I don't know what information is needed, but I've started sending syslog input into logstash (and therefore into ELK).

My input simply specifies a port, the filter contains the following:

```auto
filter {
  if [type] == "syslog" {
    grok {
      match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
      add_field => ["received_at", "%{@timestamp}"]
      add_field => ["received_from", "%{host}"]
    }
    syslog_pri {
    }
    date {
      match => ["syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]
    }
  }
}

```

I then added the following to `syslog_pri`:

```auto
    syslog_pri {
      add_field => { "[@metadata][type]" => "syslog" }
      add_field => { "[@metadata][beat]" => "syslog" }

```

Here's what the output looks like:

```auto
output {
  elasticsearch {
    hosts => ["localhost"]
    manage_template => false
    index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
    http_compression => true
    sniffing => true
    sniffing_delay => 20
  }
}

```

Neither of those syslog\_pri options seem to have helped. It doesn't have any \_grokparsefailure, but it has syslog-ish fields like facility and severity, so I assume it is being picked up and being filtered, it's just that the output index is literally the string `"%{[@metadata][beat]}-2019.05.28"`.

I left the date in to make it clear I'm not scrubbing it in any way- that's literally the index name.
