Release notes
New Features
* Added a standard way to both declare and fetch configuration
options so that whenever the administrator generates the Watcher
configuration sample file, it contains the configuration options of
the plugins that are currently available.
* Added a generic scoring engine module, which will standarize
interactions with scoring engines through the common API. It is
possible to use the scoring engine by different Strategies, which
improve the code and data model re-use.
* Added an in-memory cache of the cluster model built up and kept
fresh via notifications from services of interest in addition to
periodic syncing logic.
* Added a way to add a new action without having to amend the source
code of the default planner.
* Added a way to create periodic audit to be able to optimize
continuously the cloud infrastructure.
* Added a way to compare the efficacy of different strategies for a
give optimization goal.
* Added a way to return the of available goals depending on which
strategies have been deployed on the node where the decison engine
is running.
* Allow decision engine to pass strategy parameters, like
optimization threshold, to selected strategy, also strategy to
provide parameters info to end user.
* Copy all audit templates parameters into audit instead of having a
reference to the audit template.
* Added a strategy that monitors if there is a higher load on some
hosts compared to other hosts in the cluster and re-balances the
work across hosts to minimize the standard deviation of the loads in
the cluster.
* Added a new strategy based on the airflow of servers. This
strategy makes decisions to migrate VMs to make the airflow uniform.
* Added policies to handle user rights to access Watcher API.
* Added a strategy based on the VM workloads of hypervisors. This
strategy makes decisions to migrate workloads to make the total VM
workloads of each hypervisor balanced, when the total VM workloads
of hypervisor reaches threshold.
