Laravel: change log path to include user folder - laravel

Question

I use Laravel 5.1 and I am trying to intercept the default logger configuration (Monolog) and save logs to a different path that includes user name.
The current logs are saved to storage/logs/laravel.log.
The wanted paths are as follows
Authenticated Users: storage/logs/[username]/[date]_[api_path].log
Other user logs can be saved under storage/logs/guest/[date]_[api_path].log
ServiceProvider Approach
Have a LogServiceProvider and where I can modify each request and set the path as wanted.
public function boot(Request $request)
{
$log = new Logger('View Logs');
$user = \Auth::User()->getName(); // ERROR - uninitialized
$path = 'storage/logs/'.$user.'/mylogfile.log'; // doesn't matter API path
$log ->pushHandler(new StreamHandler($path, Logger::INFO));
...
}
The problem with this approach, the Auth::user() seems to be uninitialized.
Why does this happen and how do I solve this?

Answer 1

You might need to wrap it in an if statement, such as:
if ( Auth::check() ) {
// Do auth stuff
}
else {
// Do unauth stuff
}
Does that solve your problem?

Answer 2

This is because Auth has not been initialized and it is too early to call.
There is example way to solve:
Create log initializer, and call it from middleware (or from wherever you want):
class UserLogger
{
public function init()
{
$logger = new Logger('order');
$currUserId = Auth::id();
$logPath = storage_path('logs/by_user/' . $currUserId . '/' . Carbon::now()->toDateString() . '.log');
$logger->pushHandler(new StreamHandler($logPath, Logger::INFO));
return $logger;
}
}
//app\Http\Middleware\Authenticate.php
class Authenticate
{
public function handle($request, Closure $next, $guard = null)
{
$userLogger = new UserLogger();
$logger = $userLogger->init();
$context = ['some context data' => 'data'];
$logger->info('custom user actions', $context);
//...
