Features

• N+1 Query Detection - Automatically detect and report N+1 query patterns
• Slow Query Detection - Identify queries exceeding configurable thresholds with optimization suggestions
• Index Advisor - Get intelligent index recommendations based on query patterns
• Query Explanation - Analyze EXPLAIN plans with efficiency scoring
• Performance Baselines - Create and compare performance baselines across deployments
• Query Budgets - Enforce per-endpoint query limits with configurable actions
• Trend Analysis - Track performance trends over time with visual sparklines
• Real-time Alerts - Get notified about performance issues via Slack, email, or console
• Dashboard - Vue 3 SPA dashboard for visualizing query metrics

Requirements

• PHP 8.3+
• Laravel 11.0+ or 12.0+

Installation

Install the package via composer:

composer require marwen-brini/smart-query-analyzer --dev

Publish and run the migrations:

php artisan vendor:publish --tag="smart-query-analyzer-migrations"
php artisan migrate

Publish the config file:

php artisan vendor:publish --tag="smart-query-analyzer-config"

Usage

Basic Setup

The package automatically starts monitoring queries when enabled. Add the middleware to your routes:

// In app/Http/Kernel.php or bootstrap/app.php
->withMiddleware(function (Middleware $middleware) {
    $middleware->append(\SmartQueryAnalyzer\Http\Middleware\QueryAnalyzerMiddleware::class);
})

Using the Facade

use SmartQueryAnalyzer\Facades\SmartQueryAnalyzer;

// Start listening to queries
SmartQueryAnalyzer::startListening();

// Pause/resume logging
SmartQueryAnalyzer::pause();
SmartQueryAnalyzer::resume();

// Get captured queries and stats
$queries = SmartQueryAnalyzer::getQueries();
$stats = SmartQueryAnalyzer::getStats();

// Flush queries to database
SmartQueryAnalyzer::flush();

Artisan Commands

Analyze Queries

# Analyze queries for a specific request
php artisan query:analyze --request-id=abc123

# Analyze queries for an endpoint
php artisan query:analyze --endpoint=/api/users --method=GET

# Analyze last N requests
php artisan query:analyze --last=10

Slow Queries

# List slow queries
php artisan query:slow

# Custom threshold (ms)
php artisan query:slow --threshold=50

# Filter by endpoint
php artisan query:slow --endpoint=/api/users

# Time window
php artisan query:slow --since="1 hour ago"

Query Explanation

# Explain a query interactively
php artisan query:explain "SELECT * FROM users WHERE email = 'test@example.com'"

# Output formats: table, json, raw
php artisan query:explain "SELECT * FROM users" --format=json

# From file
php artisan query:explain --file=query.sql

Index Recommendations

# Generate index recommendations
php artisan query:indexes

# Detect unused indexes
php artisan query:indexes --unused

# Generate migration file
php artisan query:indexes --migrate

# List pending recommendations
php artisan query:indexes --pending

Performance Baselines

# Create baseline for all endpoints
php artisan query:baseline --create

# Create baseline for specific endpoint
php artisan query:baseline --create --endpoint=/api/users

# List all baselines
php artisan query:baseline --list

# Export baselines to JSON
php artisan query:baseline --export=baselines.json

# Import baselines from JSON
php artisan query:baseline --import=baselines.json

Regression Testing

# Test against baseline
php artisan query:test

# Custom regression threshold (percentage)
php artisan query:test --threshold=20

# Test specific endpoint
php artisan query:test --endpoint=/api/users

# CI mode with minimal output
php artisan query:test --ci

# JSON output
php artisan query:test --json

Compare Performance

# Compare current vs baseline
php artisan query:compare

# Filter by commit/branch
php artisan query:compare --commit=abc123
php artisan query:compare --branch=feature/new

Query Budgets

# Show budget status for all endpoints
php artisan query:budgets

# Show violations only
php artisan query:budgets --violations

# JSON output
php artisan query:budgets --json

Trend Analysis

# Show performance trends
php artisan query:trends

# Custom time period
php artisan query:trends --period=7d

# Interval: hour, day, week
php artisan query:trends --interval=hour

# JSON output
php artisan query:trends --json

Dashboard Management

# Show dashboard status
php artisan query:dashboard

# Enable/disable dashboard
php artisan query:dashboard --enable
php artisan query:dashboard --disable

# Cleanup old logs
php artisan query:dashboard --cleanup
