0 Day Analytics

0 Day Analytics helps detect, inspect and respond to PHP and WordPress-level errors before they become production incidents. It is optimized for very large logs and common debugging/operational workflows. Core capabilities: – Efficiently reads very large (GB-sized) error logs without full-file reads. – Error Log Manager with search, filtering, and code-context viewing. – Cron Manager: list, edit, run, delete scheduled tasks; advanced filters. – Transients Manager: safely list, edit, delete DB transients. – Requests Viewer: inspect outgoing HTTP requests. – Mail Logger & Composer: record email history, view attachments, compose/send. – SMTP configuration and test email support. – DB Table Manager: inspect/delete records across tables. – Server Info: admin-bar badges and dashboard widget (CPU, memory, disk). – Plugin Version Switcher, Code Snippets module, code viewer, CSV export and dark mode. – Recovery Mode: one-time recovery links with Slack/Telegram/other channels. – Randomize error-log filename for security. – PHP Snippets: generate and execute your own snippets when you need them. Shortcodes are supported. – WP Hooks capturing / monitoring – very powerful tool to capture and monitor different (defined or custom) WP hooks (actions and filters). You can see selected or added hook output (result of triggering). Short Description Real-time error insight and recovery for WordPress — lightweight, fast troubleshooting toolkit with log management, cron/transient/request viewers, mail logging/composition, SMTP, and a recovery mode. Requirements & Compatibility WordPress 6.0+ (tested up to 6.9) PHP 7.4+ (compatible with PHP 8+) Not intended as a multisite recovery tool (see notes below) Best practices & Security Notes Keep log files outside the webroot when possible, or restrict access via server rules (.htaccess / nginx) to avoid public exposure. Use a randomized or non-obvious filename for error logs if stored in webroot. Limit plugin capabilities to trusted administrators (capability checks). Sanitize and escape all output; use nonces for state-changing actions. Secure SMTP credentials and prefer TLS/STARTTLS. Set file permissions tightly (e.g., 600/640) and restrict ownership to the web server user. Backup database/files before bulk delete or run operations. Disable or restrict high-frequency background polling in high-load sites. Usage notes & performance Default error history stores the last 999 errors (adjustable via Screen Options) to preserve performance on high-volume logs. No pagination on error logs by design to avoid repeated full-file reads. Optional DB-based PHP error logger exists for environments without disk logging; consider DB size and retention. Support & Notes Recommended: secure log paths and consider randomizing filenames. Disable unused modules to reduce footprint and attack surface. Recovery mode is limited on multisite installs due to WP core behavior. For bugs, feature requests or support, open an issue on the plugin page.
