Can anyone let me know how to extract fields in Splunk ? I have one sourcetype file that contains data of Attacker Address , Device Address , Device Vendor and Device Product . These fields are not the regular and interesting fields .
Want to extract these fields so that i may use them during search to obtain the desired results .
Here is our documentation on extracting fields https://docs.splunk.com/Documentation/Splunk/latest/Scenarios/Extractfields. This goes over how to use our field extraction tool in Splunk to extract the fields you want from the data.
If you are good with regex you can use the rex command in Splunk's search language to temporarily extract fields with regex http://docs.splunk.com/Documentation/Splunk/latest/SearchReference/Rex. You can then save the regex you used with that command as a field extraction by going to settings > Fields > Field extrations and saving it there.
Here is some more documentation you might find useful https://docs.splunk.com/Documentation/Splunk/6.5.1/Search/Extractfieldswithsearchcommands
