Extracting field

Gayathirik — Fri, 12 Aug 2016 10:23:02 GMT

I tried to extract a particular field from my input data , for ex: src_ip
However, those fields are not showing on the Fields Sidebar. Though I can view them in the Manager>>Fields>>Field Extractions.

By any chance, are you running in fast mode?

If so then this turns field discovery off and the fields are not available. If you run in smart/verbose mode then field discovery is on and you can see your fields

If you are running in smart/verbose mode then I would suggest that you need to specify the sourcetype to get that field to appear. The fields are relative to sourcetype, so if your sourcetype isn't showing up then your field won't show up

Few things to check

1) Search mode: Make sure you're running your searches in Smart or Verbose and not Fast
2) The fields will show only if more than 20% of the events have that field. Try add | table src_ip to your search to see if it returns any results
3) Permissions on the field. Make sure everyone has "read" permissions
