Calling outputResults with a list of dictionaries will pass those events back to Splunk. When you add data to Splunk, Splunk processes it, breaking the data into individual events, timestamps them, and then stores them in an index, so that it can be later searched and analyzed. The data is parsing fine. Join us for four days of innovation, featuring today's thought leaders, Splunk's top partners, 300+ education sessions and numerous opportunities to learn new skills.
