Zabbix API delete host

               为了应对春节的购票潮，业务从各个层面都添加了很多服务器，现在好了，春节过了，要摘除了，好几百台要从 zabbix-server 下线，尼玛，好几百台啊
               这是要累死我的节奏啊，还好早早有准备，春节期间就又温习了api文档，用于应对 “下线危机".

                zabbix api delete host 步骤：
                1.  首先要获取到 zabbix-agent hostname 名称
                2.  通过 hostname 查询到 ["hostid"]
                3.  通过 ["hostid"] delete 主机

                
                 setp 1   批量获取 zabbix-agent hostname

        ansible -i discount_web -a "grep -oP '(?<=Hostname=)\S+' /etc/zabbix/zabbix_agentd.conf" all | grep [0-9]$ >> discount_web-Name

          [root@ansible-53_26 discount_web]# cat discount_web-Name 
          discount_web-79-187
          discount_web-79-186
          discount_web-79-189
          discount_web-79-188
          discount_web-79-192
          discount_web-79-190
          discount_web-79-198
          discount_web-79-191
          discount_web-79-195
          discount_web-79-193
          discount_web-79-197
          discount_web-79-194
          discount_web-79-199
          
         拿到列表，步骤一 完美实现.

                 setp 2 查看api json串构建格式
                 

         获取主机信息,方法 : host.get

         Request:

         {
            "jsonrpc": "2.0",
            "method": "host.get",
            "params": {
                "output": "extend",
                "filter": {
                "host": [
                       "Zabbix server",
                       "Linux server"
                        ]
                           }
                      },
            "auth": "038e1d7b1735c6a5436ee9eae095879e",
            "id": 1
         }

          
          删除主机 方法 ： host.delete

          request

          {
                "jsonrpc": "2.0",
                "method": "host.delete",
                "params": [
                          "13",
                          "32"
                          ],
                "auth": "038e1d7b1735c6a5436ee9eae095879e",
                "id": 1
           }

          params 那里显示了，当我们删除多个主机时，只需要提交一个 hostid list ，就可以删除，列表内的所有 agent.
          

                   setp 3 python 搓脚本，着急实现功能，拿以前的脚本改了改
                  

#!/usr/bin/env python2.7

                       "password": passwd
                           },
                "id": 0
              }
          )

      try:
           req = requests.post(url,auth,headers=header)

                         "filter": {
                               "host": host
                                   }
                         },
                     "auth": authtoken,
                     "id": 0
                   }
            )
            info = requests.post(url,query,headers=header)

            hostid=info.json()['result'][0]['hostid'].encode('utf8')
            hostlist.append(hostid)

     print hostlist

     query = json.dumps(
           {
             "jsonrpc": "2.0",
             "method": "host.delete",
             "params": hostlist,
             "auth": authtoken,
             "id": 0
           }
      )


    requests.post(url,query,headers=header)

if __name__ == '__main__':
   url = ""
   header = {"Content-Type": "application/json"}
   delete("Username","Password")
