通过Zabbix API获取历史监控数据

Zabbix API可以通过JSON RPC协议来获取历史数据。

可以采用脚本或者任何支持JSON RPC的工具来使用API。

基本请求格式

Zabbix API 简化的JSON请求如下：

{

   "jsonrpc": "2.0",

   "method": "method.name",

   "params": {

       "param_1_name": "param_1_value",

       "param_2_name": "param_2_value"

   },

   "id": 1,

   "auth": "a826fca79a0795ccc1224dc76329972f",

}

下面一行一行来看：

● "jsonrpc": "2.0"-这是标准的JSON RPC参数以标示协议版本。所有的请求都会保持不变。

● "method": "method.name"-这个参数定义了真实执行的操作。例如：host.create、item.update，history.get等等

● "params"-这里通过传递JSON对象来作为特定方法的参数。如果你希望创建监控项，"name"和"key_"参数是需要的，每个方法需要的参数在Zabbix API文档中都有描述。

● "id": 1-这个字段用于绑定JSON请求和响应。响应会跟请求有相同的"id"。在一次性发送多个请求时很有用，这些也不需要唯一或者连续

● "auth": "a826fca79a0795ccc1224dc76329972f"-这是一个认证令牌【authentication token】用以鉴别用户、访问API。这也是使用API进行相关操作的前提-获取认证ID。(以上为转载http://paperplane.ruhoh.com/zabbix/intro-to-zabbix-api/)

实例：获取192.168.211.60从2014.2.19 14:00:00到2014.2.19 14:10:00的cpu idle值

基于curl命令：

（1）：认证并且取得加密字段

curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":

"2.0","method":"user.login","params":{"user":"xxxx","password":"xxxx"},"auth":

null,"id":0}' http://x.x.x.x/api_jsonrpc.php

#之后会得到一串输出：{"jsonrpc":"2.0","result":"a826fca79a0795ccc1224dc76329972f","id":0}。记住这

段输出。

（2）获取监控主机的hostids

curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc": "2.0","method":"host.get","params":{"output":["hostid"],"filter": {"host":"192.168.211.60"}},"auth": "a826fca79a0795ccc1224dc76329972f","id": 0}' http://x.x.x.x/api_jsonrpc.php

#"hostid":"10243"

（3）获得监控项itemids

curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc": "2.0","method":"item.get","params":{"output":"itemids","hostids":"10243","search":{"key_":"system.cpu.util

[,idle,avg1]"}},"auth": "a826fca79a0795ccc1224dc76329972f","id": 0}' http://x.x.x.x/api_jsonrpc.php

#“item”:"24526"

(4)获取监控项"system.cpu.util[,idle,avg1]"在2014.2.19 14:00~14:20的值

curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc": "2.0","method":"history.get","params":{"history":0,"itemids":["24526"],"time_from":"1392789600","time_till":"1392790200","output":"extend"},"auth": "a826fca79a0795ccc1224dc76329972f","id": 0}' http://x.x.x.x/api_jsonrpc.php

#输出：

[{"itemid":"24526","clock":"1392789646","value":"95.7539","ns":"138978589"},

{"itemid":"24526","clock":"1392789706","value":"84.9595","ns":"578198422"},

{"itemid":"24526","clock":"1392789766","value":"94.5259","ns":"186216653"},

{"itemid":"24526","clock":"1392789826","value":"96.2286","ns":"789434167"},

{"itemid":"24526","clock":"1392789886","value":"94.7712","ns":"191954191"},

{"itemid":"24526","clock":"1392789946","value":"90.8338","ns":"781241168"},

{"itemid":"24526","clock":"1392790006","value":"89.1735","ns":"294674458"},

{"itemid":"24526","clock":"1392790066","value":"92.3015","ns":"877714419"},

{"itemid":"24526","clock":"1392790126","value":"96.3051","ns":"426421789"},

{"itemid":"24526","clock":"1392790186","value":"97.7931","ns":"174500891"}]

#“value”就是cpu idle值，采样间隔时间与监控项的数据更新时间一致。

补充：获取192.168.211.60监控项"system.cpu.util[,idle,avg1]"在2014年2月19日 下午2:02:46 的值

 curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc": "2.0","method":"history.get","params":{"history":0,"itemids":["24526"],"time_from":"1392789600","time_till":"1392790200","output":"extend","filter":{"clock":"1392789766"}},"auth": "a826fca79a0795ccc1224dc76329972f","id": 0}' http://x.x.x.x/api_jsonrpc.php

#"value":"94.5259"要获取的值
