Usage Reporting for Pay-as-you-go Items

Updated: June 30, 2021
Contents

Overview

Enable the Pay-As-You-Go capability to implement the corresponding system and report subscription usage data to your Providers via the CloudBlue Connect platform.

The following instructions showcase how to configure the Processor and implement the QT (quantity schema) usage reporting for your specified pay-as-you-go (PAYG) items. The quantity schema enables Vendors to report quantity of consumed items. In general, Vendors generate these usage reports and submit them to Providers via the Usage module of the Connect platform once a month. However, Vendors can also deploy the Processor to generate such reports from their systems.

The Vendors API allows generating the QT-based usage reports that includes configured PAYG items. Therefore, the Processor can provide monthly reports for each of your products and for each of your distribution contracts. Furthermore, the Processor can submit these reports for corresponding Providers.

Prerequisites

Before following the provided use case, make sure that all of these prerequisites are met:

Usage Report Files

Usage report files generated via the Processor will be stored within the Usage management module of the Connect platform. This module allows submitting usage report files to Providers. Once a Provider receives a generated usage report file, this Provider can accept or reject it. Follow the instructions below to enable usage report files creation on the CloudBlue Connect platform.

Edit Capabilities

Before generating a usage report file, make sure that the Pay-as-you-go capability and your selected reporting schema are enabled.

Proceed to the Capability tab from the General section of your product profile page. Thereafter, click the Edit button to switch on required capability and reporting schema.

Note that the QT reporting schema should be enabled.

Pay-as-you-go Items

Next, this scenario requires to create and configure PAYG items.

Proceed to the Items section from your product profile page and switch to the Pay As You Go tab.

Thereafter, click the Create Item button to specify your PAYG items on the Connect platform.

Integer Precision

The quantity reporting schema is usually requires the Integer precision during the PAYG items creation.

Refer for the Pay-as-you-go Items documentation for more details.

Select a Subscription

Once your PAYG items are successfully specified, select a subscription that was in the Active state last month and that allows fetching quantity data via Vendor API.

Learn more about usage report files and their creation process on the CloudBlue Connect platform from to the Usage management module documentation.

Code Snippet

Create a script that generates and fills out usage report files via the Vendor API calls.

class Usage:
def __init__(self, client: ConnectClient):
self.client = client
# This method loads contracts and subscriptions to create and fill out a usage report file.
def process_usage(self):
usage_data = Usage._get_usage_records()
# Customize the Vendor API response.
if Usage._count_usage_records(usage_data) == 0:
# In case there is no data to report.
return
contracts = self._get_contracts()
counter = 0
# The following provides usage data for each contract.
for contract in contracts:
counter += self._report_contract_usage(contract, usage_data)
if counter != Usage._count_usage_records(usage_data):
# In case not all subscriptions with data included in your report.
raise ValueError()
def _report_contract_usage(self, contract, usage_data):
# The following filters the subscriptions with the usage data.
# For the preview environment, all the subscription belongs to contract CRD-00000-00000-00000
subscriptions = self._get_subscriptions(contract, self._get_subscription_filter(usage_data))
product_id = None
record_data = []
counter = 0
# Locates the subscriptions with usage data for each contract.
# It is necessary to create a Usage instance for each product.
for subscription in subscriptions:
counter = counter + 1
if product_id is None:
product_id = subscription['product']['id']
self._validate_ppu_schema(product_id)
if product_id != subscription['product']['id']:
self._create_usage(contract, product_id, record_data)
product_id = subscription['product']['id']
self._validate_ppu_schema(product_id)
record_data.clear()
else:
# The following fills the records with subscription usage data.
record_data.append(Usage._get_usage_data(subscription, usage_data))
if product_id is not None:
self._create_usage(contract, product_id, record_data)
return counter
def _get_contracts(self):
# The following loads distribution contracts to find subscriptions with data and generate reports.
query = R()

return contracts
def _get_subscriptions(self, contract, subs_id_filter):
query = R()
query &= R().contract.id.oneof([contract['id']])
query &= R().id.oneof([subs_id_filter])

self._upload_usage(usage_file_id, usage_excel_path)
# Submit this file to your Provider.
self._submit_usage(usage_file_id)
# The following generates monthly reports on the platform for a particular contract and product.
def _create_usage_file(self, contract, product_id):
# Type: (Any, str) -> str
# The report file ID uses the following format: UF-yyyy-mm-####-####
contract_id = contract['id']
currency = self.client.collection('marketplaces')[contract['marketplace']['id']].get()['currency']
date_to = datetime(datetime.today().year, month=datetime.today().month - 1,
day=monthrange(datetime.today().year, datetime.today().month - 1)[1])
date_from = datetime(datetime.today().year, month=datetime.today().month - 1, day=1)
name = date_from.strftime("%d-%m-%Y") + " - " + date_to.strftime("%d-%m-%Y")

"to": date_to.strftime("%Y-%m-%d")
},
"currency": currency,
"product": {
"id": product_id
},
"contract": {
"id": contract_id
},
"external_id": external_file_id
}
file = self.client.ns('usage').files.create(payload=payload)
return file['id']
def _upload_usage(self, usage_file_id, usage_file_path):
# Type: (str, str) -> None
# Uploads a generated Excel file to the Connect platform.
file_data = open(usage_file_path, 'rb').read()
file_name = ntpath.basename(usage_file_path)
payload = {
"usage_file": (file_name, file_data)
}
self.client.ns('usage').files[usage_file_id].action('upload').post(files=payload)
# The following submits the usage report to Providers.
def _submit_usage(self, usage_file_id):
# Type: (str) -> None
self.client.ns('usage').files[usage_file_id].action('submit').post()

Summary

As a result, a usage report file is generated for each product and each distribution contract. Note that the system will submit your generated usage report file to your Provider and will assign the Pending status to this report.
