Actuator
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¶
Strategy parameters are:
| parameter | type | default Value | description |
|---|---|---|---|
actions |
array | None | Actions to be executed. |
The elements of actions array are:
| parameter | type | default Value | description |
|---|---|---|---|
action_type |

resource_id |
string | None | Resource_id of the action. |
input_parameters |
object | None | Input_parameters of the action(mandatory). |
Efficacy Indicator¶

Algorithm¶
This strategy create an action plan with a predefined set of actions.
