I'm trying to convert responsetime from nginx access logs which is in seconds to milliseconds using ruby.

I was able to successfully GROK the access log.

grok {  
match =\> { "message" =\> "%{IPV4:clientip} - - [%{HTTPDATE:requesttimestamp}] "%{WORD:httpmethod} /" %{NUMBER:responsecode:int} %{NUMBER:responsesize:int} "-" "-" "-" "%{NUMBER:responsetimems:float}""}  
}  
ruby {  
code =\> "event.set('responsetimems', event.get('responsetimems').to\_i \* 1000))"  
}

Am i doing anything wrong here ?

That looks correct. What does an example event coming out of Logstash look like?
