I have an existing index that contains a "Request" type with namely an attribute with the IP of the user. That index holds several millions of documents. I'd like to use Kibana to get some stats about the traffic to that service.
The index is updated by some custom code, it is not related to logstash in any way. I've followed this article that explains how to do it with logstash but I am wondering if it would be possible to apply the same pattern to an existing index.
Ideally, I'd like a background process to run on my index and add the geolocation information based on the IP. Is there some documentation or some plugin that would do that?
