Quick Summary
Drupal powers 1.3M+ sites and is a high-value target for attackers — Drupalgeddon-class vulnerabilities can be exploited within 48 hours of disclosure. Lemwatch fingerprints your Drupal version and modules from the outside (no module install), cross-references SA-CORE and SA-CONTRIB security advisories, and monitors uptime, response time, and Core Web Vitals — all in one place.
- Detects Drupal 7, 8, 9, 10, and 11 — flags end-of-life versions
- Alerts within minutes of a matching SA-CORE / SA-CONTRIB advisory
- Tracks Acquia, Pantheon, Platform.sh, and self-hosted environments
- No module install, no admin access — runs entirely from outside
Why Drupal Sites Need Dedicated Monitoring
The Drupal Reality
- Critical security vulnerabilities require rapid patching
- Complex module dependencies create update risks
- Self-hosted infrastructure needs constant monitoring
- Cache misconfiguration silently kills performance
The Lemwatch Solution
- Version tracking with security advisory alerts
- Module detection and health monitoring
- Performance and uptime monitoring 24/7
- Cache validation and CDN integration checks
How Drupal Monitoring Works
Auto-Detect Drupal
Lemwatch identifies Drupal sites via generator meta tags, Drupal.settings JS objects, and known file paths.
Security-First Checks
We prioritize security — version detection, header analysis, and known vulnerability cross-referencing for Drupal core and modules.
Proactive Alerts
Get notified about security advisories, performance degradation, and downtime before they become incidents.
Complete Drupal Monitoring
Security, performance, and uptime monitoring purpose-built for Drupal.
Security Update Tracking
Drupal has a history of critical security vulnerabilities. We monitor your version and alert you when security patches are released.
Module Audit
Detect installed Drupal modules and track which ones may have known vulnerabilities or need updates.
Performance Monitoring
Track page load times, Core Web Vitals, and server response times for your Drupal site.
Cache Health
Verify Drupal caching layers are working properly — page cache, dynamic page cache, and CDN integration.
SEO & Indexation
Monitor meta tags, structured data, and search engine indexation across your Drupal pages.
Enterprise Alerting
Multi-channel alerts via email, Slack, and webhooks — designed for enterprise teams managing Drupal infrastructure.

Why Drupal performance monitoring is different
Drupal is unusual in the CMS world: it powers enterprise government, healthcare, and higher-education sites that cannot tolerate downtime, but its module ecosystem moves fast and its security release cycle is unforgiving. A single unpatched contributed module can compromise the entire site, and exploitation kits for known CVEs tend to circulate within 24–72 hours of a Drupal Security Team advisory.
Most general-purpose uptime tools treat Drupal like any other web app — they ping the homepage and report a 200. That misses the things that actually break Drupal in production: a stale page cache serving logged-out HTML to logged-in users, a Views block timing out under load, a cron run that silently stops firing, or a module update that introduces a fatal in a rarely-visited admin path. Lemwatch is purpose-built to surface all of those signals.
On top of the standard HTTP uptime check, Lemwatch parses Drupal fingerprint markers (the X-Generator header, Drupal.settings JSON, /core/misc/ asset paths) on every cycle. When your installed version no longer matches the latest secure release published on drupal.org, the platform raises an advisory-tagged alert with a direct link to the patch — usually within minutes of the security team's announcement.
Performance gets the same treatment. Lemwatch tracks Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint against Google's Core Web Vitals thresholds, with separate mobile and desktop scoring. Cache layers — internal page cache, dynamic page cache, BigPipe, Varnish, CDN — are validated on every run by inspecting Cache-Control and X-Cache headers, so you'll know the moment a deploy accidentally disables caching and tanks your TTFB.
Built for Acquia, Pantheon, and Platform.sh
Managed Drupal hosts hide a lot of infrastructure behind their dashboards, but they don't tell you when your version drifts behind the official secure release, when your modules need updating, or when an edge cache is misconfigured. Lemwatch sits outside your hosting provider and verifies the user-facing reality — exactly what Google and your customers see.
Headless and decoupled Drupal
If you've moved to a headless architecture (Drupal as a JSON:API backend behind a React or Next.js frontend), Lemwatch monitors both halves: the consumer-facing app for Core Web Vitals and uptime, plus your /jsonapi and /graphql endpoints for response time, schema drift, and authentication failures.
