zabbix數據庫表結構說明

actions

actions表記錄了當觸發器觸發時，須要採用的動做。

mysql> desc actions;

alerts

alerts 表保存了歷史的告警事件，能夠從這個表裏面去作一些統計分析，例如某個部門、 
某人、某類時間的告警統計，以及更深刻的故障發生、恢復時間

mysql> desc alerts;
+-------------+---------------------+------+-----+---------+-------+| Field       | Type                | Null | Key | Default | Extra |

+-------------+---------------------+------+-----+---------+-------+

config

config表保存了全局的參數，前端包括後端也是，不少狀況下會查詢改表的參數的，例如用戶的自定義主題、 
登錄認證類型等，很是重要，

不過對咱們作數據分析意義不大。

mysql> desc config;
+-------------------------+---------------------+------+-----+-----------------+-------+
| Field                   | Type                | Null | Key | Default         | Extra |

functions

function 表是一個很是重要的表，記錄了trigger中使用的表達式，例如max、last、nodata等函數。

同時記錄了trigger、itemid，能夠作一些API的開發了，例如根據IP查詢改IP的全部trigger。

mysql> desc functions ;
+------------+---------------------+------+-----+---------+-------+
| Field      | Type                | Null | Key | Default | Extra |
+------------+---------------------+------+-----+---------+-------+
| functionid | bigint(20) unsigned | NO   | PRI | 0       |       |
| itemid     | bigint(20) unsigned | NO   | MUL | 0       |       |
| triggerid  | bigint(20) unsigned | NO   | MUL | 0       |       |
| lastvalue  | varchar(255)        | YES  |     | NULL    |       |
| function   | varchar(12)         | NO   |     |         |       |
| parameter  | varchar(255)        | NO   |     | 0       |       |
+------------+---------------------+------+-----+---------+-------+

graphs

graphs 表包含了用戶定義的圖表信息，一樣的玩法能夠是根據IP去查詢改IP下的全部圖表， 
不過彷佛是有API的，這裏只是舉個例子。

mysql> desc graphs;
+------------------+---------------------+------+-----+---------+-------+
| Field            | Type                | Null | Key | Default | Extra |

| yaxismin         | double(16,4)        | NO   |     | 0.0000  |       |
| yaxismax         | double(16,4)        | NO   |     | 0.0000  |       |

| show_3d          | int(11)             | NO   |     | 0       |       |
| percent_left     | double(16,4)        | NO   |     | 0.0000  |       |
| percent_right    | double(16,4)        | NO   |     | 0.0000  |       |
| ymin_type        | int(11)             | NO   |     | 0       |       |
