Cron-job scheduler for VNstat

Purpose of this application

Dealing with bandwith limits from VPS hosts and wanting to avoid overages, this application runs in the background on my linux VPS and executes a cron job every day at 8AM, which is vnstat in a childprocess to pull the overall outbound bandwith amount.

Once the bandwith amount is half of the limit, an email is sent to inform of the amount.

This app uses node-cron for the scheduling and nodemailer for sending the emails

How to use

Require the module file, then instantiate an instance of the outboundtrafficmonitor object with the options as per the specification below.

const outboundTrafficMonitor = require('./src/outboundtrafficmonitor');

let monitor = new outboundTrafficMonitor(options);
monitor.initialize();

Options

Command	Description
schedule	Cron schedule expression (defaults to everyday 8am)
logfile	TRUE/FALSE creates logfile with each result in root dir
emailbody	FROM, TO, SUBJECT & TEXT subject & text default to message stating current mbs if empty
emailcredentials	EMAIL,PASSWORD,SERVER,HOSTNAME,PORT MUST either have server or hostname + port.

let options = {
	schedule: '0 * * * * *',
	logfile: true,
	emailbody: {
		from: 'dylansemailwarn@gmail.com',
		to: 'dylanelliott27@hotmail.com'
	},
	emailcredentials: {
		email: '',
		password: '',
		server: 'Gmail'
	}
}
