![]() NGINX can report basic activity metrics exactly like open source NGINX, but it also provides a secondary module that reports metrics slightly differently. Whatever is your NGINX use case, you will no doubt want to monitor how many clients requests your servers receive and how those requests are being processed. We generally monitor these three key categories of metrics: Server error rateindicates how often your servers are failing to process requests that seem reasonable and Request processing time, which describes how long your servers are taking to process client requests. Monitoring will include requests per second for most NGINX users in some metrics, which provides a high-level view of combined end-user activity: You can catch two categories of issues by monitoring NGINX: (a) resource issues within NGINX itself and (b) problems that develop elsewhere in your web infrastructure. However, this article does not directly address NGINX monitoring for these use cases. NGINX can also be used as a mail proxy and a generic TCP proxy. In addition to its HTTP server capabilities, NGINX can also function as a proxy server for email (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers. It started out as a web server designed for maximum performance and stability. NGINX is open-source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. Telegraf: An Open-source project, plugin-driven agent to collect and send metrics. Grafana: An Open-source project for analytics software and visualization of the metrics from any database. Prometheus: An open-source, time-series database for event monitoring and alerting managed by the Cloud Native Computing Foundation (CNCF). The main goal is a quick deployment and configuration using well-known open-source projects like Grafana, Prometheus, and Telegraf. This article will guide you on how to get Nginx Web Server metrics and visualize them. It will also keep you updated about the current state and health of your application. Nevertheless, it is paramount to keep track of the performance and availability that would help you to proactively prepare yourself for the worst scenarios like sudden/unexpected hikes in traffic. Nginx is one of the most popular and widely used web servers mostly because of its speed and reliability.
