The programmer never has to work with these types explicitly. Each type of task

.. _common-show-commands:
.. clicmd:: show thread cpu [r|w|t|e|x]
.. clicmd:: show event cpu [r|w|t|e|x]
This command displays system run statistics for all the different event
types. If no options is specified all different run types are displayed
together. Additionally you can ask to look at (r)ead, (w)rite, (t)imer,
(e)vent and e(x)ecute thread event types.
.. clicmd:: show thread poll
.. clicmd:: show event poll
This command displays FRR's poll data. It allows a glimpse into how
we are setting each individual fd for the poll command at that point
in time.
.. clicmd:: show thread timers
.. clicmd:: show event timers
This command displays FRR's timer data for timers that will pop in
the future.
