做过Zabbix的同学都知道,Zabbix通过专用的Agent或者SNMP收集相关的监控数据,然后存储到数据库里面实时在前台展示。Zabbix监控数据主要分为以下两类:历史数据:history相关表,从history_uint表里面可以查询到设备监控项目的最大,最小和平均值,即存储监控数据的原始数据。
趋势数据:trends相关表,趋势数据是经过Zabbix计算的数据,数据是从history_uint里面汇总的,从trends_uint可以查看到监控数据每小时最大,最小和平均值,即存储监控数据的汇总数据。
Zabbix可以通过两种方式获取历史数据:
1.通过Zabbix前台获取历史数据
通过Zabbix前台查看历史数据非常简单,可以通过Monitoring->Lastest data的方式查看。也可以点击右上角的As plain test按钮保存成文本文件。
2.通过前台获取的数据进行处理和二次查询有很多限制,因此可以通过SQL语句直接从后台DB查询数据。
首先大家应该熟悉SQL语句Select 常用用法:
SELECT [ALL | DISTINCT] Select_List [INTO [New_Table_name]
FROM { Table_name | View_name} [ [,{table2_name | view2_name}
[,…] ]
[ WHERE Serch_conditions ]
[ GROUP BY Group_by_list ]
[ HAVING Serch_conditions ]
[ ORDER BY Order_list [ASC| DEsC] ]
说明:
1)SELECT子句指定要查询的特定表中的列,它可以是*,表达式,列表等。
2)INTO子句指定要生成新的表。
3)FROM子句指定要查询的表或者视图。
4)WHERE子句用来限定查询的范围和条件。
5)GROUP BY子句指定分组查询子句。
6)HAVING子句用于指定分组子句的条件。
7)ORDER BY可以根据一个或者多个列来排序查询结果,在该子句中,既可以使用列名,也可以使用相对列号,ASC表示升序,DESC表示降序。
8)mysql聚合函数:sum(),count(),avg(),max(),avg()等都是聚合函数,当我们在用聚合函数的时候,一般都要用到GROUP BY 先进行分组,然后再进行聚合函数的运算。运算完后就要用到Having子句进行判断了,例如聚合函数的值是否大于某一个值等等。

从Zabbix数据库中查询监控项目方法,这里已查询主机的网卡流量为例子:
1)通过hosts表查找host的ID。
mysql>select host,hostid from hosts where host="WWW05"
+-------+--------+
| host | hostid |
+-------+--------+
| WWW05 | 10534 |
+-------+--------+
1 row in set (0.00 sec)
2)通过items表查找主的监控项和key以及itemid。
mysql>select itemid,name,key_ from items where hostid=10534 and key_="net.if.out[eth0]"
+--------+-----------------+------------------+
| itemid | name| key_ |
+--------+-----------------+------------------+
| 58860 | 发送流量: | net.if.out[eth0] |
+--------+-----------------+------------------+
1 row in set (0.00 sec)
3)通过itemid查询主机的监控项目(history_uint或者trends_uint),单位为M。
主机流入流量:
mysql>select from_unixtime(clock) as DateTime,round(value/1024/1024,2) as Traffic_in from history_uint where itemid="58855" and from_unixtime(clock)>='2014-09-20' and from_unixtime(clock)<'2014-09-21' limit 20
