Enabling Data Storage

Enabling Bill Subscription

1. Create a bucket on OBS. For details about how to create a bucket, see Creating a Bucket.
2. Log in to the Billing Center.
3. Go to the Expenditure Data Storage page.
4. Set the bucket name.
   

   If the bucket becomes invalid, expenditure data storage is automatically disabled.

5. Click Verify.

   A message indicating that the verification is successful is displayed and all eligible bills are presented.

6. Select the bills that you want to export and click Enable.

   Once authorized and verified, the files for your selected bills will be synchronized to your bucket on OBS every day.

   • Set Push

     If you select the check box, the expenditure data updated upon bill adjustments will be synchronized to your bucket on OBS.

   • Save Bills of Unified Accounting Members

     This field is available only to the master account with unified accounting.

     When this field is set to Yes, Huawei Cloud pushes bills of member accounts to the master account for unified accounting. If this field is set to No, Huawei Cloud does not push bills of member accounts to the master account.

7. Click Get Code.
8. Enter the received SMS verification code and click OK.
   

   You can click Close next to the object storage name to close expenditure data storage.

Downloading Subscribed Bills

1. Choose Service List > Storage > Object Storage Service.
2. Click the bucket name.

   

3. In the navigation bar on the left, click Objects. You can view all files of the subscribed bills that have been exported.
   

   • Bills of the same type are sorted in descending order.
   • You can search for bills by bill name prefix. Example: Enter Spendings(ByResource)_201906 in the search box to view all resource bill files in June 2019.
   • Data generated each day for customers in the monthly settlement mode is estimated. It is suggested that these customers obtain the full bill of a month on the third day of the next month.

   After expenditure data storage is enabled, data listed in Table 1 will be automatically exported based on your selection.

   Table 1 Exported bills

   Bill	Billing Period	Data to Be Exported	Filename Identifier
   Resource Expenditures	Every day	Resource expenditure data of the previous day	Resource_Expenditures_YYYYMMDD
   	Third day of each month	Pay-per-use expenditure data of the last month (for example, data of CDN expenditure charged based on daily average peak bandwidth). NOTE: Such data is not displayed if there is no monthly-settled pay-per-use products.	Resource_Expenditures(Pay-per-Use)_MonthlyBill_YYYYMM
   Resource Bill	Every day	Current month (excluding the current day)	Spendings (ByResource)_YYYYMMDD
   	Third day of each month	Last month (YYYYMMDD in the file name indicates the last day of the last month)	Spendings (ByResource)_YYYYMMDD

4. Select the bill you want to download and click Download in the Operation column.

Further Description

If you want to download subscribed bills every day, run the following script to set it up. After the setup is completed, the subscribed bills will be automatically downloaded.

The following code example is for reference only. You can make changes to it for development as needed.

#!/usr/bin/python
# -*- coding:utf-8 -*-
import string,os,sys,datetime
import commands
import json

#get date 
date = datetime.date.today()-datetime.timedelta(1)
str_date = date.strftime("%Y%m%d")

AK = ''
SK = ''
server = ''
bucketName = ''
#prefix="Consumedetails_"+str_date
prefix="Resource_Expenditures_"+str_date
print prefix

from com.obs.client.obs_client import ObsClient
# Constructs a obs client instance with your account for accessing OBS
obsClient = ObsClient(access_key_id=AK, secret_access_key=SK, server=server)

#find which billing
resp=obsClient.listObjects(bucketName,prefix)
#billing name
objectKey=resp.body.contents[0].key
localFileDir='/opt/huawei/zcm/data/'+objectKey
# Download the object to a file
print('Downloading an object to dir:' + localFileDir + '\n')
obsClient.getObject(bucketName, objectKey, downloadPath=localFileDir)

Description of parameters:

• AK: access key ID on OBS. One AK maps to only one user but one user can have multiple AKs. The OBS system recognizes the users who access the system by their access key IDs. For details about how to obtain the AK and SK, see Obtaining Access Keys (AK and SK).
• SK: secret access key on OBS. It is used to access OBS. Authentication information is generated for users based on their SKs and request header fields. An SK matches an AK.
• server: domain name, which is the address of the bucket on the Internet. It can be used for scenarios where the bucket is accessed directly through the domain name, such as cloud application development and data sharing. You can obtain its value from "1" in Figure 1.
• bucketName: name of the bucket used for the subscribed bills. You can obtain its value from "2" in Figure 1.
• prefix: bills that need to be automatically downloaded.
  • "Resource_Expenditures_": Indicates resource expenditure records.
  • "Spendings (ByResource)_": Indicates the resource bill.
• localFileDir: local directory for storing downloaded bill files.
