temporal task-queue describe [command options] [arguments...]

   The Server records the last time of each poll request. Poll requests can last up to a minute, so a LastAccessTime under a minute is normal. If it's over a minute, then likely either the Worker is at capacity (all Workflow and Activity slots are full) or it has shut down. Once it has been 5 minutes since the last poll request, the Worker is removed from the list.
