Recipe Json To Elasticsearch

Looking to get data out of json into elasticsearch? You can do that with fluentd in 10 minutes!
Here is how:
$ gem install fluentd
$ gem install fluent-plugin-elasticsearch
$ 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 elasticsearch
  logstash_format true
  host <hostname> #(optional; default="localhost")
  port <port> #(optional; default=9200)
  index_name <index name> #(optional; default=fluentd)
  type_name <type name> #(optional; default=fluentd)
</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..
