NGINX (pronounced as "engine X") is an open-source web server that is commonly used for a wide-range ofcapabilities, serving as a reverse proxy, mail proxy, load balancing and HTTP cache. Applications Manager's NGINX monitoring tool offers complete visibility into performance, traffic behavior, and request processing. Its NGINX performance monitoring capabilities help DevOps teams monitor NGINX metrics such as active connections, upstream response time, and SSL health to ensure optimal server stability.
Why you need a complete NGINX monitoring solution
NGINX monitoring tools like Applications Manager enables you to track the performance of your NGINX web servers with the help of following capabilities:
Monitor key NGINX performance metrics in real time
Obtain a comprehensive overview on the performance of your NGINX servers in real time. Keep constant track of the availability and health of your NGINX web servers to ensure your web servers are up and running without any interruptions. Find out how long your NGINX web servers take to respond to requests to estimate the processing capacity of your web servers and to take corrective actions before end users are impacted.
Analyze NGINX requests and traffic patterns
- Obtain in-depth visibility into the request statistics of your NGINX servers to find out how much load your NGINX server is actually handling.
- Keep a close watch on the number of requests received per second by your NGINX servers.
- Gain detailed statistics on the number of requests received by your NGINX servers based on their states such as reading, writing, or waiting.
Monitor NGINX connections, active sessions, and client behavior
NGINX manages thousands of simultaneous client connections, so unusual spikes or slow-closing sessions can quickly affect performance. Monitoring active connections, reading/writing/waiting states, and keepalive usage helps identify traffic surges, slow clients, misconfigured timeouts, or bottlenecks in your backend services.
With Applications Manager, you can track the real-time connection count of each NGINX instance, monitor how clients are distributed across connection states, and get alerted when concurrency approaches critical thresholds. This visibility helps you detect connection buildup early, prevent resource saturation, and scale capacity proactively during high-traffic periods.
Monitor NGINX Plus performance metrics
If you use NGINX Plus, the commercial version of NGINX instead of the open source NGINX web server, you can make use of Applications Manager's NGINX Plus monitoring capabilities to obtain deep visibility into the health of your NGINX Plus servers. You can also get deep insights into additional enterprise-graded features, such as SSL, TCP connection statistics, server zones and their corresponding upstream servers, content caching, and more.
Using Prometheus? Integrate with Applications Manager for NGINX monitoring
If you already use Prometheus and scrape metrics from NGINX, you can simply integrate Applications Manager with Prometheus and visualize the NGINX metrics in Applications Manager.
