This article is aimed at providing a basic understanding of application performance monitoring (APM) tools and how they can be used to improve the performance of web applications. It is by no means an exhaustive guide, but it should provide enough information for beginners to get started. To know more about application performance monitoring services, you can also check out this site .
There are a number of different APM tools available, and each has its own strengths and weaknesses. Some of the more popular tools include New Relic, Appcelerator Titanium, and Dynatrace. There are also a number of DIY options available, such as Apache JMeter or Nginx Bench.
The first step in using APM tools is understanding what you're looking for. You need to know what constitutes an acceptable response time for your application, and how to measure that. You should also be aware of common performance issues and how to identify them.
Once you have a good understanding of what's going on behind the scenes, you can start to take steps to improve the performance of your application. One important step is identifying where the bottlenecks are — these are the areas where your application is performing poorly relative to other parts of the system. Once you've identified the bottlenecks, you can start to work on addressing them , perhaps by testing to see if your new solution addresses them and whether you will actually break anything else.
If your application is actually working correctly, with the exception of the performance issues, there's really not much more you can do to improve its performance. But if it's showing other symptoms — like a high error rate or slow response time — then there are things you can do to help your application respond well.
