What is the HEC?

The Splunk HEC is a useful and commonly used part of Splunk. The HEC does the important function of collecting and sending HTTP and HTTPS events to other systems. One common example where the HEC adds tremendous value is by capturing/sending events from/to web and mobile-based client devices. Once Splunk captures the data via the HEC from the application, it can be used for a variety of analyses related to application use and errors.
