       This probe fires when the JSON data is about to be read. This probe must gather up data and then call the
       following macros to output the data in JSON format. First, @json_output_data_start must be called. That
       call is followed by one or more of the following (one call for each data item):
       @json_output_string_value, @json_output_numeric_value, @json_output_array_string_value, and
       @json_output_array_numeric_value. Finally @json_output_data_end must be called.
