Handling Tenant Resource Utilization Data

Applies To: Windows Azure Pack

The Usage Service REST API provides access to tenant resource utilization data through the Retrieve Usage Data for Tenant Resources REST call. The data is returned in an array of UsageRecord (Usage Metering Object) objects mapping to the provider that the data is from. The provider specific data is stored in the Resources property as a dictionary of name value pairs.

Getting Tenant Resource Utilization Data

The Usage Service REST API exposes resource utilization data via a call to the Retrieve Usage Data for Tenant Resources REST operation. For example:

https://<Computer>:30022/usage?startId=0&batchSize=1 HTTP/1.1
Accept: application/json
Authorization: basic <Token>
Host: <Computer>:30022
Connection: Keep-Alive

Note

startId is the record id of the first record you want to fetch in a particular cycle.
batchSize is the maximum number of records you want to fetch.
<computer> is the Admin API computer name.
30022 is the port designated for the Usage Service.

The response body returns a list of UsageRecord (Usage Metering Object) objects. For example:

[
  {
    "EventId": 1,
    "ExternalRecordId": "1",
    "ResourceId": null,
    "StartTime": "2013-07-31T17:15:49",
    "EndTime": "2013-07-31T17:17:42",
    "ProviderName": "mysqlservers",
    "ServiceType": "Default",
    "SubscriptionId": "a7319215-d5f8-483e-813c-44119bc4ca79",
    "Properties": null,
    "Resources": {
      "TotalAllottedSpace": "1024",
      "DatabaseCount": "1"
    }
  }
]

Function GetAllUsageRecords in the RestApiConsumer.cs file in the ContosoHelp sample demonstrates how to retrieve usage data.

Processing Tenant Resource Utilization Data

A billing Adaptor needs to process usage data from four providers; Websites, SQL Server, MySQL Server, and the System Center Virtual Machine Clouds.

Note

Virtual machine usage metrics are aggregated at a per hour granularity.
