title: Nagios script to check Nagios
body: <p>I am currently running multiple (6) Nagios instances across multiple projects. My concept is to run one Nagios instance per project, each responsible for the machines below them and with project specific tasks.</p>
  
  <p>Yes, I could roll all of these into one Nagios instance but this is not the question.</p>
  
  <p>I have checked Google and Nagios Exchange looking for a plugin and if there is nothing out there I will build one myself. I want to know if anyone has any experience with this.</p>
  
  <p>Question:
  Is there a Nagios plugin which will check the overall status of another remote Nagios instance, either through NRPE and a local script, or over authenticated HTTP(s) to the cgi-bin, simply reporting on how many are OK / Warning / Critical / Unknown, etc in each checked instance. HTTP(s) would be preferred.</p>
  
  <p>If not, can someone point me in the direction of how to query and understand the responses of a single Nagios instance. If there is not any existing plugins I will start looking at Nagstamon for guidance on how to achieve this.</p>
