Page Comparison

In this worked example, we will produce the same CSV file output as in the first PowerShell worked example. 

...

import requests

r = requests.get('http://vm-mike-2012b/api/v1/devices',auth=('admin','password'))
max = r.headers['X-fetch-count']
data = r.json()
count = len(data)

By default the REST API "/api/v1/devices" page will return 200 devices at a time. We can increase or decrease this using the "fetch_size" parameter. The variable max contains the total number of devices. If this is more than 200 we would need to fetch a second batch - see other worked examples in this series for more details on that. In this example we will print at most 200. data holds the RestAPI data converted into a Python data structure, count is the number of devices returned.

...

  url2 = row['self']
  r2 = requests.get(url2,auth=('admin','password'))
  device = r2.json()
  if ('total_memory_mb' in device):
    ram = device['total_memory_mb']
  else:
    ram = '(unknown ram)'

  if ('cpu' in device):
    
    cpu = device['cpu'][0]['cpu_model']
  else:
    cpu = '(unknown cpu)'

  # remove commas from the cpu string
  cpu = cpu.replace(',','')
  print (hostname,',',ram,',',cpu,sep='')
  i+=1
