Laravel 5.3 - How to log all queries on a page?

Question

My team and I are working on a rather big project. There\'s queries going on everywhere - in controllers, in view composers in views (lazy loading) and probably in some othe

Answer 1

add a middleware that executes after the request is done and logs your queries ... see Terminable Middlwares

Answer 2

If you want to print a query which is executed on your app do following steps.

Step1: Go to your AppServiceProvider.php file. // File path App\Providers\AppServiceProvider.php

Step2: Make boot() method and paste below code.

public function boot() {
        // Log queries
        if (true) {
            \DB::listen(function ($query) {
                \Log::info(
                    $query->sql, $query->bindings, $query->time
                );
            });
        }
    }

Step3: Now you can see you queries in lumen.log or laravel.log file. File path is laravel_app\storage\logs\laravel.log or lumen.log.

Enjoy....

Answer 3

You can add this to the Providers/AppServiceProvider.php file and check them in the laravel log file with tail:

tail -f storage/logs/laravel.log

You can even filter with queries you want to log. For example, here I was using Laravel Passport, and didn't want to log all the oauth queries.

use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Event;
use Illuminate\Support\Facades\Log;

public function register() {
    if (App::environment('local') && env('APP_URL') == 'http://localhost') {
        Event::listen('Illuminate\Database\Events\QueryExecuted', function ($query) {
            // filter oauth ones
            if (!str_contains($query->sql, 'oauth')) {
                Log::debug($query->sql . ' - ' . serialize($query->bindings));
            }
        });
    }
}

Answer 4

Are you using MySQL? You can just tail the log.

How to show the last queries executed on MySQL?

Or use the Laravel Debug Bar?

Answer 5

Here comes the perfect example:

https://laravel.com/docs/5.3/database#listening-for-query-events

Open app\Providers\AppServiceProvider.php and add the following to Boot() function:

DB::listen(function ($query) {
    var_dump([
        $query->sql,
        $query->bindings,
        $query->time
    ]);
});

Answer 6

Additioanlly There's package available also:

log-my-queries

https://packagist.org/packages/technoknol/log-my-queries

Just install and add it's entry to middleware. It will log all the queries in laravel.log default log file.
