Python从ZabbixAPI获取信息及实现Zabbix-API 监控的方法

Python编写从ZabbixAPI获取信息

此脚本用Python3.6执行是OK的。

下面看下使用python实现 Zabbix-API 监控的方法

做运维的朋友应该知道，公司IDC机房经常有上架、下架、报修和报废的服务器。如果服务器数量很多的时候很容易造成监控遗漏。

       大的互联网公司把监控系统和CMDB（资产管理系统|配置管理数据库系统）集成在一起，当上架一台新机器的时候CMDB里面会记录相关的信息，Zabbix根据CMDB里面信息自动Link相关的模块，添加|删除监控。很多小的公司没有资产管理系统，但作为监控的负责人应该每天知道上架了哪些新的机器，确保能添加到Zabbix监控里面。
      首先给大家说一下脚本思路：

1）通过Nmap工具扫描网段，扫描出已经使用的IP地址。
2）通过Nmap检测已经扫描IP的3389或者22端口是否开放，可以判断那些事windows机器，那些是Linux机器。
3）Linux下面通过ssh + hostname命令找出Linux主机名。
4）Windows下面通过nmblookup -A 命令找出Windows主机名。
5）用Python脚本读扫描结果文件，把主机名写到列表里面。
6）用Zabbix python API 调用已经监控的主机名，写到列表里面。
7）两个列表取交集，用for循环判断哪些主机名没有监控。
8）发邮件通知监控负责人。

    下面我分享一下我写的Python写的脚本，其中scan_machine.sh是我调用的用Shell写的关于Nmap扫描的脚本，scan_hostname.log是Nmap扫描的结果，里面内容是IP 主机名。

#!/usr/bin/env python#create by:sfzhang 20140820#coding=utf-8import os,sysimport jsonimport urllib2import datetime,timefrom urllib2 import URLError
nmap_cmd = "/shell/machine/scan_machine.sh"def runCmd(command):
 global mail_cmd
 mail_cmd = '''mail -s "Report on not monitor Hosts of Zabbix" shifeng_zhang88 < /shell/machine/result/result.txt'''
 return os.system(command)runCmd(nmap_cmd)def nmap_host():
 hostiplst = []
 hostnamelst = []
 f = file('/shell/machine/result/scan_hostname.log')
 for line in f.readlines():
 hostip = line.split()[0]
 hostname = line.split()[1]
 hostiplst.append(hostip)
 hostnamelst.append(hostname)
 hostnamelst.sort()
 #print hostiplst
 return hostnamelst
 f.close()def zabbix_host():
 zabbixhostlst= []
 #based url and required header
 url = "http://192.168.161.128/api_jsonrpc.php"
 header = {"Content-Type": "application/json"}
 #request json
 data = json.dumps(
 { 
 "jsonrpc": "2.0",
 "method": "host.get",
 "params":{
  "output":["hostid","name"],
  "filter":{"host":""}
 }, 
 #auth id
 "auth":"Zabbix Auth ID",
 "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:
 print "The server could not fulfill the request.",e.reason else:
 reponse = json.loads(result.read())
 result.close()
 #print "Number of Hosts:",len(reponse['result'])
 for host in reponse['result']:
  #print "Host ID:",host['hostid'],"Host Name:",host['name']
  zbxhosts=host['name']
  zabbixhostlst.append(zbxhosts)
 zabbixhostlst.sort()
 return zabbixhostlst def main():
 nmaphostlst = nmap_host() 
 zbxhostlst = zabbix_host() 
 diff = list(set(nmaphostlst) ^ set(zbxhostlst)) 
 content = "\n"
 nomonitorlst = [] 
 if len(diff) != 0: 
 for host in diff: 
  if host in nmaphostlst: 
  nomonitorlst.append(host)
 else: 
 sys.exit()
 #print zbxhostlst
 string = '\n'.join(nomonitorlst)
 f = file('/shell/machine/result/result.txt','w')
 f.write(string)
 f.flush()
 f.close()
 runCmd(mail_cmd)if __name__ == "__main__": 
 main()

   把脚本添加到crontab,每台会收到关于那些主机没有添加监控的信息。

 总结：

     1）Zabbix API相关信息可以查看官方详细资料，看不懂英文的可以参考下面这篇文档。http://paperplane.ruhoh.com/zabbix/intro-to-zabbix-api/

     2）通过该脚本可以知道那些主机没有添加监控，希望对大家有帮助，如果有更好的解决方法欢迎多多交流。
