Inputting file into logstash

Hi,

I have here a software (NetWtiness) that generates logs in the extension .nwmdb, and I've been trying to use it as input to Logstash to visualize it in Kibana.
This .nwmdb file is not human readable.
Should I use filebeat? Logstash? Do I have to convert the file?
Please, any guidance would be appreciated.
Thank you.

It sounds like you have to convert the files outside of Logstash or write a Logstash input plugin to process them.
