Actuator

Actuator that simply executes the actions given as parameter

This strategy allows anyone to create an action plan with a predefined set of actions. This strategy can be used for 2 different purposes:

  • Test actions

  • Use this strategy based on an event trigger to perform some explicit task

Requirements

Metrics

None

Cluster data model

None

Actions

Default Watcher’s actions.

Planner

Default Watcher’s planner:

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.

Configuration
