Need a GeoIP Example

Can someone provide a geoip example for logstash with a log file?

filter {
  if [fileset][module] == "apache2" or [event][module] == "apache2" {
    if [fileset][name] == "access" {
           grok {
              match => {
                 "message" => [
                    "%{IPORHOST:[apache2][access][remote_ip]} - %{DATA:[apache2][access][user_name]} \[%{HTTPDATE:[apache2][access][time]}\] \"(?:%{WORD:apache2.access.method} %{DATA:apache2.access.url} HTTP/%{NUMBER:apache2.access.http_version}|-)?\" %{NUMBER:apache2.access.response_code} (?:%{NUMBER:apache2.access.body_sent.bytes}|-)( \"%{DATA:[apache2][access][referrer]}\")?( \"%{DATA:[apache2][access][agent]}\")?",
                    "%{IPORHOST:[apache2][access][remote_ip]} - %{DATA:[apache2][access][user_name]} \[%{HTTPDATE:[apache2][access][time]}\] \"-\" %{NUMBER:[apache2][access][response_code]} -",
                    "\[%{HTTPDATE:[apache2][access][time]}\] %{IPORHOST:[apache2][access][remote_ip]} %{DATA:[apache2][access][ssl][protocol]} %{DATA:[apache2][access][ssl][cipher]} \"%{WORD:[http][request][method]} %{DATA:[apache2][access][url]} HTTP/%{NUMBER:[apache2][access][http_version]}\" %{NUMBER:[apache2][access][body_sent][bytes]}"
                 ]
              }
           }

           mutate {
              rename => {
                 "@timestamp" => "read_timestamp"
              }
           }
           date {
              match => [
                 "[apache2][access][time]",
                 "dd/MMM/yyyy:H:m:s Z"
              ]
              target => "@timestamp"
           }


           mutate {
              rename => {
                 "[apache2][access][agent]" => "[apache2][access][user_agent][original]"
              }
           }
           geoip {
              source => "[apache2][access][remote_ip]"
              target => "[apache2][access][geoip]"
           }

           if ![@timestamp] {
              mutate {
                 rename => { "read_timestamp" => "@timestamp" }
                 id => "fix @timestamp when missing"
              }
           }

        }

And of course you will need a mapping template.
