I am encountering a problem in lookups. The problem is that whenever the lookup file gets updated with new data, SPLUNK does not recognise the fields from the older data.
older file had
New one has
and we do search for RNC02, is does not find the field description containing 3G-000-001
So, is there any way to bind the lookup with the data itself so as to keep the historical data consistent.
The lookup file gets ftped through a cron job every day.
How is your lookup file being populated? If you are using the outputlookup command you can append new data so the older data is not lost
| outputlookup somefile.csv append=t
