So I want to basically do a string split at the " . " in one of my outputs from a log file (It is an IP address). Is there any way to do this with a Logstash filter? It would make the requests from my application to my server generate much less garbage when I call the server.

This configuration:
```auto
input { stdin {} }
filter {
mutate { split => { "message" => "." } }
mutate { convert => { "message" => "integer" } }
}
output { stdout { codec => rubydebug } }
```
Will result in this output, if fed `172.19.73.1` as STDIN:
```auto
172.19.73.1
{
"@timestamp" => 2017-02-27T20:35:00.726Z,
"@version" => "1",
"host" => "REDACTED.local",
"message" => [
[0] 172,
[1] 19,
[2] 73,
[3] 1
]
}
```
