Logstash configuration: for journalbeat from multiple servers

Elastic Stack Logstash
1

Hi there, I've been trying to collect logs, using journalbeat from multiple servers onto a single logstash server. I already have winlogbeat on my windows server which is using 5044, hence other servers with journalbeat are on 5045. It throws following error:

Error: Cannot assign requested address
Exception: Java::JavaNet::BindException

here is my logstash conf file. I don't understand how do I differentiate these logs/indices between server1 & server2.
@magnusbaeck could you please suggest

input {

beats {
     port => "5044"
     tags => ["windows-server"]
}
  beats {
     port => "5045"
     tags => ["server1"]
}
  beats {
     port => "5045"
     tags => ["server2"]
}

}

output {

 if "windows-server" in [tags] {
                elasticsearch {
                        hosts => ["ip of elasticsearch:9200"]
                        manage_template => false
                        index => "windowslogs-%{+YYYY.MM.dd}"
                        user => "elastic"
                        password => "password"
                 }
}
    if "server1" in [tags] {
                elasticsearch {
                        hosts => ["ip of elasticsearch:9200"]
                        manage_template => false
                        index => "server1logs-%{+YYYY.MM.dd}"
                        user => "elastic"
                        password => "password"
                 }
}

    if "sever2" in [tags] {
                elasticsearch {
                        hosts => ["ip of elasticsearch:9200"]
                        manage_template => false
                        index => "server2logs-%{+YYYY.MM.dd}"
                        user => "elastic"
                        password => "password"
                 }
}

}

You cannot have two beats inputs listening on the same port (5045). The beats will add fields to the events that identify which host they are coming from.

Is it possible then to filter by hosts but on the same port? I might need to add more servers to this configuration. Or (Directing to different ports would only help?) what could be a better solution to this? please suggest.

You could use a different port for each source server and add tags to differentiate them, but there is no need to do that because the beats add fields that differentiate them.

Thanks for your prompt response::slightly_smiling_face:
Could you please give an example for my better understanding.

In journalbeat, I've put _SYSLOG_IDENTIFIER in include matches section
