Logstash - Reference JSON files in a folder

Trying to get a configuration going in Logstash where I can reference multiple JSON files from a folder and have it process them accordingly -- not sure if this is at all the correct way to go about this, here is what I have so far

input {
syslog {
port => 514
codec => "json"
}
}

filter {
path => "/home/*.json" ]
}
}

output {
if [codec] == "json" {
elasticsearch {
hosts => "IP:9200"
http_compression => "true"
index => "testjson-%{+YYYY.MM.dd}"
}
}

I would start off with this:

input {
    file {
        path => "/tmp/foo/*.json"
        sincedb_path => "/dev/null"
        mode => "read"
        codec => multiline { pattern => "^Spalanzani" negate => true what => "previous" auto_flush_interval => 2 }
        file_completed_action => "log"
        file_completed_log_path => "/dev/null"
    }
}
filter { json { source => "message" } }
output { stdout { codec => rubydebug } }

You need to read up on what those options on the file input are doing.
