Drupal Insight

Drupal Insight is the definitive diagnostics, monitoring, and performance optimization telemetry toolkit for Drupal websites. It provides developers, agency teams, and site builders with real-time auditing of caching states, SQL queries, controller performance, queue metrics, and server execution environments.

Designed for enterprise stability, the suite has built-in database capping and request sampling to run safely in production environments with minimal overhead.

Features

• Site Health Dashboard: Visual overview of cached rendering, database profiles, and system health status.
• Performance Analyzer: Tracks slow routing controllers, entity load footprints, memory warnings, and Twig configs.
• Database Profiler: Aggregates query execution logs to isolate slow SQL, join storms, and duplicate queries.
• Cache Inspector: Monitors cache bin database sizes, hit/miss ratios, and frequently invalidated cache tags.
• Views Auditor: Inspects all active Views to detect missing caching configurations, DISTINCT query queries, and complex join chain loads.
• Queue Monitor: Lists active database queues, stuck leases, backlogs, and allows resetting or purging.
• Config Audits: Checks database active state configs against exported sync directories to isolate drift or unexpected overrides.
• Environment Inspector: Scans OPcache parameters, PHP memory configurations, secure directories, trusted host settings, and cron execution intervals.

Post-Installation

Once enabled, access the diagnostics suite in your admin interface:

• Insights Hub: Go to /admin/insight (or click the custom Insights tab placed directly after Configuration in your top administrative toolbar) to see a directory of all tool routes.
• Telemetry Dashboard: Go to /admin/reports/insight (available as the first sub-link in the Insights toolbar dropdown) to view real-time diagnostics gauges.
• Diagnostic Settings: Go to /admin/config/development/insight (available in the Insights toolbar dropdown) to configure telemetry sampling, memory thresholds, and cron notification alerts.

Additional Requirements

Requires no external PHP libraries or contributed modules; works fully with core Drupal 8.9+, 9.x, 10.x, and 11.x databases.

Recommended modules/libraries

• Admin Toolbar: Enables full hover-dropdown lists inside the administrative top-bar, allowing quick access to settings and queue logs.

Similar projects

• Webprofiler / Devel: While Devel and Webprofiler are excellent for local code debugging, they are resource-heavy and unsafe to run in production. Drupal Insight is optimized for safe, high-performance telemetry audits in production environments with capped database tables.
