A PhantomJS script to monitor Ellucian Student Planning / Self-Service for unresponsiveness. A PowerShell script to run the PhantomJS script and recycle the app pool, send an email.

check_student_planning.js

/*
  Student Planning goes down randomly and we have to recycle the app pool to fix it.
  This script will try to login to Student Planning and make an AJAX request.  It will
  return text output (console.log() output) about whether it is working or not.
  
  NOTE: this script relies on PhatomJS, which you can download here: 
  http://phantomjs.org/download.html
  
  NOTE: change the values of the host, user, and pass variables. Optionally change the timeout variable.

# This script will call a PhantomJS script
# to test out that Student Planning is responding to AJAX requests.
# If there is a problem with the AJAX request, this script will notify
# via Email and attempt to recycle the app pool.

# NOTE: This script should be on the same machine hosting Student Planning / Self-Service.

# NOTE: This script must be run with administrator priviledges in order to recycle the app pool.

# NOTE: This script is intended to run periodically on the Task Scheduler

# NOTE: change the values of the following variables
#       * $appPool
#       * $result (use correct path to PhantomJS and the check_student_planning.js file)
#       * $to
#       * $body (change the value of yourschool.edu domain)

# NOTE: change the -SmtpServer parameter in the Send-MailMessage command
