Website Monitor - Ruby Script

Simple Ruby Script file to check the web site and post an email using gmail service.

This script contains 2 main parts

1. Checking website - for response OK and content
2. Email to admin on failure [using gmail]

Checking Website:

    url = URI.parse(web_url)

  net_conn = Net::HTTP.new(url.host, url.port)

  net_conn.use_ssl = url.scheme == "https"

  res = net_conn.get('/')

   We can check res.code == 200 and verify res.body includes the content we wanted to see.

Email [Using gmail]

  NOTE: Gmail needs TLS encryption; so enable it before start sending msg

   

    smtp = Net::SMTP.new("smtp.gmail.com", 587)

    smtp.enable_starttls #gmail needs this encryption

    smtp.start("DOMAIN_FILLER", <gmail_acc>, <gmail_pwd>, :login)  do |s| 

      s.send_message(<msg>, <gmail_acc>, <to>)

    end  

  Sample GMAIL Msg format:

   msg = [

    "From: WebMonitor <from_addr>",

    "To: Admin <to_addr>",

    "Subject: <subject>",

    "",

    "Hi,",

    "!!MORE DETAILED MSG!!"

  ].join("\r\n");
