var/log/zabbix /var/log/zabbix/cache

chown -R zabbix:zabbix /var/log/zabbix /var/log/zabbix/cache

给予zabbix对mysql的pid文件的读权限和MPM日志的权限

chmod o+r /data/mysql/mysql3306/tmp/mysql.pid

touch /var/log/zabbix/FromDualMySQLagent.log

chown -R zabbix:zabbix /var/log/zabbix

修改MPM配置文件

[root@oneproxy-vm zabbix]# cat /etc/zabbix/FromDualMySQLagent.conf

cat /etc/zabbix/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:

Username = zabbix

Password = zabbix

MysqlHost = 127.0.0.1

MysqlPort = 3306

# Zabbix Server IP address

ZabbixServer = 192.168.0.22

# 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 = server mysql innodb process

# Special parameter which is used for module ndb and process

ClusterLog = /var/lib/mysql-cluster/ndb_1_cluster.log

PidFile = /ngbs/data/GZNWX-CASH-DB01.pid

# If you want to use Monitoring as a Service:

# MaaS = on

# Hash =

# Methodes are: direct, http, email. Currently only http works

# Methode = http

# Url = http://support.fromdual.com/maas/receiver.php

#[db_server]

#Type = mysqld

#Modules = server mysql innodb process

# All MySQL databases here

# Try to avoid section names with spaces!

[GZNWX-CASH-DB01] # This MUST match Hostname in Zabbix!

Type = mysqld

MysqlPort = 3306

Modules = server mysql innodb process

PidFile = /ngbs/data/GZNWX-CASH-DB01.pid

# [mysql-5.1.41-ndb-7.0.13] # This MUST match Hostname in Zabbix!

#

# Type = mysqld

#

# MysqlPort = 3306

# Modules = slave

# PidFile = /var/lib/mysql/db_server.pid

# Debug = 0

# Disabled = false

# [mariadb-5.2.0] # This MUST match Hostname in Zabbix!

#

# Type = mysqld

#

# MysqlPort = 3306

# Modules = pbxt

# PidFile = /var/lib/mysql/db_server.pid

# All MySQL clusters here

# [cl_2_3] # This MUST match Hostname in Zabbix!

#

# Disabled = false

#

# Type = ndbd

# ClusterLog = /usr/local/mysql-cluster/ndb_1_cluster.log

#

# Modules = ndb process

#

# MysqlHost = 127.0.0.1

# MysqlPort = 3306

重启zabbix-agent即可

/etc/init.d/zabbix-agent restart

MPM agent 文件的配置要对应Zabbix agent文件的配置

sender

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

查看日志FromDualMySQLagent.log

问题一 ：[Z3001] connection to database 'zabbix' failed:

在被监控机器加用户

grant all privileges on *.* to zabbix@'%' identified by 'zabbix'

问题二： 要写被监控主机名

cat /etc/zabbix/FromDualMySQLagent.conf

[GZNWX-CASH-DB01] # This MUST match Hostname in Zabbix! 被监控主机的名字，跟zabbix里的host的名字要一致

Type = mysqld

MysqlPort = 3306

Modules = server mysql innodb process

PidFile = /ngbs/data/GZNWX-CASH-DB01.pid 被监控主机的mysql的pid文件

问题三：测试

测试，返回1则正常

在被监控机器上执行一下

/usr/local/mysql_performance_monitor-agent/FromDualMySQLagent.pl /etc/zabbix/FromDualMySQLagent.conf

在zabbix服务器上执行一下

zabbix_get -s 192.168.0.21 -p10050 -k "FromDual.MySQL.check"

问题四：Load of cache file failed. rc=1301

1、删除cache目录下所有文件并重启zabbix-agentd

rm -f /var/log/zabbix/cache/*

2、注释源码

vi /usr/local/mysql_performance_monitor-agent/lib/sendData.pm

$rc = &FromDualMySQLagent::checkConnectionToZabbixServer($main::gParameter{'ZabbixServer'}, $main::gParameter{'ZabbixServerPort'}, $main::gParameter{'Hostname'});

3、cat /etc/zabbix/FromDualMySQLagent.conf 里面Modules不能写mpm

Modules = server mysql innodb process
