![]() Prometheus is 100 open source and community-driven. 2 If you want to go with native nodejs solution you can use moryUsage () function. ![]() ![]() It’s the most notable and famous open-source monitoring tool you can use today. Unless you’re living under a rock, you must have heard of Prometheus. Let timesAfter = os.cpus().map(c => c. By monitoring heap memory and suspension metrics for V8 JavaScript engines, Dynatrace enables you to track heap memory usage and growth in your production. Once you run your server go to the /status route to monitor your Node.js metrics. Let timesBefore = os.cpus().map(c => c.times) Initial value wait at little amount of time before making a measurement. However, for non-default heap settings maxoldspacesize, the above illustration and behavior still holds true, and you should take care when deciding your memory tuneable. Please corret me if my assumptions are wrong. Node.js 12.x addresses some of these inconsistencies by limiting the default heap size of Node.js well within the available limit, if running under container environments. music playback increases the cpu load more than in the Windows task manager). I am assuming t_idle + t_user + t_sys = total cpu time and results are kind of similar to the ones of my Windows task manager, however, the usage seems little more sensitive to me (e.g. Most of the memory allocation is from dependencies and Node.js internal You can also use Clinic Doctor to monitor the memory consumption during the process execution. RisingStack Engineering This article helps you to understand what to monitor if you have a Node.js application in production, and how to use Prometheus an open-source solution, which provides powerful data compressions and fast data querying for time series data for Node.js monitoring. As I found no code to solve this problem and don't want to rely on other packages just for some lines of code, I wrote a function that calculates the average CPU load between two successive function calls.
