How to do "Pivot Faceting" like Solr-4.0 in elasticsearch-1.1.1 or later version?

次の記事のような集計をelasticsearchで実現するクエリが分からず困っております。

期待する結果は、SQLで言う所の次のクエリに相応するものです。

SELECT `都道府県`, `物件種別`, COUNT(*) FROM sample_data GROUP BY `都道府県`, `物件種別`;

How do you plan for using Filter for Fluentd v1?
<match apache.access>
type record_reformer
enable_ruby false
tag reform.apache.access
<record>
hostname ${hostname}
</record>
</match>
<match reform.apache.access>

I'd like to make a common name for each Fluentd role.

Name

  • Fluentd Cluster ... whole of fluentd system
  • Fluentd Node ... type of role
  • Fluentd Instance ... each fluentd process

Role

  1. Forwarder ... forwarding log to Aggregator node
  2. Aggregator ... Aggregate log from forwarder node

EPEL経由でNginxをインストールしたときに設置される404エラー時のHTMLです。 こちらは、Nginx公式リポジトリでは提供されていないファイルです。 設置場所は「/usr/share/nginx/html/404.html」でした。 使われ方は後述の sample.conf の通りです。
