nornir.core.processor

class nornir.core.processor.Processor(\args, **kwargs*)

This defines the Processor interface. A processor plugin needs to implement each method with the same exact signature. It’s not necessary to subclass it.

A processor is a plugin that gets called when certain events happen.

• subtask_instance_completed(task: nornir.core.task.Task, host: nornir.core.inventory.Host, result: nornir.core.task.MultiResult) → None

  This method is called when a host completes executing a subtask

• subtask_instance_started(task: nornir.core.task.Task, host: nornir.core.inventory.Host) → None

  This method is called before a host starts executing a subtask

• task_completed(task: nornir.core.task.Task, result: nornir.core.task.AggregatedResult) → None

  This method is called when all the hosts have completed executing their respective task

• task_instance_completed(task: nornir.core.task.Task, host: nornir.core.inventory.Host, result: nornir.core.task.MultiResult) → None

  This method is called when a host completes its instance of a task

• task_instance_started(task: nornir.core.task.Task, host: nornir.core.inventory.Host) → None

  This method is called before a host starts executing its instance of the task

• task_started(task: nornir.core.task.Task) → None

  This method is called right before starting the task

class nornir.core.processor.Processors

Processors is a wrapper class that holds a list of Processor. Each method will just iterate over all the the Processor objects in self and call its method. For instance:

>>>    def my_method(...):
>>>        for p in self:
>>>            p.my_method(...)

• subtask_instance_completed(task: nornir.core.task.Task, host: nornir.core.inventory.Host, result: nornir.core.task.MultiResult) → None

• subtask_instance_started(task: nornir.core.task.Task, host: nornir.core.inventory.Host) → None

• task_completed(task: nornir.core.task.Task, result: nornir.core.task.AggregatedResult) → None

• task_instance_completed(task: nornir.core.task.Task, host: nornir.core.inventory.Host, result: nornir.core.task.MultiResult) → None

• task_instance_started(task: nornir.core.task.Task, host: nornir.core.inventory.Host) → None

• task_started(task: nornir.core.task.Task) → None
