Best practice: For more granular results with scripted inputs, you can increase the frequency at which the input runs using the interval setting in inputs.conf. Running the input more frequently consumes more storage, and running it less frequently uses less, which can affect license consumption. The default interval is 60 seconds. See Scripted Input in the input.conf topic of the Splunk Enterprise Admin manual.
Best practice: For all of the data inputs, specify a desired target index to provide a more sustainable practice for data access controls and retention models. By default, Splunk collects the data in the default index named main.
