Node.js developers can find it under the Apache 2 License on Github. Prometheus is a prominent open-source, community-powered APM developed at SoundCloud in 2012. Keep in mind, to use Appmetrics, you will need to get node app metrics from, Github, and IBM SDK for Node.js. Notable features of Express Status Monitor include:Īppmetrics is a top-notch performance monitoring, open-source tool managed by IBM. Express Status MonitorĮxpress Status Monitor is an open-tool that offers real time monitoring of Express-based node servers.įor those who don’t know, Express.js–or simply Express–is the “ de facto standard server framework for Node.js”.
Keep in mind, to utilize this tool, you will need to install NPM.
It is a straightforward tool for those who run and monitor live production workloads from a CLI or web interface. PM2 is another popular Node.js monitoring tool.
Detailed performance data helps you understand how your code is performing and how to improve it. Retrace uses lightweight profiling to automatically track key methods in your code. Retrace users proactively identify more issues in QA and continuously improve and observe applications in production environments. It can be used to improve the performance of your applications. Retrace is a popular cloud-based tool for APM used by organizations of all sizes. Node js has a wide scope of functionality and so as you might have expected, there are quite a few Node.js monitoring tools on the market, all in different shapes and sizes. Event loop – allows Node.js to perform non-blocking I/O operations.Memory usage and leaks – a useless block of memory that results in crashes and slowdowns.Garbage collection – automatic memory management.Bandwidth – the maximum rate of data transfer.Average response time – the amount of time the server takes to return the results of a request.CPU usage – how much the processor is working.Specific things you should evaluate include: Let’s get into the nitty- gritty, shall we?
So we’ve established why you need to invest in an APM system, but what are you monitoring with it? Essentially, you are monitoring server health and resource utilization (poorly-optimized applications use more resources, cost you more money, and are slow). If you catch small problems early, they won’t turn into big problems later. You will want to install an APM tool to mitigate any disaster–even the disasters you cannot see (bad code can go unnoticed for an extended period of time).ĪPM systems are extremely helpful because they pinpoint the problem in the code so you can fix it quickly. That’s more than half a million dollars lost for every hour that your server is offline! The cost of unplanned server downtime is between $5,600-$9,000 per minute. Unfortunately–once customers lose trust in you–it’s hard to get them back. If it’s not running correctly, customers will get a loading screen, and they will undoubtedly be turned off by an error message. Monitoring your Node.js server means you are making sure it’s performing optimally and nothing is blocking the thread or event queue. What is Node.js Server Monitoring, and Why Is It Important To Use an APM?įirst, let’s quickly review what exactly Node.js monitoring is.
