actor_id: str#: The id of the actor.

class_name: str#: The class name of the actor.

state: Literal['DEPENDENCIES_UNREADY', 'PENDING_CREATION', 'ALIVE', 'RESTARTING', 'DEAD']#

The state of the actor.

DEPENDENCIES_UNREADY: Actor is waiting for dependency to be ready. E.g., a new actor is waiting for object ref that’s created from other remote task.
PENDING_CREATION: Actor’s dependency is ready, but it is not created yet. It could be because there are not enough resources, too many actor entries in the scheduler queue, or the actor creation is slow (e.g., slow runtime environment creation, slow worker startup, or etc.).
ALIVE: The actor is created, and it is alive.
RESTARTING: The actor is dead, and it is restarting. It is equivalent to PENDING_CREATION, but means the actor was dead more than once.
DEAD: The actor is permanatly dead.

job_id: str#: The job id of this actor.

name: str | None#: The name of the actor given by the name argument.

node_id: str | None#: The node id of this actor. If the actor is restarting, it could be the node id of the dead actor (and it will be re-updated when the actor is successfully restarted).

pid: int | None#: The pid of the actor. 0 if it is not created yet.

ray_namespace: str | None#: The namespace of the actor.

serialized_runtime_env: str | None = None#: The runtime environment information of the actor.

required_resources: dict | None = None#: The resource requirement of the actor.

death_cause: dict | None = None#: Actor’s death information in detail. None if the actor is not dead yet.

is_detached: bool | None = None#: True if the actor is detached. False otherwise.

placement_group_id: str | None = None#: The placement group id that’s associated with this actor.

repr_name: str | None = None#: Actor’s repr name if a customized __repr__ method exists, else empty string.

num_restarts: int = None#: Number of restarts that has been tried on this actor.

num_restarts_due_to_lineage_reconstruction: int = None#: Number of times this actor is restarted due to lineage reconstructions.
