====== fluentd + elasticsearch + Kibana3 によるログ収集・可視化 ======

温度計などのセンサデータを、MA-E3xx により収集し、[[http://www.fluentd.org/|fluentd]] により
[[http://www.elasticsearch.org/|elasticsearch]] に集約し、\\
[[http://www.elasticsearch.org/overview/kibana/|Kibana3]] により可視化を行ってみます。\\
今流行りの BuzzWord, "IoT" っていう感じでしょうか。

構成イメージはこのようになります。

シリアルポートのデータを、TCP 変換してサーバに接続するというのは簡単だとは思いますが、\\
3G 回線が切れたときなど、通信ができないときのデータ欠損が避けらず、オススメできません。\\
シリアルポート通信はリモート側で終端し、この仕組みでデータを送信するのが今時の仕組みではないでしょうか。

===== 準備 =====

MA-E3xx 側には、fluentd をインストールする必要があります。
残念ながら、Ubuntu14.04 用の公式パッケージは用意されておりません。\\
パッケージでインストールしておかないと後々管理ができなくなりますので、
Mario FetkaさんのPPA [[https://launchpad.net/~mario-fetka/+archive/fluentd]] \\
からパッケージを作成し、インストールすることにします。

{{:mae3xx_tips:setup_fluentd:ppa_image.png|https://launchpad.net/~mario-fetka/+archive/fluentd}}

\\

パッケージ作成にあたっては、下記環境が前提となります。
  * 開発環境一式 (build-essential) をインストール済みであること。((参照: [[mae3xx_devel:build_essential_setup:start]]))
  * パッケージ作成用のパッケージ(devscripts)をインストール済みであること。((参照: [[mae3xx_tips:setup_softether:start]]))
  * Ruby 開発環境 (ruby-dev) をインストール済みであること。

※ fluentd を組み込んだファームウェアを、"[[download_software:mae3xx:mae3xx_fluentd:start]]" に置いてあります。

\\

==== Ruby 開発環境のセットアップ ====

Ruby2.0 を使用したい(([[mae3xx_tips:test_fib_benchmark:start]] の結果の通り、Ruby1.9系より高速なためです。))ので、ruby2.0, ruby2.0-dev をインストールします。

上のとおり、ruby1.9.1 も一緒にインストールされてしまいます。

user1@plum:~$ ruby -v

\\

単に "ruby" として実行すると、Ruby1.9 系がデフォルトとなっているため、Ruby2.0 系をデフォルトにする設定をします。\\
参考: [[http://mhag.hatenablog.com/entry/2014/07/04/151415|´・ω・)＜ときどき書くよ - Ubuntu 14.04 LTS に Fluentd をインストールする]]

===== パッケージの作成 =====

==== PPA の追加 ====

PPA を追加します。

<code>

</code>

\\

バイナリパッケージが準備されていないものがありますので、PPA のソースパッケージの項を有効にします。

<code>
user1@plum:~$ sudo nano -w /etc/apt/sources.list.d/mario-fetka-fluentd-trusty.list
</code>

<code>

</code>

"deb-src" の前のコメントを外して保存します。

\\

追加された PPA のパッケージ情報を取得するため、apt-get update によりパッケージ情報を更新します。

<code>

==== パッケージのビルド ====

Fluentd 本体は "ruby-fluentd" ですが、下記パッケージに依存しています。
  * ruby-iobuffer
  * ruby-cool.io

両方共 ARM 用バイナリパッケージが準備されていませんので、ソースパッケージをダウンロードしてビルドを行います。

セットアップ後、自動で起動処理が行われてしまいました。\\
設定ファイル /etc/fluent/fluent.conf が無いので起動は失敗したようです。

\\

==== 動作テスト ====

簡単な設定ファイルを作り、基本的な動作確認をしてみます。

<code>
user1@plum:~$ sudo mkdir /etc/fluent
user1@plum:~$ sudo nano -w /etc/fluent/fluent.conf 
</code>

<file conf fluent.conf>
<source>
  type forward
</source>
<match debug.*>
  type file
  path /tmp/fluent_debug.txt
</match>
</file>

標準入力から入ってきたものの中で、タグが "debug.*" にマッチしたものを /tmp/fluent_debug.txt へ出力する設定です。

\\

fluentd を起動します。

<code>
user1@plum:~$ sudo service ruby-fluentd start
 * Starting fluent  fluent                                                                             [ OK ] 
user1@plum:~$ 
</code>

\\

単純なデータを入力してみます。タグは "debug.test" にします。

<code>
user1@plum:~$ echo '{"key" : "value"}' | fluent-cat debug.test
</code>

\\

出力されたか確認してみます。

<code>
user1@plum:~$ ls -l /tmp/fluent_debug*                               
-rw-r--r-- 1 fluent fluent 109 Jul 25 15:09 /tmp/fluent_debug.txt.20140725.b4fefe4bdbaa9b437
user1@plum:~$ cat /tmp/fluent_debug.txt.20140725.b4fefe4bdbaa9b437 
2014-07-25T15:09:41+09:00	debug.test	{"key":"value"}
</code>

処理が行われたのが確認できました。

\\

===== サーバの設定 =====

==== コンテナの作成 ====

クライアント(MA-E3xx)側の Fluentd はとりあえずセットアップできましたので、データを蓄積・可視化するサーバ側もセットアップします。\\
今回は、サーバには LXC((docker による方法も、のちほど試そうと考えています)) によるコンテナ型仮想環境を準備します。\\

Fluentd の公式パッケージがサポートしているのが Ubuntu 12.04LTS (Precise) なので、Ubuntu 12.04LTS の環境を作成します。\\
参照: [[http://docs.fluentd.org/articles/install-by-deb]]

==== コンテナの起動 / 設定 ====

作成したコンテナを起動します。\\
まだネットワークの設定を行っていませんので、フォアグランドで起動させます。

<code>
user1@ubuntu:~$ sudo lxc-start -n precise64
</code>

<code>

ログインできました。

\\

使用する環境に合わせて、
  * ネットワーク設定
  * ユーザアカウント追加
などを行っておきます。ubuntu ユーザも削除しておくほうがよいと思います。
