| inputlookup <filename>.csv
The lookup table '<filename>.csv' requires a .csv or KV store lookup definition.
The .csv files appear on the local file system and propagate across the cluster properly. The splunkd.log also doesn't give any information beyond what the UI already outputs.
Could it be permissions? Can you see the lookup file in the lookups list? Is it private/app/global permission?
Did you create the lookup from the Add new lookup in the UI - what was the destination app?
hi @jking81
In addition to creating a lookup table by uploading the file, you'll also need to create a definition.
Under lookups, check for lookup definition option, select and configure it with the uploaded file and other field details as necessary. Once configured you should be able to search the content from the lookup file.
