There are several advantages to defining your own data types:The datamodel command does not take advantage of a datamodel's acceleration (but as mcronkrite pointed out above, it's useful for testing CIM mappings), whereas both the pivot and tstats command can use a datamodel's acceleration. Community; Community; Getting Started. Example 1: This command counts the number of events in the "HTTP Requests" object in the "Tutorial" data model. Splunk was founded in 2003 with one goal in mind: making sense of machine-generated log data, and the need for Splunk expertise has increased ever since.
