zabbix部署完之后
zabbix-agent操作
|
1
|
[root@localhost ~]# yum -y install mariadb mariadb-server |
2.编写mysql监控项的脚本
在zabbix-agent先授权个用户 不然测试时没有权限

[root@localhost ~]# mysqlwelcome to the mariadb monitor. commands end with ; or \g.your mariadb connection id is 33server version: 5.5.65-mariadb mariadb servercopyright (c) 2000, 2018, oracle, mariadb corporation ab and others.type 'help;' or '\h' for help. type '\c' to clear the current input statement.mariadb [(none)]> grant all on *.* to 'check'@'localhost' identified by '123';query ok, 0 rows affected (0.00 sec) |
mysql监控的内容主要有
- 主从的状态 (得先配置主从 在下面)
- 流量检测 发送，接受常规操作 增删改查
- 某个库、某个表的大小
- tps(每秒查询处理的事务数）qps(每秒能处理多少次请求数)

zabbix页面上添加监控项和图形
查看mysql流量数据
查看mysql qps tps
查看mysql主从状态
查看mysql常规操作
查看mysql库表大小
