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

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(...)
