Limitations
|

-----------
|
||||
|
||||
* The plugin version 1.0.0 provides coordination only for Agent Central service.
|
||||
* The plugin version 1.0-1.0.0-1 provides coordination only for Agent Central service.
|
||||
Alarm evaluator and Notification agent will be supported in the next plugin
|
||||
version.
|
||||
|
||||
* The plugin works correctly only on clouds with odd numbers of controllers.
|
||||
This requirement is mandatory because Redis needs an odd number of nodes to
|
||||
choose the master successfully.
