Use the SevOne REST API (available for SevOne NMS 5.6+) to gather all the metrics (Indicators) from all devices. This is a starting point to develop more robust SevOne export solutions via REST

sevone_rest_metric_export.py

import requests
import json
import time

# Log into SevOne API.
address = 'http://sevone.com/api/v1/'
creds = {'name': 'user', 'password':'pass'}
r = requests.post( address + "authentication/signin",
                   data=json.dumps( creds ),
                   headers = { 'content-type': 'application/json' })
response = json.loads( r.text )

# Open a session for credential handling.
session = requests.Session()
session.headers.update({ 'content-type': 'application/json',
                         'X-AUTH-TOKEN': response[ 'token' ]})

# Time interval in linux epoch (up to miliseconds).
endTime = int( time.time() * 1000 )
startTime = endTime - 1800000

# Let's get the devices, objects and indicators to collect metrics from them. 
# By default, you'll get the first twenty devices.
r = session.get(address + 'devices')
devices = json.loads(r.text)

for device in devices['content']:
  print "Device: {} id: {}".format( device[ 'name' ], device[ 'id' ])
  r = session.get( address
             + 'devices/{}?includeIndicators=true'.format( device[ 'id' ]))
  response = json.loads(r.text)

  for object in response[ 'objects' ]:
    print "* Object: {} id: {}".format( object[ 'name' ], object[ 'id' ])

    for indicator in object[ 'indicators' ]:
      print "** indictorId: {}".format(
        indicator[ 'id' ])
      indicatorDataUrl = address + "devices/{}/objects/{}/indicators/{}/data".format( 
        indicator[ 'deviceId' ], indicator[ 'objectId' ], indicator[ 'id' ])

      params = { 'startTime': startTime, 'endTime': endTime }
      r = session.get( indicatorDataUrl, params=params )

      print r.url
      print r.text

This was for py27.

Error seems to indicate ca-sevone01 cannot be resolved? I don't know where did that came from.
