Hi,
I have 4 development servers:
- Webserver Apache - Filebeat
 - Integration server 1 Java-code - Filebeat
 - Integration server 2 Java-code - Filebeat
 - Payment server - .Net
 
And I have one server that runs:
- Logstash
 - Elasticsearch
 - Kibana
 
Is it ok to have Logstash on the server that runs Elasticsearch and Kibana, or should it be installed at all my development servers?
