Filter Support to Custom Queries

[irynamill]

Hi,

I was wondering if there’s a way to apply filters to a custom query in azure-resourcemanager-exporter. Specifically, I’d like to refine the results of a query to include only specific resources based on certain conditions.

queries:
  - name: by_resourceId
    help: Costs by ResourceId
    filter: ???
    dimensions: [SubscriptionId, ResourceGroupName, ResourceType, ChargeType, PublisherType, ResourceId]
    granularity: None
    valueField: PreTaxCost
    timeFrames: [MonthToDate, YearToDate]

When I query the API directly, I am able to add filter in the dataset:

{
  "type": "Usage",
  "timeframe": "MonthToDate",
  "dataset": {
    "granularity": "None",
    "filter": {
      "dimenstions": {
        "name": "ResourceType",
        "operator": "In",
        "values": ["microsoft.storage/storageaccounts"]
      }
    },
    ...
    ...
  }
}

As far as I can see here https://github.com/webdevops/azure-resourcemanager-exporter/blob/main/config/config_cost.go#L18-L32 There is no possibility to add filter as of now? Is there any existing functionality for this that I have missed, or would it be possible to add filter support to custom queries in a future update? If so, could you provide some guidance on how this might be implemented?
