Before the HTTP Event Collector can accept your data for indexing, you must authenticate to the Splunk Cloud Platform or Splunk Enterprise instance on which it runs. Even data distribution on indexers required for search performance at scale •Sending ”514” traffic to just one indexer works in only the smallest of deployments •UDP load balancing typically trickier than TCP Syslog is a protocol–not a sourcetype •Syslog typically carries multiple sourcetypes •Sourcetypes are essential for “Schema on the Fly” new to Splunk and its ecosystem I was asked to research it a bit and try to inject data in 2 ways: local file and using REST Api I added local CSV file data to the Splunk Cloud from the "Add data --> Upload" option.
