1. Monitor Key Metrics

Monitoring key metrics such as CPU usage, memory usage, network traffic, and disk I/O can give you an overview of how your server is performing. It’s crucial to have a baseline of your server’s performance to identify issues and potential bottlenecks.

2. Set Up Alerts

Setting up alerts for critical events, such as downtime or high CPU usage, is essential to ensure timely remediation. It’s best to set up alerts via multiple channels, such as email, SMS, and push notifications, so that you can quickly respond to any issues.

3. Use the Right Tools

Several monitoring tools, both open-source and commercial, are available for monitoring Nginx. Some popular options include Zabbix, Nagios, and Datadog. Choose a tool that fits your needs and budget.
