Difficulties being solved using Java in the real world
We interviewed 11 business professionals, most of whom engaged in jobs related to the Java ecosystem. I asked them some questions about the actual problems they solved with Java in their career.
We interviewed these people:
Anthony Kilman, Tech Lead, AppDynamics | Gil Tene, CTO, Azul Systems | Bhartendu Sharma, Vice President of Operations, Chetu | Charles Kendrick, CTO and Chief effecect, Isomo

The overall visualization of Web application performance;
Visualize the performance of specific Web requests;
Automatically send alarms when Web application performance becomes worse or multiple errors occur;
When the volume of business is large, the response of the application is validated.

While performance is a very important part of many large software systems, it is also part of the automated test suite in the product delivery pipeline, but it cannot be optimized blindly and without purpose. Instead, specific optimizations should be made to the performance bottlenecks already mastered. Not
If you've read the previous how to monitor NGINX, you should know how much information you can get from several metrics in your network environment. And you see how easy it is to collect metrics from NGINX-specific foundations. But to achieve a comprehensive, continuous monitoring NGINX, you need a powerful monitoring system to store and visualize metrics that will alert you when an exception occurs. In this article, we will show you how to install NGINX monitoring using Datadog so that you can
