Azure Fluent API - AppServicePlanOperations.ListMetricsWithHttpMessagesAsync Returns InternalServerError

Question

可以找到此方法的文档 here

这是我的代码：

        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;    

这是我得到的唯一详细异常：

One or more errors occurred. (Operation returned an invalid status code 'InternalServerError') ---> Microsoft.Rest.Azure.CloudException: Operation returned an invalid status code 'InternalServerError'

文档说 filter 是可选的，但事实并非如此（如果我传入 null，我会收到 BadRequest）。我现在提供一个，现在它抛出一个内部服务器错误。

我已经在 azure-sdk-for-net 回购上提出了一个问题，但我希望其他人可以看看我的 filter 字符串是否有任何错误。

我也可以在使用您提到的代码时在我这边重现这个问题。我发现另一个 Microsoft.Azure.Management.Monitor.Fluent SDK 可用于列出资源的指标，它是 beta 版本。我自己做了一个demo，在我这边运行正常。

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;
        }
    }
}
