Hi I am using very simple configuration.
Receive strings from TCP input and write to a file
Sent string
This is new string 8
Written in to file
2022-09-21T12:36:28.278922Z %{host} This is new string 8
I want to avoid the timestamp and%{host} in the file
Can someone suggest. Here is my conf file?
input {
tcp {
host =\> "1.1.1.1"
port =\> 33333
codec =\> line
}
}
output {
file {
path =\> "/var/log/rajeshltrace.log"
create\_if\_deleted =\> true
flush\_interval =\> 1
codec =\> line
}

If you do not supply the format option to the line codec then [it will call](https://github.com/logstash-plugins/logstash-codec-line/blob/8036e2b0343da1ee16f9fae0a8f6f456bdb4efd1/lib/logstash/codecs/line.rb#L62) event.to\_s, which adds the timestamp and hostname. Change it to
```
codec => line { format => "%{message}" }
```

One more small query, I could see Hostname getting populated as Ip address when I use UDP but when I use TCP it is displaying as %{host}. Any clue Badger?
thanks in advance.

That suggests that when using a tcp input the [host] field does not exist. That would be strange. I would expect it to be a hash, and the output to contain "{name=1.2.3.4}", or whatever your IP is (unless the name can be looked up).
