**Pending**: A number of pending tasks for this actor.
**Number of Pending Tasks**: The number of method calls for this actor that are still awaiting execution.

**Number of ObjectRefs In Scope**: The number of object refs in scope for this actor, which correspond to objects in the Ray object store. object refs
in scope will not be evicted unless object stores are full.

**kill actor**: A button to kill an actor in a cluster. It is corresponding to ``ray.kill``.
**kill actor**: A button to kill an actor in a cluster. It has the same effect as calling ``ray.kill`` on an actor handle.

**Infeasible Actor Creation**: Actor creation is infeasible when an actor
requires more resources than a Ray cluster can provide. This is depicted
as a red colored actor.
requires more resources than a Ray cluster can provide, for example an actor that requires a GPU on a cluster that has none. The actor's state is marked "Infeasible" and highlighted in red.
**Pending Actor Creation**: Actor creation is pending when there are no
available resources for this actor because they are already taken by other
