Hi all, mb its stupid idei, but i want monitoring postfix queue .  
I write in file "data", "hostname", "count", how can I transfer this data to elastic?  
at the moment, i am parse postfix logs, thanks to [GitHub - whyscream/postfix-grok-patterns: Logstash configuration and grok patterns for parsing postfix](https://github.com/whyscream/postfix-grok-patterns).  
And i add in filter logstash

```auto
filter {
    grok {
          match => { "message" => "%{SYSLOGTIMESTAMP:timestamp} %{SYSLOGHOST} %{DATA:program}(?:\[%{POSINT}\])?: %{GREEDYDATA:message}" }
          match => { "message" => "%{SYSLOGTIMESTAMP:timestamp} %{HOSTNAME} %{NUMBER:postfix_queue}" }
          overwrite => ["timestamp", "message"]
   }

```

`match => { "message" => "%{SYSLOGTIMESTAMP:timestamp} %{HOSTNAME} %{NUMBER:postfix_queue}" }`  
add in filebeat.yml  
` - /var/log/postfix_queue.log`  
I understand that now need to create a new field in the postfix\_queue index?
