Here is how:

$ gem install fluentd
$ gem install fluent-plugin-mongo
$ touch fluentd.conf

fluentd.conf should look like this (just copy and paste this into fluentd.conf):

<source>
  type tail
  path /var/log/httpd-access.log #...or where you placed your Apache access log
  pos_file /var/log/td-agent/httpd-access.log.pos # This is where you record file position
  tag foobar.json #fluentd tag!
  format json # one JSON per line
  time_key time_field # optional; default = time
</source>

<match **>
  type mongo
  database <db name> #(required)
  collection <collection name> #(optional; default="untagged")
  host <hostname> #(optional; default="localhost")
  port <port> #(optional; default=27017)
</match>

After that, you can start fluentd and everything should work:

$ fluentd -c fluentd.conf

Of course, this is just a quick example. If you are thinking of running fluentd in production, consider using td-agent, the enterprise version of Fluentd packaged and maintained by Treasure Data, Inc..
