Introduction

opHA introduces the concept of a Primary & pollers multiple Poller servers:

• The Primary is the node server that have keeps the information of all the pollers and it is where we can read all the information from.
• The pollersPollers, collect their own data, and send that information to the Primary when it is requested. 

The process of synchronising the information of the nodes is made by the Primary. The Primary requests the information for each poller with pull requests. 

The first time the pull script runs, it is going to request requests all the data for each configured poller. Next time, it is going to request requests only the modified data since the last synchronisation.
