Canary Site Monitor

Canary Site Monitor checks a WordPress site for common failure conditions and reports what it finds in plain language, so problems are noticed before they affect visitors. Most things that go wrong on a WordPress site go wrong quietly. A plugin deactivates after an update. Bots generate hundreds of 404 responses a day. Database tables drift out of sync with the plugins that own them. None of it announces itself, and by the time it becomes visible it has usually been happening for a while. Checks run on WP-Cron schedules, not on front-end page loads, and the results appear on a dashboard in the WordPress admin. Features

• Database scanner - compares your live table structure against the expected schema for WooCommerce, Yoast SEO, Rank Math SEO, Redirection and Flamingo. Detects missing tables, missing columns, column type mismatches, collation mismatches, and orphaned or MyISAM tables.
• Plugin watchdog - records plugin activations and deactivations with timestamp, user and IP address, and raises an alert when three or more plugins are deactivated at once.
• 404 flood monitor - logs 404 requests, identifies known bots and crawlers, and raises an alert when a single IP address exceeds a threshold you configure.
• Site-wide table audit - lists every database table with its row count, storage engine, size and status.
• Admin dashboard - a health score, metric cards and a list of recent alerts.
• CSV export - download the 404 log, plugin change history or database issue log.

Every feature listed above is fully functional. Nothing in this plugin is locked, time-limited or gated behind a licence key. Canary Site Monitor reads and reports. It does not modify your database, your plugins or your site configuration. This is not a security plugin. It does not scan for malware and does not provide a firewall. A separate paid plugin is available A separate commercial plugin, distributed from getwpcanary.com, adds database repair, a daily email digest, debug log analysis, cron health checks, and PHP resource monitoring. That code is not included in this plugin and is not required for anything described above.
