zabbix数据库表结构的重要性
想理解zabbix的前端代码、做深入的二次开发，甚至的调优，那就不能不了解数据库的表结构了。

+---------------+---------------------+------+-----+---------+-------+
alerts
alerts 表保存了历史的告警事件，可以从这个表里面去做一些统计分析，例如某个部门、
某人、某类时间的告警统计，以及更深入的故障发生、恢复时间，看你想怎么用了。
mysql> desc alerts;
+-------------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |

| alerttype | int(11) | NO | | 0 | |
+-------------+---------------------+------+-----+---------+-------+
config
config表保存了全局的参数，前端包括后端也是，很多情况下会查询改表的参数的，例如用户的自定义主题、
登陆认证类型等，非常重要，
不过对我们做数据分析意义不大。
mysql> desc config;
+-------------------------+---------------------+------+-----+-----------------+-------+

| max_in_table | int(11) | NO | | 50 | |
| search_limit | int(11) | NO | | 1000 | |
+-------------------------+---------------------+------+-----+-----------------+-------+
functions
function 表时非常重要的一个表了，记录了trigger中使用的表达式，例如max、last、nodata等函数。
但其实这个表说他重要时因为同时记录了trigger、itemid，那就可以做一些API的开发了，例如根据
IP 茶香改IP的所有trigger，我记得1.8的版本的API是无法实现我说的这个功能的，那只能利用
function表去自己查询了。
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 表包含了用户定义的图表信息，同样的玩法可以是根据IP去查询改IP下的所有图表，
不过似乎是有API的，我只是举例而已。
mysql> desc graphs;
+------------------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------------+---------------------+------+-----+---------+-------+
| graphid | bigint(20) unsigned | NO | PRI | 0 | |
| name | varchar(128) | NO | MUL | | |
| width | int(11) | NO | | 0 | |

| graphtype | int(11) | NO | | 0 | |
| show_legend | int(11) | NO | | 0 | |
| 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 | |
| ymax_type | int(11) | NO | | 0 | |
| ymin_itemid | bigint(20) unsigned | NO | | 0 | |
| ymax_itemid | bigint(20) unsigned | NO | | 0 | |
+------------------+---------------------+------+-----+---------+-------+
graphs_items
graphs_items 保存了属于某个图表的所有的监控项信息。
mysql> desc graphs_items;
+-------------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+---------------------+------+-----+---------+-------+
| gitemid | bigint(20) unsigned | NO | PRI | 0 | |
| graphid | bigint(20) unsigned | NO | MUL | 0 | |
| itemid | bigint(20) unsigned | NO | MUL | 0 | |
| drawtype | int(11) | NO | | 0 | |
| sortorder | int(11) | NO | | 0 | |
| color | varchar(6) | NO | | 009600 | |
| yaxisside | int(11) | NO | | 1 | |
| calc_fnc | int(11) | NO | | 2 | |
| type | int(11) | NO | | 0 | |
| periods_cnt | int(11) | NO | | 5 | |
+-------------+---------------------+------+-----+---------+-------+
groups
groups 没啥说的，都懂，就是保存了组名和组的ID 。
mysql> desc groups ;
+----------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+---------------------+------+-----+---------+-------+
| groupid | bigint(20) unsigned | NO | PRI | 0 | |
| name | varchar(64) | NO | MUL | | |
| internal | int(11) | NO | | 0 | |
+----------+---------------------+------+-----+---------+-------+
history 、history_str、history_log 、history_uint_sync等
这部分表都差不多，唯一不同的是保存的数据类型，history_str保存的数据
类型就算str即字符类型的。这个是和采集时设置的数据类型一致的。
需要注意的时，因为history表有这么多的类型，那自己写报表系统等去查询
数据时，就需要判断下数据的采集类型，如果查错了表，那肯定时没有数据的。
mysql> desc history;
+--------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------+---------------------+------+-----+---------+-------+
| itemid | bigint(20) unsigned | NO | PRI | 0 | |
| clock | int(11) | NO | PRI | 0 | |
| value | double(16,4) | NO | | 0.0000 | |
+--------+---------------------+------+-----+---------+-------+ mysql> desc history_str;
+--------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------+---------------------+------+-----+---------+-------+
| itemid | bigint(20) unsigned | NO | MUL | 0 | |
| clock | int(11) | NO | | 0 | |
| value | varchar(255) | NO | | | |
+--------+---------------------+------+-----+---------+-------+
接收item值时的时间值存放在两个字段内，大于1秒的部分存放找clock字段单位是秒(s)，小于一秒的部分存放在ns字段单位是纳秒(ns)。
两个字段相加的值才是接收item值时的时间值，一般不用关心小于1秒的部分。
trends、trends_uint
trends 也是保存了历史数据用的，和history不同的时，trends表仅仅保存了
小时平均的值，即你可以理解为是history表的数据压缩。所以trends表也有
很多的类型，对应history。
值的注意的trends和history表这两类表数据量都非常大，我们一天大概就要有
40G 的数据。
所以注意定是去做压缩、删除。
mysql> desc trends;
+-----------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------+---------------------+------+-----+---------+-------+
| itemid | bigint(20) unsigned | NO | PRI | 0 | |

| num | int(11) | NO | | 0 | |
| value_min | double(16,4) | NO | | 0.0000 | |
| value_avg | double(16,4) | NO | | 0.0000 | |
| value_max | double(16,4) | NO | | 0.0000 | |
+-----------+---------------------+------+-----+---------+-------+ mysql> desc trends_uint;
+-----------+---------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------+---------------------+------+-----+---------+-------+
| itemid | bigint(20) unsigned | NO | PRI | 0 | |
| clock | int(11) | NO | PRI | 0 | |
| num | int(11) | NO | | 0 | |
| value_min | bigint(20) unsigned | NO | | 0 | |
| value_avg | bigint(20) unsigned | NO | | 0 | |
| value_max | bigint(20) unsigned | NO | | 0 | |
+-----------+---------------------+------+-----+---------+-------+
hosts
hosts 非常重要，保存了每个agent、proxy等的IP 、hostid、状态、IPMI等信息，
几乎是记录了一台设备的所有的信息。
当然hostid是当中非常非常重要的信息，其他的表一般都时关联hostid的。
mysql> desc hosts;
+--------------------+---------------------+------+-----+-----------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------------+---------------------+------+-----+-----------+-------+
| hostid | bigint(20) unsigned | NO | PRI | 0 | |

| ipmi_available | int(11) | NO | | 0 | |
| snmp_disable_until | int(11) | NO | | 0 | |
| snmp_available | int(11) | NO | | 0 | |
| maintenanceid | bigint(20) unsigned | NO | | 0 | |
| maintenance_status | int(11) | NO | | 0 | |
| maintenance_type | int(11) | NO | | 0 | |

| ipmi_ip | varchar(64) | NO | | 127.0.0.1 | |
| ipmi_errors_from | int(11) | NO | | 0 | |
| snmp_errors_from | int(11) | NO | | 0 | |
| ipmi_error | varchar(128) | NO | | | |
| snmp_error | varchar(128) | NO | | | |
+--------------------+---------------------+------+-----+-----------+-------+
其实1.0的版本中，是没有这么多的字段的，好像只有hostid、host、status、disable_until
等几个字段，但1.8已经如此丰富了。
hosts_groups
hosts_groups 保存了host（主机）与host groups（主机组）的关联关系。
这部分信息可以在我们自己做一些批量查询，例如查询关联到某个主机组的所有
设备的IP 、存活状态等，进一步去查询该批量设备的load、IO、mem等统计信息。
我之前做的一个简单的报表就是例如了这部分的信息去查询某个业务线下所有设备
的一周统计信息，当然了是在同一个主机组或者模版组才可以的。
mysql> desc hosts_groups ;
