Logstash file input mix up

[logben]

Hello!

I read two Windows file shares with DNS logs with the following two seperate configuration files:

DNS-Server 1:

input {
        file {
              path => "/var/log/logstash/dns-share-pdc/dns.log"
              tags => "dns"
              mode => "tail"
              sincedb_path => "/var/log/logstash/dns-pdc-log"
             }
}

filter { if "dns" in [tags] {
       if [message] =~ /^\r/ {
       drop {}
       }

       mutate { gsub => [
                        "message", "\s\(\d+\)", " ",
                        "message", "\(\d+\)\r", "\r" ,
                        "message", "\(\d+\)", "."
                        ]
              }
       }

}

output {
if "dns" in [tags] {
      file {
           path => "/var/log/logstash/dns-import/pdc/pdc-dns-%{+YYYY-MM-dd}.log"
          
      }
   }
}

DNS-Server 2:

input {
        file {
              path => "/var/log/logstash/dns-share-gdc/dns.log"
              tags => "dns"
              mode => "tail"
              sincedb_path => "/var/log/logstash/dns-gdc-log"
             }
}

filter { if "dns" in [tags] {
       if [message] =~ /^\r/ {
       drop {}
       }

       mutate { gsub => [
                        "message", "\s\(\d+\)", " ",
                        "message", "\(\d+\)\r", "\r" ,
                        "message", "\(\d+\)", "."
                        ]
              }
       }
}
output {
if "dns" in [tags] {

      file {
           path => "/var/log/logstash/dns-import/gdc/gdc-dns-%{+YYYY-MM-dd}.log"
      }
  }
}

Server 1 works fine, but the strange thing is, that instead of getting the logs of Server 2 as configured above, I get a copy of the logs of Server 1 in the output file of Server 2. Yes, I have double checked the mounted Windows file shares. I did not mount two times the same share by accident. What is causing the mix up? Thanks in advance!

Cheers, Ben
