Are you trying to create a field based on parsing of a log line or a syslog record? If so, you should create this field at index time using something like Logstash.

Hi @tbragin @magnusbaeck , Please can you see the below problem.Fileld is added into Kibana but it's not getting data form that message.Field is going to hidden into kibana fields section.
**Log:**
2015-04-17 23:35:46,932 [10] DEBUG Component.MessageHandler - ID already exists
**Pattern:**
- see the below configuration.
filter{
grok {
match =\> { "message" =\> "(?m)%{TIMESTAMP\_ISO8601:time} [%{NUMBER:thread}] %{LOGLEVEL:loglevel} - %{GREEDYDATA:msg} " }
}
mutate {
add\_field =\> {
"loglevel" =\> "%{LOGLEVEL:loglevel}"
}
}
}
