This is a Vibe Coded Plugin I made with Claude, this Version is not tested yet! I did use the File Based Loggin v1 with SW6.6.10.

SwpMemoryProfiler

Profiles peak memory usage per HTTP request in Shopware 6. Stores data in MySQL, provides admin dashboard with filters, CLI commands, and daily auto-cleanup.

Built to size PHP memory_limit based on real measurements instead of guesses.

Features

• Per-request peak memory + delta + duration logging
• Context separation: Storefront / API / Admin
• Admin dashboard under Settings → System → Memory Profiler with filters (context, time range, route, status code, min peak)
• CLI: bin/console swp:memory:report and swp:memory:clear
• Daily scheduled task for auto-cleanup (default: 30 days retention)
• Failsafe: DB errors never crash the request

Requirements

• Shopware 6.6.x
• PHP 8.3+
• MariaDB 10.4+ / MySQL 8.0+

Installation

cd custom/plugins/
unzip SwpMemoryProfiler.zip

cd ../..
php bin/console plugin:refresh
php bin/console plugin:install --activate SwpMemoryProfiler
php bin/console database:migrate --all SwpMemoryProfiler
./bin/build-administration.sh
php bin/console cache:clear

Configuration

Edit src/Resources/config/services.xml:

<parameter key="swp_memory_profiler.enabled">true</parameter>
<parameter key="swp_memory_profiler.retention_days">30</parameter>

Set enabled=false to stop logging while keeping data and admin UI accessible. Roadmap item: move to admin config UI.

Usage

Admin UI: Login → Settings → System → Memory Profiler

CLI:

# Top 20 entries of last 24 hours
php bin/console swp:memory:report --hours=24

# Storefront only, last week, top 50
php bin/console swp:memory:report --context=STORE --hours=168 --limit=50

# Cleanup
php bin/console swp:memory:clear --older-than=7
php bin/console swp:memory:clear --force        # nukes everything

Performance

~1–3 ms overhead per request (single DBAL INSERT). At ~50 req/sec the load is negligible. For high-traffic shops (>500 req/sec sustained) consider disabling between profiling sessions.

Recommended workflow: enable for 48h to capture realistic peaks under load, analyze in admin, disable, adjust memory_limit in php-fpm pool / php.ini cli.

Development

See CLAUDE.md for architecture details and conventions.
