===== Multi-instance =====

==== Purpose ====
  * Pro.Monitor instances can work together to distribute monitoring workload. The instance with primary role will manage the configuration and distribute tasks to the ones with agent role. A primary server can also act as an agent. A standalone Pro.Monitor instance will therefore be a primary server and an agent.

==== Configuration ====
  * Define one Pro.Monitor like a configuration server
  * Define one and more Pro.Monitor agent

A server Pro.Monitor handle the monitoring configuration. 
An agent is only a worker. He does the work give by the server.

It’s possible to create associations agent / company to force the system to be monitored by a given agent.

==== Add a new agent ====
The agent registers automatically to the server when it operates as an agent.

How to set an Pro.Monitor instance as agent

  * From the top right of the screen, click on the setting icon
  * Select the admin configuration sub-menu
  * Click on tab Multi-instance 
  * Uncheck Primary server role and check Agent
  * After 30 seconds, the agent will be visible in list agent in Pro.Monitor server instance.

The instance will then switch to agent mode only, therefore not handling a monitoring configuration anymore. 
When the agent receives a work, it asks the monitoring configuration to the server.
