关于API
zabbix拥有完善的API,基于JSON RPC提供资产,主机,主机组,监控项,告警等方面的接口。在做运维自动化时,需要用API功能对zabbix二次开发。本文我将介绍如何用python信使用zabbix的API。
API介绍:
API地址:http://你的zabbix域名/api_jsonrpc.php
API请求方法,采用POST
API请求数据结构
{
"jsonrpc": "2.0", // 版本
"method": "user.login", // 接口方法名
"params": {
//接口参数
},
"auth": "", // 登录后的session,未登录为空
"id": 1 // 任意数
}
API常用的接口
user.login ,用户登录
host.get(create|delete|update),主机操作
hostgroup.get(create|delete|update),主机组操作
item.getcreate|delete|update),监控项目操作
history.get,历史数据查询
event.get,事件查询
trigger.get ,触发器查询
近日公司准备自已做一个运维管理平台,其中的监控部分,打算调用zabbix api接口来进行展示。
经过思考之后,计划获取如下内容:
1、 获得认证密钥
2、 获取zabbix所有的主机组
3、 获取单个组下的所有主机
4、 获取某个主机下的所有监控项
5、 获取某个监控项的历史数据
6、 获取某个监控项的最新数据
计划最后展示框架如下内容(这只是值方面,其它的会再加):
主机组1 ----主机名1---监控项1----当前值
---监控项2----当前值
----主机名2----监控项1----当前值
----监控项2----当前值
主机组2 ----主机名3---监控项1----当前值
---监控项2----当前值
----主机名4----监控项1----当前值
----监控项2----当前值
进入正题
user.login方法获取zabbix server的认证结果
官方地址:```
https://www.zabbix.com/documentation/2.2/manual/api/reference/user/login
python脚本:
[root@yang python]# cat auth.py
#!/usr/bin/env python2.7
#coding=utf-8
import json
import urllib2
# based url and required header
url = "http://1.1.1.1/zabbix/api_jsonrpc.php"
header = {"Content-Type":"application/json"}
# auth user and password
data = json.dumps(
{
"jsonrpc": "2.0",
"method": "user.login",
"params": {
"user": "Admin",
"password": "zabbix"
},
"id": 0
})
# create request object
request = urllib2.Request(url,data)
for key in header:
request.add_header(key,header[key])
# auth and get authid
try:
result = urllib2.urlopen(request)
except URLError as e:
print "Auth Failed, Please Check Your Name AndPassword:",e.code
else:
response = json.loads(result.read())
result.close()
print"Auth Successful. The Auth ID Is:",response['result']
python脚本运行结果:
[root@yang python]# python auth.py
Auth Successful. The Auth ID Is: a0b82aae0842c2041386a61945af1180
curl命令:
curl -i -X POST -H 'Content-Type:application/json' -d '{"jsonrpc":
"2.0","method":"user.login","params":{"user":"admin","password":"zabbix"},"auth":
null,"id":0}' http://1.1.1.1/zabbix/api_jsonrpc.php
curl命令运行结果:
{"jsonrpc":"2.0","result":"b895ce91ba84fe247e444817c6773cc3","id":0}
把认证密钥放到脚本中,每次获取数据时都需要认证。此处是获取zabbix server上的所有主机组名称与ID号。
官方地址:https://www.zabbix.com/documentation/2.2/manual/api/reference/hostgroup/get

},
"auth":"3c0e88885a8cf8af9502b5c850b992bd", # theauth id is what auth script returns, remeber it is string
"id":1,
})
create request object
request = urllib2.Request(url,data)
for key in header:
request.add_header(key,header[key])
get host list
try:
result = urllib2.urlopen(request)
except URLError as e:
if hasattr(e, 'reason'):
print 'We failed to reach a server.'
print 'Reason: ', e.reason
elif hasattr(e, 'code'):
print 'The server could not fulfill the request.'
print 'Error code: ', e.code
else:
response = json.loads(result.read())
result.close()
print "Number Of Hosts: ", len(response['result'])
#print response
for group in response['result']:
print "Group
ID:",group['groupid'],"\tGroupName:",group['name']

itemsid.get方法获取单个主机下所有的监控项ID
根据标题3中获取到的所有主机id与名称,找到你想要获取的主机id,获取它下面的所有items。

history.get方法获取单个监控项最后的值
只需把上个脚本中或curl中的limit参数改为1就可。
此时监控项的数据已拿到了,接下来的把它传给前台展示就行了。
