matusstafura / magento2-systeminfo
Magento 2 module to show developer system info (PHP/OPcache, MySQL/MariaDB, Redis/Valkey, Elasticsearch/OpenSearch, Varnish, cron, indexers, cache status, disk space) in admin and CLI.
Magento 2 Developer System Info Module
This Magento 2 module provides detailed system information useful for developers, directly in the Admin panel and via CLI.
🔍 Features
- Magento version, edition & mode
- PHP version, extensions & OPcache status (enabled/disabled, hit rate, memory usage)
- Database version — auto-detects MySQL vs MariaDB
- Cache backend version — auto-detects Redis vs Valkey
- Search engine — auto-detects Elasticsearch vs OpenSearch (reads the actual server's
version.distribution, not just what's configured) plus the configured engine - Varnish version (if installed and
shell_execisn't disabled) - Cron health — time since last successful
cron_schedulerun, flagged STALE after 15 minutes - Indexer status — lists any indexer not in a "valid" state
- Magento cache type status — which cache types are enabled/disabled
- Disk free space on the app root
- Operating system info

Compatibility
Each Magento release line is installed on its supported PHP versions, then the module is built (DI compilation + static-content deploy) and its unit and integration suites are run. The matrix shows the lines and PHP versions the module is confirmed to install and run on. Code-quality results further down (phpstan, phpcs, …) are reported separately and never affect compatibility.
Code Quality
Advisory checks against the module's source. Static analysis runs once across the whole module; PHPStan re-runs per Magento + PHP version because resolvable symbols differ between releases. These NEVER affect the Compatibility badge. A phpcs finding can't make a module incompatible.
Static analysis
Coding standards (phpcs), mess detection (phpmd), copy-pasted code (cpd), PHP cross-version compatibility, composer.json validity. Each runs once for the whole module.
PHPStan
Type-checks the module's PHP against a real Magento install at the configured gate level. Re-runs per Magento and PHP version because resolvable symbols differ between releases.
Tests
Unit and integration suites, run for each applicable Magento and PHP version. A test failure speaks to the module's behaviour, not its compatibility with a Magento line, so it is reported here separately and never reddens the compatibility matrix.

| 2.4.9 | N/A | N/A |
Security
Security checks run directly against the module: an audit of its declared dependencies for known vulnerabilities (composer audit) and a scan of its source for malware and web-shell signatures. Each runs once. A malware detection fails the version outright.
