#!/usr/bin/env python
#coding:utf-8

def sever_info(ip)
  cmd = "/usr/bin/ansible {ip} -m setup".format(ip=ip)
  raw_info = subprocess.check_output(cmd,shell=True)
  base_info = json.loads(raw_info.split(‘=>‘)[1])[‘ansible_facts‘]
  cpu = base_info[‘ansible_processor_vcpus‘]
  memory = round(int(base_info[‘ansible_memtotal_mb‘])/1024.0,1)
  disk_info = base_info[‘ansible_devices‘]
  disk_volume = sum([int(disk_info[disk][‘sectors‘])*int(disk_info[disk][‘sectorsize‘]) for disk in disk_info])/1024**3
  hostname = base_info[‘ansible_hostname‘]
  os = base_info[‘ansible_lsb‘][‘description‘]
  print cpu,memory,disk_info,disk_volume,hostname,os
if __name__=="__main__":
  sever_info(192.168.1.1)
