Vigilant Healthchecks

Vigilant Healthchecks provides a REST healthcheck endpoint at /wp-json/vigilant/v1/health with an admin interface to conrol which checks are executed. This plugin is designed to integrate with Vigilant, an all-in-one web monitoring tool which can be self-hosted. Key Features

• Protected REST endpoint with configurable token.
• Built-in checks for database connectivity, core versions, plugin updates, cron freshness, Redis, and WordPress Site Health issues.
• Metrics catalogue for memory, disk, CPU load, and database size with sensible caching defaults.
• Extensible registry and hooks (vigilant_healthchecks_prepare, vigilant_healthchecks_cron_threshold, vigilant_healthchecks_database_size_cache_ttl) so you can add custom checks and metrics.
• Scheduler heartbeat (vigilant_healthchecks_cron_monitor) that validates WP-Cron is actually running and reports stale schedules.

How It Works

1. Configure the bearer token under Settings → Vigilant Healthchecks; every REST request must include Authorization: Bearer <token>.
2. Toggle the checks and metrics you want to expose; disabled items are never instantiated so they have zero runtime impact.
3. Call the endpoint yourself or configure your website in Vigilant.
