List of pretrained source types

Splunk software ships with built-in or pretrained source types that it uses to parse incoming data into events.

The Splunk platform can automatically recognize and assign many of these pretrained source types to incoming data. You can also manually assign pretrained source types that the Splunk platform doesn't recognize automatically. To assign source types manually, see Override automatic source type assignment.

From a heavy or universal forwarder, you can also configure source types from the inputs.conf configuration file. If you use Splunk Enterprise, you can assign source types from either Splunk Web or from the inputs.conf file.

Use a pretrained source type if it matches your data, as the Splunk platform already knows how to properly index pretrained source types. If your data doesn't fit any pretrained source types, you can create your own source types. See Create source types. The Splunk platform can also index virtually any format of data even without custom properties.

Special source types

The following table shows the special source types:

Source type	Origin	Examples
known_binary	The file name matches a pattern generally known as that of a binary file, not a log file	MP3 files, images, .rdf files, .dat files, and other obvious non-text files

Miscellaneous	snort, splunk_disk_objects*, splunk_resource_usage*, kvstore*

The source types marked with an asterisk ( * ) use the INDEXED_EXTRACTIONS attribute, which sets other attributes in props.conf to specific defaults and requires special handling to forward to another Splunk platform instance. See Forward fields extracted from structured data files.

Learn a source type configuration

To find out what configuration information the Splunk platform uses to index a given source type, you can use the btool utility to show the properties on your forwarder. If you use Splunk Enterprise, you can do this on your Splunk Enterprise instance.

For more information on using btool, refer to Use btool to troubleshoot configurations in the Troubleshooting Manual.

The following example shows how to list out the configuration for the tcp source type:

$ ./splunk btool props list tcp
