使用Zabbix监控MySQL服务

mysql端的设置：

一般新版的zabbix都默认带了mysql的监控项目
在安装目录下zabbix_agentd.d/userparameter_mysql.conf

[root@server zabbix_agentd.d]# more userparameter_mysql.conf
# 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,d
ata].
# 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[*],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
[root@server zabbix_agentd.d]#

mysql的连接密码需要保存在 /var/lib/zabbix/.my.cnf

[root@server ~]# more /var/lib/zabbix/.my.cnf
[mysql]
host=127.0.0.1
port=3306
user=root
password=passwd
[root@server ~]#

这个文件用于制定Zabbix Agent如何获取MySQL数据

zabbix server端需要添加模板，新版的已经自带了，如果没有请下载下面的模板
Template_App_MySQL-2.2.0.xml

然后在Zabbix服务器的前端Web界面的组态->模板页面中选择汇入

这样我们在被监控端的设置就完成了，现在只需要在Zabbix前端将MySQL模板添加到需要监控的主机项中就可以开始监控了。
