NAME¶
probe::json_data - Fires whenever JSON data is wanted by a reader.
CONTEXT¶
This probe fires when the JSON data is about to be read. This probe must gather

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.
