CloudException: Internal Server Error when Using ListMetricsAsync Method

[AMoghrabi]

I'm using Microsoft.Azure.Management.AppService.Fluent to collect information about my App Service Plans. The method I'm using is ListMetricsAsync.

My first problem is, the documentation says that the filter argument is optional. This is incorrect as the underlying web API throws an exception:

Microsoft.Rest.Azure.CloudException : Operation returned an invalid status code 'BadRequest'
Inner Exception: <Error xmlns:i="http://www.w3.org/2001/XMLSchema-instance\" xmlns="http://schemas.microsoft.com/windowsazure\">InvalidFilterValueParameterArgument Null\r\nParameter name: $filter

I've tried supplying an empty string but that does not work.

It looks like I must supply a filter so I try that... However, supplying a filter seems to return Microsoft.Rest.Azure.CloudException : Operation returned an invalid status code 'InternalServerError'
Here is my code:

    var appServiceManager = AppServiceManager.Authenticate(credentials, subscriptionId);
    var filter = "(name.value eq 'CpuPercentage') and aggregationType eq 'Average' and timeGrain eq duration'PT1H' and startTime eq 2017-10-06T19:00:00Z and endTime eq 2017-10-06T20:00:00Z";
    var metrics = appServiceManager.AppServicePlans.Inner.ListMetricsAsync("MyResourceGroupName", "MyAppServiceName", null, filter).Result;

I assume that my filter has incorrect syntax. Can you please advise what I need to do to get this working?

Thanks!

@shahabhijeet this is not Fluent specific. @AMoghrabi was using Inner to make a call which means that it was auto generated code. This needs to be investigated with the AppService team.

Is there a different way to access that method without using inner?

[AMoghrabi]

Also, should I open my issue on a different repository?

I am experiencing the same issue. Any update?
