如何以編程方式訪問Azure功能使用指標？

Question

我想檢索基於消費的Azure函數的粒度GB /秒使用數據。我怎樣才能做到這一點？

Answer 1

使用數據可通過Azure監控REST API獲得。有關如何使用此API的一般概述，請參閱here。

相關度量標準爲FunctionExecutionUnits。這個單位是MB毫秒，所以要將它轉換成GB-seconds，你需要將值除以1,024,000。下面是一個函數應用的例子查詢檢索每分鐘使用量數據：

GET /subscriptions/<subid>/resourcegroups/<rg>/providers/Microsoft.Web/sites/<appname>/providers/microsoft.insights/metrics?api-version=2016-06-01&$filter=(name.value eq 'FunctionExecutionUnits') and timeGrain eq duration'PT1M' and startTime eq 2016-12-10T00:00:00Z and endTime eq 2016-12-10T00:05:00Z and (aggregationType eq 'Total') 

你會得到這樣的事情：

{ 
    "value": [ 
    { 
     "data": [ 
     { 
      "timeStamp": "2016-12-10T00:00:00Z", 
      "total": 0 
     }, 
     { 
      "timeStamp": "2016-12-10T00:01:00Z", 
      "total": 140544 
     }, 
     { 
      "timeStamp": "2016-12-10T00:02:00Z", 
      "total": 0 
     }, 
     { 
      "timeStamp": "2016-12-10T00:03:00Z", 
      "total": 0 
     }, 
     { 
      "timeStamp": "2016-12-10T00:04:00Z", 
      "total": 0 
     } 
     ],  
     "name": { 
     "value": "FunctionExecutionUnits", 
     "localizedValue": "Function Execution Units" 
     }, 
     "type": "Microsoft.Insights/metrics", 
     "unit": "0" 
    } 
    ] 
}
