The Netdata url schema exposes all metrics being measured by Netdata as a JSON-exportable REST url.

querying netdata API

To obtain the data that Netdata is reading, then, is a simple matter of making a URL request and translating the result into JSON. This is a breeze with the Python 3 requests library:

import requests
my_url = 'http://10.6.0.1:19999/api/v1/allmetrics?format=json&help=yes'
r = requests.get(url=my_url)

# dump resulting json
with open(output.json','w') as f:
    json.dump( r.json(), f )

# print resulting json
print(r.json())

This displays a huge dictionary full of key-value pairs - all the quantities netdata is monitoring.
