Top 5 Node.js Monitoring Tips for App Performance Improvement


The framework of Node.js has gained immense popularity in the past few years. It has now turned out to gain the tag of being a global development framework for different business organizations that are seeking to inculcate efficient, data-intensive yet lightweight “Real Time Applications which are implemented across various distributed devices. Certain prominent cool products which can be devised through Node.js encompass:

  • TOOLS.

Considering the significance of organizational reliability on Node js application developments in regards to the delivery of successful apps, it is very important that business organizations should give priority to the monitoring aspect of Node.js. The technology team requires to be completely aware of the reason why the customer happens to abandon the application within complete transactions and note down key factors that lead to the app’s poor performance.

This is more prominently relevant when there is a decrease in the app performance. Most of the software companies rely on the node js application development for gaining assistance with the setting up and monitoring of the automatic alerts. Node.js offers the functionality of both application server and web server. It is considered to be the main tool for all sorts of delivery and development that are based on microservices.

It can augment or replace .NET or Java for BACKEND APPLICATION DEVELOPMENT. Node.js uses “Non-blocking I/O” and is single threaded. This feature allows it to support and scale hundreds of operations. It also shares such architectural features with NGINX and resolves the C10K issues. This feature has been a support to around 10,000 connections. Node.js is reputed for its productivity and performance of the developer.

When can Node.js go wrong?

Node js application development has some vulnerabilities and weak points too which can make the all the systems based on the program to have highly prone to crash or underperform. Issues mostly arise when any web application that is based on node.js experiences fats growth in the traffic.


Node.js is also a powerful tool for running and creating application logic which generates variable web content for your page. However, it is not that great for the static content such as JavaScript and images files. It can also be considered not so great for balancing of load across different servers.

To get the most out of the node js application development program, you require caching of static content, to load and proxy balance among different application servers and managing the contention of port between different clients, helpers and Node.js like Socket.IO server. There are many ways through which app performance of Node.js can be monitored in a better way. These are:


Node.js is mostly used structured for gaining scalability. The web server part of it can also deal with more number of traffic on the internet. However, it was not the key objective for which Node.js was built.

If you happen to have a website that has some traffic on it, the basic step that needs to be incorporated for increasing the performance of the application is by putting a “Reverse Proxy Server” in the Node.js server. This secures the server from being exposed to the traffic directly and facilitates a huge amount of flexibility regarding usage of many application servers. It also assists in balancing the load across different servers along with cashing the web content.

2) Tracking response time of the application

Considering the lack of attention from many numbers of customers, keeping track of the response time for mobile/web app has gained a great amount of significance. Response times are equal to the application performance in real time. It can be measured against the parameters for evaluating the decrease in the performance.

When node js application development is considered, the HTTP requests are considered as the basic interaction points which are to be tracked. Response and transaction times reflect the performance in the business and can assist you in making the important decisions in the business like requirements for measuring the resources.

3) Regulating API configurations and dependencies

Any application like node js cannot be implemented in isolation. A conventional Node.js can integrate with a database, caching layer, queue server, a legacy system or any online service. It is crucial for companies to begin regulating the external dependencies and the node applications, their availability and quality for removing the barriers in the app performance.

4) Target lags in the event loops

Node.js ‘asynchronous functionality makes the products of Node very nimble and swift. There are many times when the event loops can perform as an application performance bottleneck. Hence, it is very important for organizations dealing with node js application development to gain comprehension regarding when and why slowing done of an event occurs.

5) Evaluate the CPU usage

The application of Node.js does not conduct the CPU intensive performance. In the scenarios where the high activity of CPU is identified, it denotes to the large volume of Synchronous work. This can result in blocking of the event loop. Hence, organizations need to devise CPU profiles for tracking the CPU usage.
