What part are you having trouble understanding? The syntax for the index template? What the point of the template even is? Something else? ---

I have a set of log files that contain a json that I'll have to analyze. I managed to extract the interest json correctly from the document. Now I would like to create with logstash a mapping for this json. Maybe, should I use something like that? ``` elasticsearch { index => "log-%{+YYYY.MM.dd}" document_type => "json_log" # manage_template => true # template => "E:\Programmi\logstash\bin\elasticsearch-template.json" # template_overwrite => "true" codec => json ``` could it be correct this? what do I have to write in the file? i dont understand con you make a little example for my json thanks ---

Sorry, but this is exactly what the blog post you linked to covers. If you don't understand that text and can't ask specific questions I don't think I'm able to help. ---
