What is the best way to integrate more than one collection of mongodb into Kibana via Logstash and Elasticsearch. I tried below 2 options but can't see all fields in Kibana. Because of that I am not able to join 4 collections.
Option1 - In single configuration file (Logstash) I combined all 4 collections.
Option2 - Create separate 4 Indices and in Kibana combine all 4 Indices to create single Indices
Highly appreciate if anyone has any other solution.
