State CLI allows users to access the state of various resources (e.g., actor, task, object).

.. click:: ray.experimental.state.state_cli:task_summary
   :prog: ray summary tasks

.. click:: ray.experimental.state.state_cli:actor_summary
   :prog: ray summary actors

.. click:: ray.experimental.state.state_cli:object_summary
   :prog: ray summary objects

.. click:: ray.experimental.state.state_cli:list
   :prog: ray list

.. click:: ray.experimental.state.state_cli:get
   :prog: ray get

.. _ray-logs-api-doc:

Log CLI
-------

Log CLI allows users to access the log from the cluster. 
Note that only the logs from alive nodes are available through this API.

.. click:: ray.scripts.scripts:ray_logs
    :prog: ray logs
