Introduction

Health Checker for Joomla is a comprehensive monitoring extension that helps you maintain a healthy Joomla website by running automated checks across multiple categories.

What Does It Do?

Health Checker examines your Joomla site and reports on:

• System & Hosting - PHP configuration, required extensions, disk space, scheduler health
• Database - Connection health, table status, character encoding
• Security - File permissions, security headers, authentication settings
• Users - Admin account security, inactive users, session settings
• Extensions - Updates available, compatibility issues, template overrides
• Performance - Caching configuration, compression, OPcache status
• SEO - Meta descriptions, URL structure, broken links
• Content Quality - Orphaned articles, broken menu items, empty categories

How It Works

Health Checker is not a monitoring service. It doesn't run in the background or send alerts. Instead:

1. You visit the Health Checker page in your Joomla admin panel
2. Click "Run Health Check" to execute all checks
3. View the results immediately - Critical, Warning, or Good status for each check
4. Take action on any issues identified
5. Export reports if needed (JSON or HTML format)

Results are not stored - each time you run the health check, you get fresh results based on the current state of your site.

Who Should Use It?

• Identify security vulnerabilities before they're exploited
• Catch configuration problems early

Developers & Agencies

• Pre-launch site audits

• Troubleshooting configuration issues
• Quality assurance checks

Hosting Providers

• Verify server configuration meets Joomla requirements
• Identify customer sites with issues
• Generate health reports for support tickets

What Health Checker Doesn't Do

• No Background Monitoring - Checks only run when you click the button
• No Email Alerts - Results are displayed in the admin panel only
