In the Splunk Architeture, it is known that Splunk has major 3 components.
1. Forwarder - Instance installed at the log collection devices
2. Indexer - Virtual Instance installed with SPLUNK for parsing the collected logs
3. Search Head - Not very clear about where do we have it. Can somebody explain in non-technical words, what is a Search Head and Where can we find it?
Search Head is the one which we use for searching the logs from indexer...
Basically the Full Splunk instance can act as Heavy Forwarder/Indexer/Search head...its just a configuration due to which it acts different.
