  being consumed by a monitoring tool, rather than intended for human
  
negative.code: 
  When appending `?pretty=true` to any request made, the JSON returned
  will be pretty formatted (use it for debugging only!). Another option is
  to set `?format=yaml` which will cause the result to be returned in the
  (sometimes) more readable yaml format.
