usage

node-usage

linux process usage lookup with nodejs

• With node-usage we can lookup cpu and memory usage of any accessible process on the system.
• This is 98% JavaScript and logic is based on procps

Example

Code

var usage = require('usage');

var pid = process.pid // you can use any valid PID instead
usage.lookup(pid, function(err, result) {
	
});

Result Object

{ 
	cpu: 10.6, //in percentage
	memory: 100065280 //in no of bytes
}

Motivation

• Some NodeJS PAAS providers do not expose us an interface to monitor CPU and Memory usage of our apps.
• They asks us to go for somewhere else for that which I don't want to go (or simply I cannot go)
• So node-usage was born to tackle on this.
