Keeping Nginx services running smoothly is critical for ensuring the availability of websites and applications. Manually monitoring and restarting services can lead to downtime and missed issues. This policy eliminates the guesswork, automatically restarting stopped services and providing instant alerts to your team.
Description
This monitoring policy tracks the Nginx service status on Linux devices tagged with “Nginx.” If the service stops or is not running, the monitor automatically attempts to restart it. At the same time, a real-time alert is generated, enabling IT Ops to take immediate action. This ensures that web services remain operational with minimal manual intervention.

Recommendations
Tagging: Ensure all relevant Linux devices are tagged with “Nginx” for targeted monitoring. We recommend automatically tagging to avoid missing key devices. See “Service Based Tagging” automation as an example.
Testing: Test the monitor in a controlled environment to confirm it correctly identifies and restarts the service.
Configuration: Review and optimize your Nginx configuration files to avoid restart loops due to misconfigurations.
Notification Settings: Configure alerting to reach the appropriate team members.
Documentation: Keep a record of your Nginx setup and dependencies for faster troubleshooting if issues arise.
FAQ
