zabbix监控全国天气实况

微信公众号：运维开发故事，作者:wanger

本文主要通过一些监控示例来简单介绍zabbix的http agent类型的监控以及map图的简单用法，我们可以通过一些网站查询天气的api来获取天气情况，大部分的地图软件也都支持天气查询，这里我简单介绍几个，有高德地图，百度地图，心知天气，YY天气，个人用的是YY天气，因为我的需求不高，他能轻易地满足我
YY天气api地址：.html

创建HTTP agent类型的监控项

以创建北京天气的监控项为例

我们只要把请求的URL和键值填上就可以了

获取数据如下

我们可以根据获取的数据对json进行预处理

创建包含预处理的可依赖监控项

以监控天气信息为例

键值定义尽量规范，依赖项选择刚刚新建的http agent监控项

添加预处理步骤

根据刚才获取到的数据来获取tq的值

除此之外还需要定义气温、风力、风向、相对湿度，添加方法与上面相同

添加高温的触发器

编写脚本批量添加监控项和触发器

但是这样做要添加的监控项和触发器太多了，而且都是重复性的工作，这里我写了个脚本，来对各地城市的监控项和触发器进行批量添加，批量添加的好处是省时省力，而且减少出错概率。
实现思路是获取主机的接口id，并对城市进行循环添加监控项和触发器
