=OPS635 Lab 5: Nagios Installation and Configuration=
==Overview==
In an enterprise environment, a production server must be staged before deployment. Any upgrade to the production servers must be tested in a testing environment and signed off by the change manager(s) before deploying to the production environment. In this lab, you will install and configure the Nagios monitoring framework on a VM running on your testing environment before deploying it to the production environment.
==Investigation 1: Manual Nagios Installation==
Clone your existing VM. Call the new VM nagios.<yourdomain>.ops, and provide it a static address of your choice.
* Add the necessary records for this machine to your DNS server.
* Install and configure Nagios on this machine.
* Configure your Nagios to monitor the following host(s)/service(s):
** Seneca host(s)/Service(s):
**scs.senecac.on.ca
**ict.senecacollege.ca
*If either of these services go into a hard-fail state, nagios should send you an email.
==Investigation 2: Scripted Nagios Installation==
* Clone your existing VM again. Call the new VM nagiosclone.<yourdomain>.ops, and provide it a static address of your choice.
* It is not necessary to add this machine to your DNS service.
* Write a script to automate the nagios configuration process you used in Investigation 1
* Test the script to ensure it will automatically configure a newly installed machine as a nagios server.
==Submission==
Demonstrate the your script working on a newly installed VM, and upload it to blackboard.
