}  
filter {  
grok{  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|%{WORD:PROCESS}\s+%{NUMBER:DURATION:float}\s+%{WORD:UNIT}"}  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|[%{WORD:PROCESS}]\s+%{NUMBER:DURATION:float}\s+%{WORD:UNIT}"}  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|(?%{WORD} %{WORD} %{WORD})\s+:\s+%{NUMBER:DURATION:float}\s+%{WORD:UNIT}"}  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|[%{WORD:PROCESS}]"}  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|\<%{WORD:PROCESS}\>"}  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|\<%{WORD:PROCESS}\>\s+%{NUMBER:DURATION:float}\s+%{WORD:UNIT}"}  
match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:LOGTIME}|%{WORD:LOGLEVEL}|%{WORD:MACHINE}|%{WORD:PROCESSID}|%{WORD:SERVICENAME}|%{GREEDYDATA:MSG}"}

`LOGTIME` will stay as _string_ but @timestamp should now be equal to the date of `LOGTIME`.
