Zabbix配合fpmmm(mpm)实现对Mysql的全面监控

               

                            Zabbix使用fpmmm(mpm)模块实现对Mysql的全面监控

                                       (Performance Monitor for MySQL)

 

fpmmm is the FromDualPerformance Monitor for MySQL and MariaDB and the counterpart to the MySQL EnterpriseMonitor from Oracle.With fpmmm you can monitor your MySQL/MariaDB databases andalso your database hosts (machines).fpmmm works on Linux and should also workon Mac OSX (and possibly some other *BSD derivatives). Windows support is plannedfor the next major release.fpmmm is the successor of mpm. mpm was renamed tofpmmm because of the naming conflict with the Apache Multi-Processing Modules(MPM).fpmmm needs a Zabbix Server for storing its performance data. There youcan see the graphs, and alerts are sent to you from there.

上话摘自官网,简单来说mpm改名为fpmmm,可配合zabbix监控数据库。用了一段时间后感觉挺好使的。使用fpmmm可以很全面的监控mysql数据库。

被监控主机操作: 

1.安装依赖的程序包:

[root@test-master-mysql-42 bin]# yum install php-cli php-process php-mysqli


2.下载fpmmm

http://down.51cto.com/data/2239742

https://support.fromdual.com/admin/public/download.php?product_id=0

 

[root@test-app-server-130 install]#

wget https://support.fromdual.com/admin/download/fpmmm-0.10.6.tar.gz

wKiom1fPluTDbRS3AAA0C5hQISY152.png


3.解压:

[root@test-app-server-130 install]# tar -xvf fpmmm-0.10.6.tar.gz

wKioL1fPlu6yKOzrAAAXCMTju0E376.png

 

4.移动到部署位置:

[root@test-app-server-130 install]# mv fpmmm-0.10.6 /data/server/zabbix_agent/fpmmm/

wKiom1fPlvux9AiEAAAMiiT5wpg140.png

[root@test-app-server-130 install]# cd /data/server/zabbix_agent/fpmmm/

[root@test-app-server-130 fpmmm]# ls

bin CHANGELOG  INSTALL  lib tpl

 

5.mysql创建监控帐号:

mysql> grant PROCESS,REPLICATION CLIENT,REPLICATION SLAVE on *.* to zabbix_fpmmm@'127.0.0.1' identified by '密码';

mysql> grant select on mysql.user to zabbix_fpmmm@'127.0.0.1';

 

6.创建并修改配置文件:

(注意:事例里配置的目录上一级已存在,自己在搭建时注意目录是否存在,若嫌麻烦和权限问题可以都放在tmp目录)

[root@test-app-server-130 fpmmm]# cp -pr  tpl/fpmmm.conf.templatetpl/fpmmm.conf

[root@test-app-server-130 fpmmm]# vim tpl/fpmmm.conf

7.第一次尝试运行:

[root@test-master-mysql-42 bin]#/data/server/zabbix_agent/fpmmm/bin/fpmmm --config=/data/server/zabbix_agent/fpmmm/tpl/fpmmm.conf

PHP Notice: Undefined index: PATH in /data/server/zabbix_agent/fpmmm/bin/fpmmm.phpon line 29

PHP Notice: Undefined index: PATH in /data/server/zabbix_agent/fpmmm/bin/fpmmm.phpon line 29

PHP Warning:  gettimeofday(): It is not safe to rely on thesystem's timezone settings. You are *required* to use the date.timezone settingor the date_default_timezone_set() function. In case you used any of those methodsand you are still getting this warning, you most likely misspelled the timezoneidentifier. We selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in/data/server/zabbix_agent/fpmmm/lib/log.inc on line 103

 

这里有两个问题:

 1).php时区错误。

解决方法:

修改php.ini,在php.ini中找到;date.timezone=  去掉它前面的;号,然后设置data.timezone= "Asia/Shanghai";

[root@test-master-mysql-42~]# vim /etc/php.ini

wKioL1fPlyrDmjPkAAAaCxDTdyQ594.png

 

 2).未找到zabbix_sender。

可以再次执行命令的同时监控日志(tail -f /data/logs/zabbix/fpmmm.log)看到报错信息:7887:2016-09-0621:35:11.983 - ERR :       which: nozabbix_sender in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/data/server/mysql/bin:/root/bi)


解决方法:在/usr/local/bin/添加zabbix_sender软链接

[root@test-master-mysql-42 ~]# ln -s /data/server/zabbix_agent/bin/zabbix_sender /usr/local/bin/

同时注释掉/data/server/zabbix_agent/fpmmm/bin/fpmmm.php的第29行。

8. 第二次运行:

[root@test-master-mysql-42 bin]#/data/server/zabbix_agent/fpmmm/bin/fpmmm --config=/data/server/zabbix_agent/fpmmm/tpl/fpmmm.conf

1

没有报错,日志也正常(tail -f /data/logs/zabbix/fpmmm.log)。

 

9. 但是,在测试运行后需要修改几个文件的权限和所属者,不然在以后的运行中会报错:

1). 修改新产生的cache文件权限:

[root@test-master-mysql-42 zabbix_agent]# chown zabbix.zabbix /data/server/zabbix_agent/fpmmm/ -R

wKioL1fPl0WwUvxWAABcMKdn1q0602.png

2). 修改日志权限:

[root@test-master-mysql-42 logs]# chown zabbix.zabbix /data/logs/zabbix/ -R

wKioL1fPl1CwsYsQAAAZezOiLo8901.png

3).修改mysqlpid权限让zabbix可读(但下次mysql重启后pid权限会改变),或直接把zabbix用户加到mysql组:

[root@test-master-mysql-42 ~]# chmod 664 /data/server/mysql/data/mysql.pid

[root@test-master-mysql-42 ~]# usermod -a -G mysql zabbix


注意:在删除日志后需要重新给权限,有问题一定要看日志,根据日志报错来排查。


 

10.修改zabbixagent配置文件,在最末尾添加键值:

[root@test-master-mysql-42  fpmmm]# vim 

/data/server/zabbix_agent/etc/zabbix_agentd.conf

UserParameter=FromDual.MySQL.check,/data/server/zabbix_agent/fpmmm/bin/fpmmm--config=/data/server/zabbix_agent/fpmmm/tpl/fpmmm.conf

wKiom1fPl2LjOT62AAB2EsRzrG0483.png

重启zabbix-aget服务。

 

 

11.导入模版

模版就在下载的安装包的tpl目录

wKioL1fPl2-B3_9nAABPnrSBejQ021.png

下载后解压出模板导入

wKioL1fPl3mzijQuAAAww18FEJ0835.png

 

只需要导入需要的就行,可以导入:

Template_FromDual.MySQL.server.xml  Template_FromDual.MySQL.innodb.xml Template_FromDual.MySQL.master.xmlTemplate_FromDual.MySQL.mysql.xml  Template_FromDual.MySQL.process.xml  Template_FromDual.MySQL.server.xml  Template_FromDual.MySQL.slave.xml

 

 

12.添加主机:

wKiom1fPl4HA4BT9AABBCFuXGyI911.png

wKioL1fPl5XS0_AXAAApZJUT9Sk553.png

添加完毕后,可以去最新数据里看是否收到数据

wKiom1fPl5_Qj17XAAAq4YbyPIM716.png

 


 

13.添加到计划任务:

遇到没有数据的情况,将fpmmm加到crontab计划任务发送数据到zabbix_server(需要添加SHELL和PATH),如下:

执行set命令获取PATH:

wKiom1mWuC7ifYtMAABMWbVS0n8716.jpg-wh_50


[root@test-master-mysql-42  fpmmm]# crontab -e

*/2 * * * * SHELL=/bin/bash;PATH=/data/server/java/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/curl/bin:/root/bin;/bin/bash /data/server/zabbix_agent/fpmmm/bin/fpmmm  --config=/data/server/zabbix_agent/fpmmm/tpl/fpmmm.conf >/dev/null
