天青流利的API - AppServicePlanOperations.ListMetricsWithHttpMessagesAsync返回InternalServerError

Question

此方法的文档都可以找到here

这里是我的代码：

 var appServiceManager = AppServiceManager.Authenticate(credentials, subscriptionId); 
     var filter = "(name.value eq 'CpuPercentage') and startTime eq '2017-10-06T08:00:00Z' and endTime eq '2017-10-06T09:00:00Z' and timeGrain eq duration'PT1H'"; 
     var metrics = appServiceManager.AppServicePlans.Inner.ListMetricsWithHttpMessagesAsync("myResourceGroupName", "myAppServicePlanName", false, filter).Result;  

这是唯一的详细的异常，我得到：

发生一处或多处错误。 （操作返回无效状态码“InternalServerError”）---> Microsoft.Rest.Azure.CloudException：操作返回了无效的状态代码“InternalServerError”

文档说filter是可选的，它不是（如果我通过null，我会收到BadRequest）。我现在提供一个，现在它会引发内部服务器错误。

我在azure-sdk-for-net回购协议中开了一个问题，但我希望别人能看到我在我的filter字符串中是否犯了错误。

当我使用你提到的代码时，我也可以重现这个问题。我发现另一个Microsoft.Azure.Management.Monitor.Fluent SDK可用于列出资源的度量标准，它是一个测试版版本。我在我身边做了一个演示，它在我身边正常工作。

using Microsoft.Azure.Management.Fluent.ServiceBus; 
using Microsoft.Azure.Management.Fluent.ServiceBus.Models; 
using Microsoft.Rest.Azure.Authentication; 
using Microsoft.Rest.Azure.OData; 

namespace MonitorDemo 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 

      var azureTenantId = "tenant Id"; 
      var azureSecretKey = "secret key"; 
      var azureAppId = "azure AD application Id"; 
      var subscriptionId = "subscription Id"; 
      var resourceGroup = "resource group name"; 
      var servicePlanName = "service plan name"; 
      var serviceCreds = ApplicationTokenProvider.LoginSilentAsync(azureTenantId, azureAppId, azureSecretKey).Result; 
      MonitorClient monitorClient = new MonitorClient(serviceCreds) { SubscriptionId = subscriptionId }; 
      var resourceUri = $"/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Web/serverfarms/{servicePlanName}"; // resource id 
      var metricNames = "name.value eq 'CpuPercentage'"; // could be concatenated with " or name.value eq '<another name>'" ... inside parentheses for more than one name. 

      // The $filter can include time grain, which is optional when metricNames is present. The is forms a conjunction with the list of metric names described above. 
      string timeGrain = " and timeGrain eq duration'PT5M'"; 

      // The $filter can also include a time range for the query; also a conjunction with the list of metrics and/or the time grain. Defaulting to 3 hours before the time of execution for these datetimes 
      string startDate = " and startTime eq 2017-10-06T08:00:00Z"; 
      string endDate = " and endTime eq 2017-10-06T09:00:00Z"; 

      var odataFilterMetrics = new ODataQuery<MetricInner>(
       $"{metricNames}{timeGrain}{startDate}{endDate}"); 

      var metrics = monitorClient.Metrics.ListWithHttpMessagesAsync(resourceUri, odataFilterMetrics).Result; 
     } 
    } 
}
