HF is a Heavy Forwarder, a full Splunk instance that handles inputs and sends data to a Splunk Indexer
HEC - HTTP Event Collector, is a one way (among many) in which you can bring data to Splunk
in other words, HF is a machine / tool and HEC is a function of this machine / tool
HF:

HEC:

Thanks Adonio.

So am I correct to say that all HTTP/S events should be collected by HEC on HF, else, for all events other than HTTP/S, HF will do the work? is there any other function of HF to collected non-HTTP/S events?

Thanks.
