Keep newline formating with multiline

[pluto (John P)]

Here is my config file. I am processing java logs. The errors do come into Kibana but are all one long chunk of text. Is there a way to have the entry come in as one event but keep the formating so it is more readable?

input {
file {
path => [
"/home/glassfish/gf-logs/logs/server.log"
]
codec =>
multiline {
pattern => "^[\d{4}"
negate => "true"
what => "previous"
}
start_position => "beginning"
}
}

filter {
mutate {
remove_field => [ "@version" ]
remove_field => [ "path" ]
remove_field => [ "_score" ]
gsub => ["message", "\n", ""]
}
grok {
match => {
"message" => "[%{DATA:server_version}] [%{LOGLEVEL}] [] [%{JAVACLASS}] [%{DATA:thread}] [%{DATA}] [%{DATA}] [[%{DATA:logmessage} ]]"
}
}
date {
match => [
"timestamp", "ISO8601"
]
target => "@timestamp"
}
kv {
source => "logmessage"
}
}

output {
elasticsearch {
hosts => [ "192.168.15.242:9200" ]
index => "beta-%{+YYYY.MM.dd}"
}
}

I don't understand. What do your events currently look like? What would you like them to look like instead?

(Side note: For efficiency reasons you should never use more DATA or GREEDYDATA patterns than necessary. You don't need more than one in this case.)

Thanks for your help

I figured it out, this line was removing the newline and messing up the formatting.
gsub => ["message", "\n", ""]
