Canonical URL: https://packagento.com/matusstafura/magento2-systeminfo

## At a glance

- **Vendor**: matusstafura (https://packagento.com/matusstafura.md)
- **Latest version**: v0.2.0 — released 2026-07-24
- **Pricing**: Free
- **Package type**: Magento 2 module
- **Status**: active, accepting new buyers

## Installation

Packagento is licence-gated, so even free packages need a licence on a project before Composer can resolve them.

1. **Sign in or create an account** at https://packagento.com/customer/account/.

2. **Add the package to your account.** Open https://packagento.com/matusstafura/magento2-systeminfo and complete the free checkout. A licence is minted automatically.

3. **Create or pick a project, then activate the licence on it.**
   - Projects represent the Magento installs you deploy to. Manage them at https://packagento.com/projects/.
   - Activate the new licence on the project you'll deploy this package to. Activation is what generates the Composer credentials scoped to that project.

4. **Add the project credentials to your Magento codebase.**

   Grab the project's public + private key from https://packagento.com/projects/ (open the project, then its Credentials tab), and add them to `auth.json`:

   ```json
   {
     "http-basic": {
       "packagento.com": {
         "username": "ppk_live_...",
         "password": "psk_live_..."
       }
     }
   }
   ```

   Add the Packagento Composer repository to `composer.json`:

   ```json
   {
     "repositories": [
       { "type": "composer", "url": "https://packagento.com" }
     ]
   }
   ```

5. **Install and apply.**

   ```bash
   composer require matusstafura/magento2-systeminfo:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## What it does

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.

## README

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_exec` isn't disabled)
- Cron health — time since last successful `cron_schedule` run, 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

### 📦 Installation

#### 📦 Option 1: Installation via Composer (Packagist)

## Recent Versions

| Version | Released |
|---|---|
| v0.2.0 | 2026-07-24 |
| v0.1.0 | 2025-08-07 |

## Dependencies

### Require

| Package | Constraint |
|---|---|
| magento/framework | >=103.0 |
| php | >=8.1 |

## Quality

Latest release (v0.2.0) fails the Packagento QA pipeline. Verdicts below are per-cell (Magento line × PHP version) for the matrixed tools, and run-once for the static / security tiers.


### Compatibility

Each Magento line is installed on its supported PHP versions, then the module is built (DI compile + static-content deploy). Cells show passed / failed / untested; staircase gaps render as `–`.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | 1 | 1 |


### Code Quality

Advisory checks against the module's source. Never affect the Compatibility verdict — 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.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| PHPCS | Fail | 19 | 6 errors, 13 warnings (ruleset: Magento2), 1 auto-fixable with phpcbf |
| PHPMD | Pass | 0 |  |
| Cpd | Pass | 0 |  |
| Composer validate | Info | 1 | valid; 1 advisory note (composer validate --strict) |

#### PHPStan

Type-checks the module against a real Magento install. Re-runs per Magento + PHP version because resolvable symbols differ between releases.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | 1 | 1 |


### Tests

Unit and integration suites run per Magento + PHP cell. Test failures speak to the module's behaviour, not its compatibility with a line, so they're reported here separately.

#### Unit Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |

#### Integration Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |


### Security

Dependency-advisory audit (composer audit) plus a source malware scan. A malware detection fails the version outright.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| Composer audit | Pass | 0 |  |
| Malware scan | Pass | 0 |  |

## Licence and pricing

Free. A licence is still minted on checkout and bound to your project for Composer access — no payment step.

Refundable within 14 days of first purchase via https://packagento.com/account/refunds/.

## Install via Claude Code or any MCP client

The Packagento MCP server can run the licence + project + Composer steps above in one tool call:

```
purchase_and_install_packages(
  composer_names=["matusstafura/magento2-systeminfo"],
  project_id="proj_xxx"
)
```

This handles cart, checkout, licence minting, project activation, and writes auth.json credentials. Connect a client with `claude mcp add packagento https://mcp.packagento.com`. Full setup at https://packagento.com/docs/mcp-setup.
