🔍 Filter by log level (error, info, debug, etc.), by channel, date range or log content inclusion or exclusion,
🔍 Search multiple log files at once,
🌑 Dark mode,
🖥️ Multiple host support,
💾 Download or delete log files from the UI,
☎️ API access for folders, files & log entries,

Getting started

Requirements

PHP 8.1+
Symfony 6.0+ or 7.0+

Installation

Use composer.

composer require fdekker/log-viewer-bundle

If you don't use Symfony Flex, you'll need to manually enable the bundle:

# /config/bundles.php
return [
    // ...
    FD\LogViewer\FDLogViewerBundle::class => ['all' => true],
];

And add the route by creating file /config/routes/fd_log_viewer.php:

<?php
use Symfony\Component\Routing\Loader\Configurator\RoutingConfigurator;

return static function (RoutingConfigurator $routingConfigurator): void {
    $routingConfigurator->import('.', 'fd_symfony_log_viewer')->prefix('/log-viewer');
};

⚠ Ensure access to your logs are secure by adding the line below to /config/packages/security.php:

return static function (SecurityConfig $security): void {
    ...
    $security->accessControl()->path('^/log-viewer')->roles(['ROLE_ADMIN']);
};

After installing the package, publish the front-end assets by running:

php bin/console assets:install

Usage

Once the installation is complete, you will be able to access Log Viewer directly in your browser.

By default, it is available at: /log-viewer on your domain.
