Hi @cyberpop,

Splunk isn't a DB, so there isn't a list of fields related to an index, in other words, an index isn't a table!

So in Splunk fields extraction is ususally related to sourcetype, so you could try to see in [Settings -- Sourcetypes] if there is the list of the fields extractions, but it could be not sufficient, because if in your logs, theres something like "field=value", there's no field extraction and Splunk automatically recognize a field.

In conclusion, the only way to have the field list is to run a search like this:

index=your_index | table * | transpose | table column

Ciao.

In addition to @gcusello his comment, you can also use the '| fieldsummary' command to get a summary of all fields extracted from the events in a certain index.

index=your_index | fieldsummary
