Sharing is caring!

Node.js is an open-source and very lightweight framework with few modules built on Chrome’s V8 JavaScript engine. It is also faster than most other frameworks because it is an asynchronous system by default. However, DevOps still require Node.js monitoring tricks to ensure superior performance to other frameworks. 

To understand how relevant Node.js remains, consider that the framework is used by Amazon, PayPal, Netflix, LinkedIn, and other high-use, high-visibility service providers. The Node.js framework powers approximately 20 million websites worldwide and assists a variety of businesses in reducing development costs by up to 58 percent.

Despite the hype surrounding the Node.js framework, developers, like any other website framework, must track the overall performance of the apps that run on it. Keeping this in mind, let’s look at some of the key performance metrics you should be tracking for Node.js-powered applications.

1. System Health And Downtime

System downtime is the last thing you want to happen with your application. Downtime not only reduces potential earnings but also causes customers to lose trust in your firm. Keeping an eye on the health and downtime of Node.js applications is critical to ensuring that users are not inconvenienced by the service you provide.

2. Resource Utilization

If your application’s services aren’t optimized, you could be in trouble. These applications have high latency and even cost more to run and maintain. Using Node.js monitoring to identify and resolve bottlenecks ensures optimal performance in the infrastructure and application.

3. API Latency

Application latency has a significant impact on a company’s success or failure. The average wait time for loading speed is around two seconds, and anything longer may lose customer interest. This is no secret, so keeping an eye on your API latency for speed and wait-time is critical.

4. Error Rates And Handlings

If a failing code goes unnoticed for an extended time, it can become a fatal bug. Furthermore, even for large, established companies, the traditional method of users reporting bugs no longer works. Users today leave an application or website when they encounter a bug, so it’s best to have an automated way to monitor error rates – a critical metric for monitoring Node.js applications. 

Node.js Application Monitoring Tools

Aside from simply creating metrics for Node.js applications, a variety of monitoring tools can be used to ensure that all of your Node.js applications are performing optimally.

1. Retrace

Retrace is a cloud-based application performance management tool that is ideal for proactive businesses in detecting problems during production. However, the tool can also come in handy when troubleshooting errors during the production phase.

2. PM2

PM2 is a simple monitoring tool for Node.js. PM2, as a daemon process manager, enables developers to prevent their applications from failing or having bugs. In addition, the PM2 Node.js application monitoring tool includes an integrated log management feature and app auto-clustering. Developers must use the npm -version command to install the NPM.

3. App Metrics

App Metrics is an open-source performance monitoring tool managed by IBM that collects data from various aspects of the app, such as garbage collection and database performance. The tool provides comprehensive monitoring of various aspects of application performance, ranging from the complexities of data transactions to basic metrics such as network speed.

Last Words

The Node.js framework is a well-known and beneficial framework for major corporations worldwide. Continuous monitoring of Node.js applications, on the other hand, can lead to more profitable campaigns and higher customer satisfaction.

Application monitoring should be done both during development and after deployment. Monitoring can help in denoting patterns of application performance as influenced by end-user usage, in addition to simply pointing out errors and bugs.
