使用zabbix自带模板监控 mysql

服务端配置

因zabbix-server监控mysql是通过zabbix-agent端的/etc/zabbix/.my.cnf配置文件，所以host只需要对localhost授权即可.

mysql> GRANT PROCESS,SUPER,REPLICATION CLIENT ON *.* TO zabbix@'localhost' IDENTIFIED BY 'zabbix';

mysql> flush privileges;

在zabbix-agent目录下 /etc/zabbix/ 创建 .my.cnf文件

vim /etc/zabbix/.my.cnf

[client]
user=zabbix
password=zabbixpassword

然后查看 userparameter_mysql.conf 文件，看到类似 HOME=/var/lib/zabbix 的路径设置，把路径全都替换为 /etc/zabbix/，使用下面的命令

sed -i 's|/var/lib/zabbix|/etc/zabbix|g' /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

客户端重启zabbix

/etc/init.d/zabbix-agent restart

测试

在服务端执行如下命令：

zabbix_get -s 192.168.14.130  -p 10050 -k "mysql.status[Uptime]"

zabbix_get -s 192.168.14.130 -p10050 -k mysql.status[Com_update]

之后在监控界面增加主机对应的MySQL模板。

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,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
