I have a few question about moint configuration

I have a few questions after following this guide https://www.digitalocean.com/community/tutorials/lemp-stack-monitoring-with-monit-on-ubuntu-14-04

The below code indicates the website on port 80 & the non www version of the domain

check process nginx with pidfile /var/run/nginx.pid
    group www-data
    start program = "/etc/init.d/nginx start"
    stop program = "/etc/init.d/nginx stop"
    if failed host example.com port 80 protocol http then restart
    if 5 restarts within 5 cycles then timeout

As a newbie my questions are: since my website is running on port 443 and I am using the www version:

1 - Should I change from port 80 to 443 since I am using https? 2 - Should I change from example.com to www.example.com or https:www.example.com, because I am using the www version?
