I am current trying to do a JavaScript post to Logstash by using a tcp input.
JavaScript Post
xhr = new XMLHttpRequest();
var url = "http://localhost:5043";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/json");
var data = JSON.stringify({"test" : hello});
xhr.send(data);
Logstash config file
input {
tcp {
port => 5043
}
}
filter{
}
output {
stdout {
codec => rubydebug
}
}
Output in console

I cant seem to see my json data {"test" : hello} passing into logstash could there be something wrong with my logstash.config file ? Please help
I have also tried the following :
input {
http {
port => 5043
}
}
I get the following error is broswser : XMLHttpRequest cannot load http://localhost:5043/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://test/' is therefore not allowed access.
Please guide me in the right direction as to what I need to look at ? I am very new to the ELK stack
Thanks
