README

A debugging and observability package for Laravel applications. Probe records requests, exceptions, queries, jobs, cache operations, and scheduled tasks — then surfaces them in a real-time dashboard.

Dashboard screenshot — coming soon

Requirements

PHP 8.2+
Laravel 10, 11, or 12

Installation

composer require morcen/probe

Run the install command to publish the config and migrate:

php artisan probe:install

Or publish assets manually:

php artisan vendor:publish --tag=probe-config
php artisan vendor:publish --tag=probe-migrations
php artisan migrate

Dashboard Access

Visit /probe in your browser. By default, access is restricted to local environments. To customize authorization, add the following to your AppServiceProvider:

use Morcen\Probe\Probe;

Probe::auth(function ($request) {
    return $request->user()?->isAdmin();
});

You can change the dashboard path via the PROBE_PATH env variable or the config file.

Watchers

Probe ships with six watchers. Toggle them in config/probe.php or via environment variables:

Watcher	Env Variable	Default
Requests	`PROBE_WATCHER_REQUESTS`	`true`
Exceptions	`PROBE_WATCHER_EXCEPTIONS`	`true`
Jobs	`PROBE_WATCHER_JOBS`	`true`
Queries	`PROBE_WATCHER_QUERIES`	`true`
Cache	`PROBE_WATCHER_CACHE`	`false`
Schedule	`PROBE_WATCHER_SCHEDULE`	`true`

Query intelligence

The query watcher automatically tags slow queries and detects N+1 patterns:

PROBE_SLOW_QUERY_MS=100   # queries over this threshold are tagged "slow"
PROBE_N1_THRESHOLD=5      # same query fingerprint N times = tagged "n1"

Alerts

Probe fires notifications when entries match a rule. Configure rules in config/probe.php:

'alerts' => [
    ['types' => ['exceptions'], 'channel' => 'slack', 'url' => env('PROBE_SLACK_WEBHOOK')],
    ['types' => ['jobs'], 'tags' => ['failed'], 'channel' => 'webhook', 'url' => env('PROBE_WEBHOOK_URL')],
    ['types' => ['queries'], 'tags' => ['slow'], 'channel' => 'log'],
],

Supported channels: slack, webhook, log.

Pruning

Schedule the prune command to keep your database clean:

// routes/console.php
Schedule::command('probe:prune')->daily();

Pruning TTLs are configurable per entry type:

PROBE_PRUNE_REQUESTS=7
PROBE_PRUNE_EXCEPTIONS=30
PROBE_PRUNE_JOBS=7
PROBE_PRUNE_QUERIES=3
PROBE_PRUNE_CACHE=1
PROBE_PRUNE_SCHEDULE=7

To clear all entries immediately:

php artisan probe:clear

Sampling

For high-traffic production environments, record a fraction of entries:

PROBE_SAMPLING_RATE=0.1  # record 10% of entries

Laravel Octane

Probe supports Laravel Octane. Per-request state resets automatically between requests.

Configuration Reference

Publish and review config/probe.php for all options. Key environment variables:

Variable	Default	Description
`PROBE_ENABLED`	`true`	Enable or disable Probe entirely
`PROBE_PATH`	`probe`	Dashboard URI path
`PROBE_STORAGE_DRIVER`	`database`	Storage backend
`PROBE_SAMPLING_RATE`	`1.0`	Fraction of entries to record
