```auto
input {

  file {
		path => "C:/Users/user/Documents/Logstash/mylogs/spa2.log"
		start_position => "beginning"    
  }
}
filter {
  if "SPAHGW:31 32 30 30 :004:: 1200" in [message] {
    grok {
      match => { "message" => "^SPAHGW:31 32 30 30 :004:: 1200 %{GREEDYDATA:start_message}" }
    }
  }
  
  if "SPAHGW:39 39 :032:: 99" in [message] {
    grok {
      match => { "message" => "^SPAHGW:39 39 :032:: 99 %{GREEDYDATA:end_message}" }
    }
  }
}

```

Im trying to ingest logs from this line SPAHGW:31 32 30 30 :004:: 1200
