Access Log Filter

Elastic Stack Logstash

I am using following filter but this is not fetching response code and timetaken as column in elastic search. Any suggestions?

{ "message" => [ "%{TIMESTAMP_ISO8601:log_timestamp} %{NOTSPACE:s-sitename} %{NOTSPACE:s-computername} %{IPORHOST:s-ip} %{WORD:cs-method} %{URIPATH:cs-uri-stem} %{NOTSPACE:cs-uri-query} %{NUMBER:s-port} %{NOTSPACE:cs-username} %{IPORHOST:c-ip} %{NOTSPACE:cs(User-Agent)} %{NUMBER:sc-status:int} %{NUMBER:sc-substatus:int} %{NUMBER:sc-win32-status:int} %{NUMBER:sc-bytes:int} %{NUMBER:cs-bytes:int} %{NUMBER:time-taken:int}","%{TIMESTAMP_ISO8601:log_timestamp} %{NOTSPACE:s-sitename} %{NOTSPACE:s-computername} %{IPORHOST:s-ip} %{WORD:cs-method} %{URIPATH:cs-uri-stem} %{NOTSPACE:cs-uri-query} %{NUMBER:s-port} %{NOTSPACE:cs-username} %{IPORHOST:c-ip} %{NOTSPACE:cs(User-Agent)} %{NUMBER:response:int} %{NUMBER:sc-substatus:int} %{NUMBER:time-taken:int}","%{TIMESTAMP_ISO8601:log_timestamp} %{WORD:cs-method} %{URIPATH:cs-uri-stem} %{NOTSPACE:cs-uri-query} %{NUMBER:s-port} %{IPORHOST:c-ip} %{NOTSPACE:cs(User-Agent)} %{NUMBER:sc-status:int} %{NUMBER:sc-substatus:int} %{NUMBER:sc-win32-status:int} %{NUMBER:sc-bytes:int} %{NUMBER:cs-bytes:int} %{NUMBER:time-taken:int}" ] }
