zabbix3监控mysql性能状态

如果被监控的主机上已经安装好了mysql，在安装zabbix-agent的时候就会自动创建一个userparameter_mysql.conf

配置zabbix目录

vim /etc/zabbix/zabbix_agentd.conf
#取消注释,没有则创建一个
Include=/etc/zabbix/zabbix_agentd.d/

修改mysql监控的的配置

vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'

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

修改my.cnf 配置

# Zabbix Agent ;注意sock文件路径
[mysql]
host     = localhost
user     = zabbix
password = 密码
socket   = /var/run/mysqld/mysqld.sock
[mysqladmin]
host     = localhost
user     = zabbix
password = 密码
socket   = /var/run/mysqld/mysqld.sock
