I want to know if its possible to search based on input from a dynamic list. Either a lookup table or csv file. I have a requirement to search an index for specific behaviour of a particular user. The user list is mostly static but will be updated when new users are added/removed. Is this possible in graylog? I looked into inputs like the json path or plaintext tcp but I can’t see any functionality to feed the results of one search into another. Does this functionality exist in community graylog 2.x-3.x?
