go ship logs to ELK flow

Shipping Golang logs with ELKB stack

Goal of this blog In this blog, I am going to show you how easily we can write logs to the files in Golang. As well as we are going to store all logs on elasticsearch with EKB (Elasticsearch, Kibana, Beats). Why ELKB stack ?

It is very difficult to go to each server and check all log files in case of debugging or to generate any insights or reporting. ...
