How to monitor NGINX

NGINX is a popular HTTP server and reverse proxy server that serves static content very efficiently and reliably using relatively little memory. It can also be used as a mail proxy and a generic TCP proxy. Monitoring NGINX allows users to catch resource issues within the server itself, as well as problems developing elsewhere in their web infrastructure. Key NGINX metrics include requests per second, server error rate, and request processing time. By monitoring these metrics, users can gain valuable insights into the health and activity levels of their web infrastructure.
