The watcher.decision_engine.planner.weight Module¶

class watcher.decision_engine.planner.weight.WeightPlanner(config)[source]¶

Bases: watcher.decision_engine.planner.base.BasePlanner

Weight planner implementation

This implementation builds actions with parents in accordance with weights. Set of actions having a higher weight will be scheduled before the other ones. There are two config options to configure: action_weights and parallelization.

Limitations

• This planner requires to have action_weights and parallelization configs tuned well.

static chunkify(lst, n)[source]¶

Yield successive n-sized chunks from lst.

compute_action_graph(sorted_weighted_actions)[source]¶

create_action_plan(context, audit_id, solution)[source]¶

create_scheduled_actions(graph)[source]¶

classmethod get_config_opts()[source]¶

Defines the configuration options to be associated to this loadable

Returns:	A list of configuration options relative to this Loadable
Return type:	list of oslo_config.cfg.Opt instances

get_sorted_actions_by_weight(context, action_plan, solution)[source]¶

schedule(context, audit_id, solution)[source]¶

The planner receives a solution to schedule

Parameters:	solution (BaseSolution subclass instance) – A solution provided by a strategy for scheduling audit_uuid (str) – the audit uuid
Returns:	Action plan with an ordered sequence of actions such that all security, dependency, and performance requirements are met.
Return type:	watcher.objects.ActionPlan instance
