# 环境说明 #

Centos 7.2

zabbix 3.2

mariadb 5.5.50

# 操作步骤 #

此次通过zabbix自有template “Template APP MYSQL”对 zabbix-agent中的mariadb进行监控

1.安装zabbix-agent参考 [《Centos 7下搭建Zabbix监控软件》][Centos 7_Zabbix]

2.在安装完成zabbix-agent后，我们可以在/etc/zabbix/zabbix\_agentd.d目录下面找到userparameter\_mysql.conf文件，其内容如下

# For all the following commands HOME should be set to the directory that has .my.cnf file with password information.
    
    # Flexible parameter to grab global variables. On the frontend side, use keys like mysql.status[Com_insert].
    # Key syntax is mysql.status[variable].
    UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'
    
    # Flexible parameter to determine database or table size. On the frontend side, use keys like mysql.size[zabbix,history,data].
    # Key syntax is mysql.size[<database>,<table>,<type>].
    # Database may be a database name or "all". Default is "all".
    # Table may be a table name or "all". Default is "all".
    # Type may be "data", "index", "free" or "both". Both is a sum of data and index. Default is "both".
    # Database is mandatory if a table is specified. Type may be specified always.
    # Returns value in bytes.
    # 'sum' on data_length or index_length alone needed when we are getting this information for whole database instead of a single table
    UserParameter=mysql.size[*],bash -c '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 -N'
    
    UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping | grep -c alive
    UserParameter=mysql.version,mysql -V

在修改该配置文件之前，我们需要在/var/lib/zabbix目录下面，新建maraidb数据库的配置文件\[client\]部分

[root@ovirt-host-227 zabbix_agentd.d]# vi /var/lib/zabbix/.my.conf 
    [client]
    
    user=root
    
    password=123456

而后重启zabbix-agent

#systemctl restart zabbix-agent

3.我们在zabbix-server端，通过zabbix\_get来测试下在zabbix-server端是否能获取在zabbix-agent中关于mariadb的数据

[root@centos7-zabbix-193 ~]# zabbix_get -s 10.10.200.227 -k mysql.status[Bytes_received]                                                                                                                                                                                  
    2835903
    [root@centos7-zabbix-193 ~]# zabbix_get -s 10.10.200.227 -k mysql.status[Com_update]                                                                                                                                                                                      
    0

通过以上可以正确的获取mariadb的数据，下面在zabbix web console端配置Host端的Template

4.将“Template APP MySQL”加入Host的Template中

在加入后，我们分别查看item以及graphs

![Center 1][]

![Center 2][]

我们分别查看MySQL operations以及Mysql bandwidth

![Center 4][]

![Center 5][]

点击preview

![Center 6][]

通过两个graphs均可将mariadb的性能数据进行显示。
