Cluster Object Wrapper

Watcher Decision Engine must provide a way to get cluster objects that can be used directly within a Strategy . These objects will be refreshed periodically.

Persistent Audit Param

Watcher Policies

Admin can use policies to allow or not users to invoke Watcher API methods.

Nova Policies

Dynamic Action Desc

‘Watcher Decision Engine’_ must support Strategy with new customized actions.

Uniform Airflow Strategy

This Strategy trigger migration of VMs based on the airflow of servers. This strategy makes decisions to migrate VMs to make the airflow uniform.

Overload Strategy

This ‘Strategy’_ chooses the pair VM:dest_host that minimizes the standard deviation in a cluster best.

Plugins parameters

Watcher must give the possibility to the developer to add some parameters depending on the configuration of OpenStack cluster on the plugins

Get Goal from Strategy
