Server Errors
Monitor for server errors and failed requests that prevent visitors from reaching your pages.
Feature
Health Monitoring
NorthDuty monitors your website's infrastructure health by checking server errors, connection issues, domain problems, security certificates, page speed, blank pages, and pages that fail to load properly.
Detect technical failures before customers notice
Health monitoring is the foundation of website reliability. It detects infrastructure-level problems that can make your site unreachable, slow, or broken for visitors.
NorthDuty goes beyond simple uptime checks. It monitors the full stack of technical signals that affect whether your website actually works for customers.
What health monitoring checks
NorthDuty monitors all the technical layers that affect your website's availability and performance.
Connection Issues
Track backend connection times and errors. Catch failed connections that break website functionality.
Domain Problems
Detect domain routing issues that can make your website unreachable even when servers are running fine.
Security Certificate
Monitor security certificate (the padlock) validity and expiration to prevent browser warnings.
Domain Expiration
Get alerts before your domain expires and your website becomes unreachable.
Page Speed
Track performance metrics that affect user experience and search rankings.
Blank Pages
Detect pages that load but show no content due to rendering failures or script errors.
Loading Failures
Catch pages that fail to load properly and break functionality without causing full outages.

- Network timing - measure connection and response times
- Third-party services - monitor external service dependencies
- Failed resources - detect broken images, scripts, and stylesheets
- Page availability - confirm pages are reachable during the latest check
- Response validation - verify pages return expected content

Common questions about health monitoring.
What is health monitoring?
Health monitoring checks the technical infrastructure of your website including server status, domain routing, security certificates, and page rendering to detect failures before customers are affected.
How often does NorthDuty check my site?
Current monitoring settings support health checks every 1, 5, or 15 minutes, depending on the schedule configured for the project.
What notifications are available?
NorthDuty projects can store email, Slack, and Telegram alert destinations, with alert rules for health score, response time, user-flow failures, visual differences, and SSL expiry.
Is health monitoring enough on its own?
Health monitoring catches infrastructure and rendering issues, but screenshots, visual diffs, and user-flow monitoring help catch visible regressions and broken customer journeys.
