Azure DiagnosticsMonitorTraceListener not working

Azure is starting to do my nut, I am trying to get diagnostics tracing working and have followed various guides (all pretty much say the same thing). I now can't debug locally (I get errors) and RDP doesn't seem to want to connect. I have the following in the web config:

 <system.diagnostics>
<trace>
  <listeners>
    <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">
      <filter type="" />
    </add>
  </listeners>
</trace>

And then this in the webrole.cs:

public override bool OnStart()
    {
        var diagnostics = DiagnosticMonitor.GetDefaultInitialConfiguration();

        diagnostics.Logs.ScheduledTransferLogLevelFilter = LogLevel.Undefined;
        diagnostics.Logs.ScheduledTransferPeriod = TimeSpan.FromMinutes(1);
        diagnostics.Logs.BufferQuotaInMB = 10;

        CloudStorageAccount account = CloudStorageAccount.Parse(
            RoleEnvironment.GetConfigurationSettingValue("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString"));

        DiagnosticMonitor.Start(account, diagnostics);

        return base.OnStart();
    }

And this in the service definition file:

<Imports>
  <Import moduleName="Diagnostics" />
  <Import moduleName="RemoteAccess" />
</Imports>

And this in the service config file:

<ConfigurationSettings>
  <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="DefaultEndpointsProtocol=https;AccountName=<snip>;AccountKey=<snip>" />

I don't get any errors when the site is deployed, I tried a text listener locally which worked fine but I get nothing in table storage on Azure. This has worked before but I have since moved the deployment to another subscription and storage account. Because of my RDP problems, I can't even see if various files are created locally on the instance and I don't know what files to check for anyway!

Please help!

I finally managed to get it working by following this guide: Here

Basically the only difference was in the OnStart method of my web role and rather than the code above which is found in almost all of the examples online, I had to use the following, perhaps because I am using multiple instances?

public override bool OnStart()
    {
        string wadConnectionString = "Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString";
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue(wadConnectionString));

        RoleInstanceDiagnosticManager roleInstanceDiagnosticManager = storageAccount.CreateRoleInstanceDiagnosticManager(RoleEnvironment.DeploymentId, RoleEnvironment.CurrentRoleInstance.Role.Name, RoleEnvironment.CurrentRoleInstance.Id);
        DiagnosticMonitorConfiguration config = DiagnosticMonitor.GetDefaultInitialConfiguration();

        config.Logs.ScheduledTransferPeriod = TimeSpan.FromMinutes(1D);
        config.Logs.ScheduledTransferLogLevelFilter = LogLevel.Undefined;

        roleInstanceDiagnosticManager.SetCurrentConfiguration(config);
        return base.OnStart();
    }

Thank you elastacloud!
