Use it to generate all graphs at once – It is highly recommended  to use this task as a cronjob to avoid extremely long page generation times of host and service detail views.

Sample output:

Some replies of ScopePort users I am very happy about:

Cheers, it looks great, can’t wait to deploy it myself

WOW! Very slick, easy to navigate, great colors, very professional looking app

Clear and professional web interface! very nice work! Did you do all the CSS working as well? very cool one. I can’t wait to test the server side and see how much customized alerts that I can setup. Plus the graph looks very good

I like to know when the app is ready for beta testing, we have looked at allot of apps, yours has allot of potential to meet our needs.

I just wanted to say that the ScopePort project is looking great.

Finding a service near you

An emergency in detail view

ActionMailer::Base.smtp_settings = {
  :address => "smtp.gmail.com",
  :port => 587,
  :domain => "domain.com",
  :user_name => "user@domain.com",
  :password => "password",
  :authentication => :plain
}

ScopePort already has a Email settings part in the setup section where all the required SMTP settings are stored. I wanted to fetch the SMTP configuration from the database to avoid double configuration. I stumbled over this blog post after a while: http://broadcast.oreilly.com/2009/03/using-multiple-smtp-accounts-w.html Based on this I developed the following dynamic way to define the SMTP settings:

class EmergencyMailer < ActionMailer::Base   
  def load_settings
    @@smtp_settings = {
      :address => Setting.first.mail_server,
      :port => Setting.first.mail_port,
      :domain => Setting.first.mail_hostname,
      :authentication => :plain,
      :user_name => Setting.first.mail_user,
      :password =>Setting.first.mail_pass
    }
  end
 
  def emergency_notification(emergency, email)
    load_settings
    recipients  email
    from        Setting.first.mail_from
    subject     "[ScopePort] An emergency has been declared!"
    sent_on     Time.now
    body        :emergency => emergency
  end
end

The method load_settings gets called by the delivery method and fills the smtp_settings instance variable with parameters from the database.
