We are migrating to the cloud and we are using AWS Kinesis to ingest log data from our servers. The Splunk Add-On comes with pre built sourcetypes like aws:firehose:text. Raw data is supposed to feed through this sourcetype however I do not want all of my sourcetypes coming from windows, linux, marklogic etc to read aws:firehose:text as the sourcetype. How do I modify this? Is any documentation out that explains this? The sourcetypes are required since kinesis uses HEC to connect and send data. If I modify the sourcetype at the indexer after it has passed the HEC, will this work?
