Web Server Load Balancing with NGINX Plus

The bigger and busier your site, the more important it is to monitor it. A good monitoring solution gives you visibility into your site helping you maintain uptime, performance, and security. Monitoring is one of the most popular topics on the NGINX blog, with a completely new, NGINX‑focused monitoring tool – NGINX Amplify – added in the last year.

There are three types of monitoring solutions we’ve highlighted on the NGINX website:

  1. Active health checks and monitoring in NGINX Plus.
  2. Third party solutions from NGINX partners such as AppDynamics, Datadog, Dynatrace, and New Relic.
  3. NGINX Amplify, our new tool for monitoring application delivery with NGINX and NGINX Plus – introduced in 2016, and now in a very popular public beta.

Active Health Checks and Monitoring in NGINX Plus

Active health checks are one of the most useful features in NGINX Plus. A server that goes down can’t, by definition, tell you so. A server that works incorrectly (sends incorrect responses) is even harder to pinpoint. Active health checks continually test the health of your servers, enabling NGINX Plus to divert traffic away from servers that have failed or are malfunctioning.

Here are some resources to help you get the most out of active health checks and monitoring in NGINX Plus:

Third‑Party Solutions from NGINX Partners

Application performance management (APM) tools help you look closely at website problems that originate in the app itself, right down to helping you identify the specific lines of code that are causing a problem.

In addition to that, the app delivery infrastructure must be properly monitored. Since NGINX runs on more than half of the world’s busiest websites, it’s no accident that leading APM software integrates with NGINX and NGINX Plus. In fact, about a quarter of NGINX partners – AppDynamics, Datadog, Dynatrace, Librato, and New Relic – are APM providers. You can display metrics collected from NGINX and NGINX Plus within your APM dashboard.

The NGINX website and YouTube channel feature many contributions on the topic of APM from NGINX and our monitoring partners:

The Launch of NGINX Amplify

NGINX Amplify is a software as a service (SaaS) solution designed specifically to monitor NGINX Open Source and NGINX Plus, with additional metrics for NGINX Plus. With NGINX Amplify you can monitor all of your NGINX servers under a single pane of glass.

Over the last year, we:

NGINX Amplify has received widespread interest, and the monitoring agents have been installed on thousands of servers. It’s the subject of some of our most popular recent blog posts, including:

The role of NGINX Amplify has also been the subject of a well‑attended webinar. NGINX Amplify has been cited in a blog post about preventing security breaches and has been implemented alongside NGINX Plus to improve application delivery at a healthcare benefits coordinator.


You can monitor application delivery more effectively using NGINX Plus, NGINX Amplify, and third‑party tools from our partners. Separately and – for the most power – together, these solutions make it easier to deliver your web apps with high performance, scalability, reliability, and security.

An ever‑increasing number of NGINX Open Source users and enterprise sites that have to scale reliably and securely are moving to NGINX Plus.
