How to Handle different Log in Clustering Openshift

Hello, so I have an openshift environment and the logs are monitored to elasticsearch. But there is one log that is of a different type. That is a JAVA-based backend log.

Can I configure it in logstash? Because if I change filebeat I'm afraid it will change to another log.

Here is the output captured in elsticsearch, sorry I have to censor because this is privacy data.

Thank you
