I have a log file in which all the events has this below lines as common;
04:03:28 04/12/2016 good 201961028 1456 - Validation_Competed - ProductCode_3446565 0.133 sec, 1 row, 0 5:75127 200 04:03:32 04/12/2016 bad 201961028 1456 - Validation_Competed - ProductCode_3446569 0.133 sec, 1 row, 0 5:75127 200
Here in the above 2 events we have the words "good" and "bad" and I need to a create a new field by name "STATUS" for them which should have its values as either "good" or "bad".
Can some one please advise me the right REX command to execute here?
Field Extraction (saved) from Splunk Web
Field Extraction from conf files editing
Interactive field extraction from Search page
Inline field extractions using rex
This is a simple log format and rex should be fairly easy to extract the field you are interested and as suggested above.
If you not comfortable with rex , I would suggest to use the splunk field extractor utility and create the required field first during search time and then you can use the newly created field in your search .
See below documentation for more details .
So the simplest answer of course is
... | rex "(?<STATUS>good|bad)" this assumes however that neither good nor bad show up in your events other than the status field and your status field only takes the values of good and bad.
You could anchor the regular expression based on the date format outside of the capturing group. You'd want to play with samples of your data and a site like regex101.com to develop expressions. Eventually you could build a field extraction for your sourcetype and not need the Rex command in your search.
