NGINX Amplify is a SaaS‑based monitoring tool for the open source NGINX software and NGINX Plus. With NGINX Amplify you can monitor performance, keep track of infrastructure assets, and improve configuration with static analysis. NGINX Amplify also monitors the underlying OS, application servers (like PHP‑FPM), databases, and other components. NGINX Amplify is simple to set up, yet powerful enough to provide critical insight into NGINX and system performance.
