Python で Azure の リソースグループ毎に日単位で使用料金 を取得してみました

Posted at

概要

Azure SDK for Python を利用して、特定のサブスクリプションにあるリソースグループ毎に日単位の降順での使用料金を取得表示するための Python プログラムです。

実行環境

macOS Big Sur 11.1
python 3.8.3

実行プログラム

GetSubscriptionCostManagement_11.py
import os
import time
import argparse
from tabulate import tabulate
import itertools
from itertools import groupby
from azure.identity import AzureCliCredential
from azure.mgmt.costmanagement import CostManagementClient

SUBSCRIPTION_ID = os.environ['ARM_SUBSCRIPTION_ID']

# CostManagement情報 を操作するオブジェクトを取得
def GetCostManagementObject():
    costmgmt_client = CostManagementClient(
        credential=AzureCliCredential()
    )
    return costmgmt_client


# 指定した Subscription について CostManagement からコストを取得
def GetCostManagement(costmgmt_client, subs_id):

    # Query costmanagement
    SCOPE = '/subscriptions/{}'.format(subs_id)
    costmanagement = costmgmt_client.query.usage(
        SCOPE,
        {
            "type": "Usage",
            "timeframe": "MonthToDate",
            "dataset": {
                "granularity": "Daily",
                "aggregation": {
                    "totalCost": {
                        "name": "PreTaxCost",
                        "function": "Sum"
                    }
                },
                "grouping": [
                    {
                        "type": "Dimension",
                        "name": "ResourceGroup"
                    }
                ]
            }
        }
    )
    return costmanagement


# サブスクリプションIDを指定しリソースグループ毎に CostManagement情報を取得
def GetSubscriptionCsotManagement():

    # 取得コストの キーと値
    row_key = ['UsageCost', 'CostDate', 'ResourceGroup', 'Currency']
    row_value = []

    # CostManagementを操作するオブジェクトの取得
    costmgmt_client = GetCostManagementObject()

    # 指定のサブスクリプションの CostManagement からコストを取得
    print("\nサブスクリプションID : {}\n".format(SUBSCRIPTION_ID))
    costmanagement = GetCostManagement(costmgmt_client, SUBSCRIPTION_ID)

    # 取得したコスト情報を日付で降順ソートし、辞書型に変換する
    row_value = sorted(costmanagement.rows, key=lambda x:x[1], reverse=True)
    row_dict = [dict(zip(row_key,item)) for item in row_value]
    # print(tabulate(row_dict, headers='keys'))

    # リソースフループでソート
    rows = sorted(row_dict, key=lambda x:x['ResourceGroup'], reverse=False)
    # print(tabulate(rows, headers='keys'))

    # リソースグループでグルーピングする
    for key, resgp in groupby(rows, key=lambda x: x['ResourceGroup']):
        # イテレータを複数回使用するための複製
        resgp_list, resgp_cost = itertools.tee(resgp, 2)

        # 日付降順でのコスト表示
        print("\n リソースグループ : ", key)
        print(tabulate(resgp_list, headers='keys'))

        # このリソースグループでのコスト合計の表示
        TotalCost = sum(costList['UsageCost'] for costList in resgp_cost)
        print("\n\t コスト合計:{0}".format(TotalCost) + " JPY")
    
    costmgmt_client.close()


if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='ある Subscription の コスト取得')
    args = parser.parse_args()

    start = time.time()
    GetSubscriptionCsotManagement()
    generate_time = time.time() - start

    print("\n 取得時間:{0}".format(generate_time) + " [sec] \n")
