Hello,

I was wondering if there is a way to configure logstash as following:

- Java application sends a longer XML file by OutputStream to Logstash.
- Logstash "listens" over this outStream to receive, process and store it in ElasticSearch.

Many thanks.

Regards,  
Paco.

You mean something to transform XML to JSON (what elasticsearch speaks)?

I think you can try this filter:

[https://www.elastic.co/guide/en/logstash/current/plugins-filters-xml.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-xml.html)

It should do the job!

Many thanks ebuildy,

No, I mean to be "listening" from Logstash any event in a opened OutputStream in Java. I don't want to read from Files, I want to read from outputStream that comes from Java -\> Get it by Logstash -\> Process it by XML plugin (as you told me before) -\> Store it by ElasticSearch.

So, my question is about the first "connection": between my Java application and Logstash input plugin, if there is a plugin which reads streams from a Java Application.

Many thanks.

Regards,  
Paco.

Logstash has some input plugins:

- TCP
- HTTP
- UDP
- RabbitMQ
- File

And filter

- XML

And output:

- ElasticSearch

From your Java, you can communicate with LogStash via TCP or HTTP easily I am sure. If you want HA, use a queue like RabbitMQ or Kafka between Java and LogStash.
