I'm working on a report that uses lot of fields. I would be extracting those fields across many sourcetypes. I have my personal username in splunk. This question just struck me,
"What is the default visibility of extracted fields?"
Is is visible to all other users also? If it is, it's better that I delete the one time use extractions so as not to clutter Splunk.
By default, your field extractions are private, if you created them using the Manager or the Interactive Field Extractor. You can change that selectively by going to Manager -> Fields.
Still, if they are one-time-use, you might want to delete them.
And perhaps a better alternative in the future is to use the rex command, which creates field extractions on the fly. The fields created by the rex command are not saved.
