Laravel logging best practice

First of all there are different ways to organize logs.
Personally I like to have daily logs based on interface.

The most important is 'path' => storage_path('logs/laravel-'.php_sapi_name().'.log'), that will use different file for different interface.
Must have if you use any artisan or tinker commands.

So here sample config I use:

Laravel 6+

<?php
//config/logging.php

return [
    //...

    'custom' => [
        'driver' => 'daily',
        'path' => storage_path('logs/laravel-'.php_sapi_name().'.log'),
        'level' => env('LOG_LEVEL', 'debug'),
        // 'days' => env('LOG_DAILY_DAYS', 14),
        'replace_placeholders' => true,
    ],
];

Laravel 5

If you use old laravel that doesn’t have file config/logging.php, then modify bootstrap/app.php

<?php
//bootstrap/app.php
//.....

$app->configureMonologUsing(function(Monolog\Logger $monolog) {
    $filename = storage_path('logs/laravel-'.php_sapi_name().'.log');
    $handler = new Monolog\Handler\RotatingFileHandler($filename);
    $monolog->pushHandler($handler);
});

return $app;

Useful tools for viewing logs

Personally I find useful to have logviewer, just don’t forget to make middleware so only you can view them.
