Distributed Tracing Support in N|Solid [10/10] The best APM for Node, layer by layer.

Complex modern systems are the new reality for infrastructure teams, and this is due to the evolution of Cloud Computing and working with Distributed systems, containerization, and microservices by default. The teams now have different infrastructures and virtual services with which they must take care of scalable, reliable, and performative applications.

Global Alerts & Integrations in N|Solid [9/10] The best APM for Node, layer by layer.

N|Solid provides unparalleled performance and security monitoring for various deployments and team sizes. You can configure the N|Solid Console to notify you when new vulnerabilities are found in your applications. DevOps professionals looking after applications running in production can be notified of performance and security issues earlier and then collaborate wherever they want (Slack, Microsoft Teams, email, etc.) to resolve them.

9 Best WebSocket Libraries for Node.js in 2022

The ability to establish communication between your browser and the servers is now possible due to WebSocket libraries. It enables you to send messages to that server and receive event-driven responses in return. Even without checking with the server for updates. Additionally, some developers choose to use the WebSocket libraries' APIs. This is done to provide asynchronous communication between the server and your browsers.

Vulnerability Scanning & 3rd-Party Modules Certification in N|Solid [8/10] The best APM for Node, layer by layer.

NCM —NodeSource Certified Modules— is the secure, reliable way to take advantage of the massive ecosystem of Node.js packages. Certified modules are compatible with Node LTS and monitored continuously to identify risk over time. Certification guarantees no security vulnerabilities or unverified code in modules or dependencies and is easy to set up and manage. No workflow changes are required.

Capture Heap Snapshots in N|Solid [7/10] The best APM for Node, layer by layer.

One of the first needs of developers is debugging memory-based issues in Node.js applications quickly and effectively. Still, before we jump right into the Heap Snapshot concept, it's essential to understand what a memory leak is. A basic definition that I would apply in this context is: Memory leaks are quite common in production applications. Fortunately, they usually aren't difficult to find.

Worker Threads Monitoring in N|Solid [6/10] The best APM for Node, layer by layer.

One of the more popular ways for developers to use Node.js is to leverage Worker Threads. Workers (threads) are useful for performing CPU-intensive JavaScript operations, according to the official documentation. They have proven to be the best solution for CPU performance due to the following features.

Memory Anomaly Detection in N|Solid [5/10] The best APM for Node, layer by layer

Anomaly detection refers to the problem of finding patterns in data that do not conform to expected behavior. Understanding memory management reduces the possibility of wasting your application's resources and the unexpected effects on performance. According to Sergey Kibish, Anomalies can be illustrated in a simple two-dimensional space.

Fetch API in Node.js

Fetch() support is now available in Node.js as an experimental core feature. Fetch() is a well-liked cross-platform HTTP client API that functions in browsers and Web/Service Workers. Many people who want to build cross-platform HTTP request code and are familiar with the fetch() API structure and call patterns have long demanded the addition of fetch() support. The node-fetch module was created specifically to backfill this feature in Node.js, which is why it exists.

HTTP Tracing in N|Solid [4/10] The best APM for Node, layer by layer

In Node.js, you can centralize tracing information generated by V8, Js code, and userspace code. Directly in the APMs, tracing means that you will have a detail of each flow in your application's process; this means that you will have records available of each time a function is called or a database or external information is called. With tracing, you will have a way to capture, visualize and analyze traces across complex architectures, including architectures that use monoliths and microservices.

CPU Profiling in N|Solid [3/10] The best APM for Node, layer by layer

Review your applications in detail with CPU Profiles in N|Solid and find opportunities for Improve code. You can use the CPU Profiler tool in N|Solid to see which processes consume the most percentage of CPU time. This functionality can give you an accurate view of how your application is running and where it is taking up the most resources.
