Windows Azure Trace Log not working

Question

I\'m sure I have missed something simple but I can\'t get simple Trace.WriteLine to work on Azure.

Steps I have taken:

Microsoft.WindowsAzure.Plugins.Diagnostics

I had this same problem. I was using the solution here. I believe the piece you are missing is the location where logs are scheduled to be transferred (in this case, using a LocalResource path):

public override bool OnStart()
{
    Trace.WriteLine("Entering OnStart...");

    var traceResource = RoleEnvironment.GetLocalResource("TraceFiles");
    var config = DiagnosticMonitor.GetDefaultInitialConfiguration();

    // *** this part specifies where transfers should be stored ***
    config.Directories.DataSources.Add(
        new DirectoryConfiguration
        {
            Path = traceResource.RootPath,
            Container = "traces",
            DirectoryQuotaInMB = 100
        });
    config.Directories.ScheduledTransferPeriod = TimeSpan.FromMinutes(10);

    DiagnosticMonitor.Start("DiagnosticsConnectionString", config);

    return base.OnStart();
}  

In order for this to work, you have to create a LocalStorage node to store these files in your ServiceDefinition.csdef:

and you need to have a way to transfer these files to some place where you can get to them, because they are not available in the storage account, but on a local resource folder on the VM itself. I accomplish that with a webpage that allows me to download local resource files.
