This module provides a simple API for spawning child processes that can share the same server ports and communicate with each other. To enable cluster mode, you can use the built-in cluster module in Node.js. This can help improve CPU utilization by allowing your application to handle more requests in parallel. Node.js supports cluster mode, which allows you to spawn multiple instances of your application and distribute the load across them. Here are a few tips for optimizing CPU utilization of Node.js on Amazon EC2: Use Cluster Mode Once you’ve identified performance bottlenecks and monitored CPU utilization, you may want to optimize your Node.js application to improve its performance. You can then use the pm2 monit command to view real-time metrics on CPU utilization and other performance metrics. To use PM2 to monitor CPU utilization, you can start your Node.js application with the pm2 start command, which will launch the application in a managed process. It also includes a built-in monitoring tool that displays real-time metrics on CPU utilization, memory usage, and more. PM2 is a process manager for Node.js applications that provides features like automatic restarts, log management, and load balancing. You can then use the -inspect flag to connect to the running process and analyze the profiling data using a tool like Chrome DevTools. To use Node.js Profiler, you can start your Node.js application with the -prof flag, which will generate a profiling file. It provides detailed information on the CPU utilization of your application, including the percentage of CPU time spent executing each function.

Node.js Profiler is a built-in tool that helps you identify performance bottlenecks in your Node.js application. You can then set up alarms to notify you when CPU utilization exceeds a certain threshold. To monitor CPU utilization using CloudWatch, you can create a custom metric that tracks the CPU usage of your Node.js process. You can use CloudWatch to monitor CPU utilization of your EC2 instances, including those running Node.js applications. To monitor CPU utilization of Node.js on Amazon EC2, there are a few tools you can use: Amazon CloudWatchĪmazon CloudWatch is a monitoring service that provides metrics on resource utilization, application performance, and operational health. This may mean that you could be paying for more resources than you actually need, or that you could optimize your application to make better use of the available resources.

Low CPU utilization can indicate that your application is not fully utilizing the available resources of the EC2 instance. High CPU utilization can indicate that your application is under heavy load, and may need to be optimized or scaled horizontally to handle more requests. Monitoring CPU utilization is important because it can help you identify performance issues and optimize your application’s performance.

In this blog post, we’ll explore how to monitor and optimize CPU utilization of Node.js on Amazon EC2. High CPU utilization can lead to performance bottlenecks, slower response times, and even crashes. If you’re running Node.js applications on Amazon EC2 instances, you may want to keep an eye on the CPU utilization of your application.ĬPU utilization is a measure of how much of the CPU’s processing power is being used at any given time.
