Azure Cost Management API does not allow me to select columns - json

Question

I tried to use the Azure Cost Management - Query Usage API to get details (certain columns) on all costs for a given subscription. The body I use for the request is
{
"type": "Usage",
"timeframe": " BillingMonthToDate ",
"dataset": {
"granularity": "Daily",
"configuration": {
"columns": [
"MeterCategory",
"CostInBillingCurrency",
"ResourceGroup"
]
}
}
But the response I get back is this:
{
"id": "xxxx",
"name": "xxxx",
"type": "Microsoft.CostManagement/query",
"location": null,
"sku": null,
"eTag": null,
"properties": {
"nextLink": null,
"columns": [
{
"name": "UsageDate",
"type": "Number"
},
{
"name": "Currency",
"type": "String"
} ],
"rows": [
[
20201101,
"EUR"
],
[
20201102,
"EUR"
],
[
20201103,
"EUR"
],
...
]
}
The JSON continues listing all the dates with the currency.
When I use the dataset.aggregation or dataset.grouping clauses in the JSON, I do get costs returned in my JSON but then I don't get the detailed column information that I want. And of course it is not possible to combine these 2 clauses with the dataset.columns clause. Anyone have any idea what I'm doing wrong?

Answer 1

I found a solution without using the dataset.columns clause (which might just be a faulty clause?). By grouping the data according tot the columns I want, I can also get the data for those column values:
{
"type": "Usage",
"timeframe": "BillingMonthToDate",
"dataset": {
"granularity": "Daily",
"aggregation": {
"totalCost": {
"name": "PreTaxCost",
"function": "Sum"
}
},
"grouping": [
{
"type": "Dimension",
"name": "SubscriptionName"
},
{
"type": "Dimension",
"name": "ResourceGroupName"
}
,
{
"type": "Dimension",
"name": "meterSubCategory"
}
,
{
"type": "Dimension",
"name": "MeterCategory"
}
]
}
