Maintenance Checklists

Maintenance Checklists

Maintenance checklists are essential tools for ensuring the long-term health, security, and performance of any wiki, particularly those built with MediaWiki. They provide a structured approach to regular tasks, preventing issues from escalating and ensuring a positive user experience. This article provides a comprehensive guide to creating and implementing effective maintenance checklists for your MediaWiki installation, geared towards beginners. We will cover various aspects, from routine tasks to more complex procedures, categorizing them for clarity and ease of use.

Why Use Maintenance Checklists?

Without a proactive maintenance plan, a wiki can suffer from several problems:

Performance Degradation: Over time, database bloat, inefficient code, and accumulated temporary files can slow down the wiki, frustrating users. Regular database optimization and cleanup are crucial. See Database administration for more details.
Security Vulnerabilities: Outdated software, extensions, and weak passwords create opportunities for malicious attacks. Keeping everything up-to-date and enforcing strong security practices are paramount. Learn more about Security on MediaWiki.
Data Loss: Without regular backups, a server crash or security breach can result in the loss of valuable wiki content. A robust backup strategy is non-negotiable.
Broken Functionality: Extensions may become incompatible with newer MediaWiki versions, or bugs may arise that disrupt essential features. Regular testing and updates are needed.
User Experience Issues: Slow loading times, broken links, and outdated content can negatively impact user engagement. Proactive maintenance improves usability.
Compliance Issues: Depending on the content of your wiki, you may have legal or regulatory requirements for data retention and security.

Maintenance checklists address these issues by ensuring that essential tasks are performed consistently and reliably.

Categorizing Maintenance Tasks

To make maintenance more manageable, it’s helpful to categorize tasks based on their frequency and complexity. Here’s a suggested categorization:

Daily Checks: These are quick tasks that should be performed every day to identify and address immediate issues.
Weekly Maintenance: These tasks require a bit more time and effort but are essential for maintaining overall health.
Monthly Maintenance: These are more comprehensive tasks that focus on performance optimization and security.
Quarterly/Semi-Annual Maintenance: These tasks involve deeper analysis and potential upgrades.
Annual Maintenance: These are the most extensive tasks, often involving major upgrades and security audits.

Daily Checks (5-15 minutes)

Check Recent Changes: Review the Special:Recentchanges page to identify any vandalism, spam, or potentially problematic edits. Implement rollback procedures for quick correction. Look for unusual patterns or edits from anonymous users.
Monitor Watchlist: If you have a watchlist, review it for changes to pages you're interested in.
Check Error Logs: Examine the MediaWiki error logs for any new errors that need investigation. These logs can provide clues about potential problems.
Review Special Pages: Quickly scan Special:Brokenlinks, Special:Deadlinklist, and Special:Lonelypages for immediate issues.
Verify Basic Functionality: Test key features like search, editing, and page rendering to ensure they're working as expected.

Weekly Maintenance (30-60 minutes)

Run Maintenance Scripts: Utilize the maintenance scripts provided with MediaWiki. Specifically, run `update.php` to update internal search indexes. This improves search performance. See Maintenance scripts for details.
Review User Rights: Ensure that user permissions are appropriate and that no unauthorized users have administrative access. Implement the principle of least privilege.
Check Extension Updates: Verify if there are updates available for any installed extensions. Outdated extensions are a common security risk.
Monitor Server Health: Check server resource usage (CPU, memory, disk space) to identify potential bottlenecks. You can use tools like `top` or `htop` on Linux servers.
Review Category Structure: Ensure categories are well-organized and that pages are properly categorized. This improves navigation and discoverability. Consider using semantic wiki principles for enhanced categorization.
Spam Prevention: Review blocked users and spam filters. Adjust settings as needed to improve spam detection. Consider using extensions like SpamBlacklist.

Monthly Maintenance (1-3 hours)

Database Optimization: Optimize the MediaWiki database tables to improve performance. Use `mysqlcheck` or similar tools to check and repair tables. Regular optimization prevents database bloat. This relates to Database replication.
Database Backup: Perform a full database backup. Store backups in a secure, off-site location. Test your backup restoration process regularly.
File Uploads Review: Review recent file uploads for inappropriate content or potential security risks.
Check for Broken Images/Files: Identify and fix any broken images or files.
Analyze Page Traffic: Use web analytics tools (e.g., Google Analytics) to analyze page traffic and identify popular content. This information can inform content strategy.
Security Scan: Perform a basic security scan of the wiki using tools like OWASP ZAP or Nikto. This can identify potential vulnerabilities.
Review and Update Documentation: Ensure that wiki documentation is up-to-date and accurate. This is crucial for user support.

Quarterly/Semi-Annual Maintenance (4-8 hours)

MediaWiki Upgrade: Upgrade to the latest stable version of MediaWiki. This provides bug fixes, security improvements, and new features. *Always* back up your wiki before upgrading. Test the upgrade on a staging environment first. Consider using Continuous integration for automated testing.
Extension Updates (Comprehensive): Update all installed extensions to their latest versions. Test each extension after updating to ensure compatibility.
Review Configuration Settings: Review the `LocalSettings.php` file and other configuration settings to ensure they are optimal for your environment.
Performance Testing: Conduct performance testing to identify bottlenecks and optimize performance. Use tools like Apache JMeter or LoadView.
Security Audit (Intermediate): Perform a more thorough security audit, focusing on potential vulnerabilities and configuration weaknesses. Consider hiring a security professional.
Review and Update Policies: Review and update wiki policies (e.g., editing guidelines, privacy policy) to ensure they are current and compliant.

Annual Maintenance (8+ hours)

Full System Backup: Perform a full system backup, including the database, files, and configuration settings.
Security Audit (Comprehensive): Conduct a comprehensive security audit by a qualified security professional. This should include penetration testing and vulnerability assessments.
Review and Revise Disaster Recovery Plan: Update your disaster recovery plan to ensure it's effective and up-to-date.
Content Audit: Perform a content audit to identify outdated, inaccurate, or irrelevant content. Archive or delete as appropriate.
Accessibility Audit: Ensure that the wiki is accessible to users with disabilities. Follow accessibility guidelines (e.g., WCAG).
Review and Update Server Infrastructure: Evaluate your server infrastructure and make any necessary upgrades or changes. Consider using a Content Delivery Network (CDN) for improved performance.

Creating a Checklist Document

To ensure consistency, create a checklist document (e.g., a spreadsheet, a wiki page, or a task management tool) that outlines all the maintenance tasks, their frequency, and the person responsible for performing them. The checklist should include:

Task Name: A clear description of the task.
Frequency: How often the task should be performed (daily, weekly, monthly, etc.).
Responsible Party: The person or team responsible for completing the task.
Instructions: Detailed instructions on how to perform the task.
Status: A field to track the status of the task (e.g., To Do, In Progress, Completed).
Last Performed Date: The date the task was last completed.

Automation

Where possible, automate maintenance tasks using cron jobs or other scheduling tools. For example, you can automate database backups, index updates, and security scans. Automation reduces the risk of human error and ensures that tasks are performed consistently. Consider utilizing API access for automated tasks.

Monitoring and Alerting

Implement monitoring and alerting systems to proactively identify potential problems. For example, you can set up alerts to notify you if server resource usage exceeds a certain threshold or if the database is running slow.

Adapting the Checklist

This is a general guideline. Adapt the checklist to your specific wiki’s needs and resources. A small, personal wiki will require less maintenance than a large, heavily-used wiki. Regularly review and update the checklist to ensure it remains relevant and effective. Remember to consider the specific extensions you are using and their maintenance requirements. Understanding semantic web technologies can help streamline content management.
