function azure logging azure-functions

I'm relatively new to Azure and I just went through the tutorial on how to create a new Azure function, which is triggered when a new blob is created, and had this as the default code in it.

public static void Run(Stream myBlob, string name, TraceWriter log)
{
    log.Info($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
}

From what I can see on the tutorial, I should be able to see some information in the "logs" area below the code, but nothing shows up, I've been checking for a solution for a while now but can't seem to find anything useful.

Any help would be greatly appreciated.

The log window is a bit fragile and doesn't always show the logs. However, logs are also written to the log files.

You can access these logs from the Kudu console: https://[your-function-app].scm.azurewebsites.net/

From the menu, select Debug console > CMD

On the list of files, go into LogFiles > Application > Functions > Function > [Name of your function]

There you will see a list of log files.
