Show azure cost analysis data using Azure billing

问题:

In Azure portal ,if one subscription is selected ,the cost analysis can be viewed like the following screenshot

I want to programmatically fetch the information the like the one displayed above may be using using some python SDK API/REST API. If anybody has any experience/idea on this ,please help.

After going through replies ,I have gone through the Azure Billing Rest API and I am now able to call the Usage Aggrgate and RateCard related Rest APIs.

Following are the results of those REST Calls. .Azure Billing Usage Aggregate Response

Azure Billing Ratecard Response

But honestly speaking ,I still have not figured out how these to would give me detailed view like the cost analysis does where for each resource how much cost associated can be displayed.Actually I am very new to Azure probably that is why I am missing the link some where .

Can somebody give some hint here ?

If you already have the usage and the ratecard data, then you must combine them. Take the meterId of the usage data and get the related ratecard data. The ratecard data contains the MeterRates and the IncludedQuantity which you must take. There are probably multiple meter rates and the included quantity because there are probably different costs per usage (e.g. first 10 calls for free, 3 GB for free, ...). The consumption starts/is reseted at the 14th of the month. That's the reason why you have to read the data from the whole billing period (begins with 14th of each month), because that's the only way how you get the correct consumption.

So, if you are using e.g. Azure Functions and you have a usage of 100.000 units per day and you want the costs from 20th - 30th, then the calculation works as follows: read data from 14th - 30th. These are 17 days and therefore it used 1.700.000 units. The first 400.000 are for free = IncludedQuantity (so in this sample the first 4 days). From the 400.001 unit on, you have to take the meter rate (0,0000134928 €) and calculate the costs. 1.300.000 * 0,0000134928 = ~17,54€. Fortunately, the azure functions have only one rate. If the rate changes e.g. after 5.000.000 units, then you also have to take this into account. If you have the whole costs, then you can filter on your date which is 20.-30. and you will get the result.

That's the short explanation of the calculation. I implemented this calculation in C# and published it as a NuGet package. The source code is on github - probably it helps. It also contains a sample console which you could use to export the data.

There are the offical documents below for retrieving the billing data using Python SDK or REST API in Python.

1. For using Python SDK, please see http://azure-sdk-for-python.readthedocs.io/en/latest/resourcemanagementcommerce.html.
2. For using Billing REST API, please see https://docs.microsoft.com/en-us/rest/api/billing/, and you can try to use Python package requests to get these data.

However, I think you may have know these above, the key is that you need to follow the tutorial Manage access to billing information for Azure using role-based access control to get the role permission via your account admin.

And then you may also need to register a client app to get the client id for Resource Management Authentication if you want to use Service Principal/ADAL (not AD User/Password) in Python SDK or use REST API to do the same authentication as Azure REST API Reference page said. For the authentication topic, you can refer to the content map of Manage Apps to know more if you have been getting some trouble.

Hope it helps. Any concern, please feel free to let me know.
