How to Get Memory & CPU usage of Tomcat local server via NodeJS

Question

I'm building a Nodejs App that will monitor the performance of a local tomcat server.The two server are running on the same machine. I want to know several info about my Java ee App and tomcat server like CPU & Memory usage(Generaly important resource) I have tried os-utils module but it return the ressource used by my node server.

const os = require('os-utils');   
os.cpuUsage(c => console.log( 'CPU Usage (%): ' + c ));

It is a method to use the os module for nodejs to return the resource of another server running on same machine ?

const os = require('os');
os.cpus()

Answer 1

There is no such functionality in Node.js, and os-utils refers to Node.js process itself.

There are third-party packages that can do that. pidusage is a wrapper around ps and wmic commands depending on the platform, it parses their output and is capable of providing stats on CPU and RAM process use based on its PID.
