Status information can also be requested in JSON format. The content of the information is identical, only the representation of the information is different, formatted in a JSON wrapper object, with one key/value pair for each field in the standard status output.
Examples of the JSON output for each status output are provided below. For more information on the fields displayed, see Section E.2, “Generated Field Reference”.
