Whenever there is a bad story about the Node.JS covered, it is usually connected with its performance. This does not imply that the application has many problems compared to other technologies. For you to avoid performance issues with the application, it is important for you to understand it comprehensively.
In this article, we are going to deal with how the application keeps the memory and how we can trace memory related issues. Unlike the other platforms, the Node.jS application runs for a long time. Though this may have positive impacts like allowing connections to the database be made once, it may also bring some problems in the long run.
Definition of Tracing as applied in Node.JS applications
Node.JS tracing is a module that assists in identifying and execution of the node application pattern. This helps you to monitor the application and location of data both on the function and system level. Tracing offers a mechanism where information generated by V8, Userspace code and Node core can be traced at a central point.
Tracing is able to monitor your node applications by closely following JavaScript entry and exit points thereby, recording time that has passed to each function. You may not notice the effect of tracing during the first time but, afterward one can clearly tell its effects. It is possible to activate trace on a running Node.JS application or before the application has been started.
Advantages of Tracing in Node.JS application
- -It helps to fix memory problems
- -Tracing helps you to understand better what might be slowing you down. It is able to achieve this by requesting the profiles of the CPU and memory screenshots in production.
- -It helps Node.JS teams to have an insight on performance and this helps them to offer the best service to their clients.
- -It helps to show how your site is available to your clients in different regions- this is aimed at enhancing user experience from your customers from different regions
