   The goal is to
   
  -* install the LAMP stack on your nervios instance
  -* install the Nagios server on your nervios instance
  +* install the LAMP stack on your nerviosXX instance
  +* install the Nagios server on your nerviosXX instance
   * configure Nagios to monitor servers in the pipeline
   * confirm that the pipeline is being monitored
   * test monitoring by halting one or more servers and observing the result
  -* expand monitoring to cover Apache Tomcat on the caraxx server, and Jenkins on hombrosxx..
  +* expand monitoring to cover Apache Tomcat on the cara1 server, and Jenkins on hombros1.
   * test the expanded monitoring
  +
  +NOTE: As of Spring 2017, due to server capacity issues, this lab will have many nerviosXX servers monitoring the main pipeline. Do not launch your own caraXX servers.
   
   === Steps
   WARNING: READ THIS ENTIRE LAB CAREFULLY BEFORE STARTING. IF YOU JUST LAUNCH INTO THE STEP BY STEP INSTRUCTIONS YOU WILL REGRET IT WHEN YOU GET A FEW PARAGRAPHS FURTHER. BE SURE YOU UNDERSTAND EVERYTHING.
  
positive.code: 
  Take a screen shot and post to Slack.
  
  Test that your monitoring is working correctly by exiting your VM and issuing:
  
   vagrant suspend caraXX
  
  replacing the XX as appropriate for your team.

  In the http://www.unixmen.com/install-configure-nagios-4-ubuntu-14-1014-04/[Unixmen instructions], in the section "*Configure Monitoring Targets*," there is a small choice you can make, whether to put in the ip address of nerviosxx, or the actual hostname nerviosxx. Reading the notes in the configuration file, what do you think you should do? Will putting in the nerviosxx host name work? How can you find out?
  
  NOTE: I am giving you what not how at this point, follow the instructions carefully and be careful of the address you use. If you give something a default host name of "client," that is what you will see in the console. Notice that host_name is not the same as address in the Nagios configuration.
