Having Logstash reading JSON
I found out that logstash will automatically detect JSON byt using the codec field within the file input as follows:
input { stdin { type => "stdin-type" } file { type => "prodlog" # Wildcards work, here :) path => [ "/root/isaac/Mylogs/testlog.log"] codec => json }}output { stdout { debug => true } elasticsearch { embedded => true }}Then Kibana showed the fields of the JSON perfectly.
