主にISUCONで使われているアクセスログ集計ツール alp の使い方を、ISUCON10オンライン予選問題のアクセスログを例に紹介します。

https://github.com/tkuchiki/alp

執筆時現在の最新バージョンはv1.0.7です。

インストール方法

https://github.com/tkuchiki/alp/releases 上のバイナリをダウンロードして利用することができます。
また、以下の方法でインストールすることもできます。

macOS

$ brew install alp

asdf

$ asdf plugin-add alp https://github.com/asdf-community/asdf-alp.git
$ asdf install alp <バージョン>
$ asdf global alp <バージョン>

サポートしているログフォーマット

alpは以下のログフォーマットをサポートしています。

また、解析するログフォーマットを正規表現で記述する機能もあるため、テキストフォーマットであればどのようなフォーマットのログでも解析することができます。
他にも、ログファイルではありませんが pcap ファイルを読み込むこともできます。

設定

alpでアクセスログを集計する前に、集計できるログフォーマットに変更する必要があります。
ドキュメントにログフォーマットごとのApache, Nginx, H2Oの設定例を記載していますのでそちらを参照してください。

使い方

alpはltsv, json, regexp, pcapの4つのサブコマンドで構成されています。

$ alp --help
usage: alp [<flags>] <command> [<args> ...]

alp is the access log profiler for LTSV, JSON, Pcap, and others.

  -r, --reverse                 Sort results in reverse order
  -q, --query-string            Include the URI query string
      --qs-ignore-values        Ignore the value of the query string. Replace

      --decode-uri              Decode the URI
      --format=table            The output format (table, markdown, tsv and csv)
      --noheaders               Output no header line at all (only --format=tsv,

デフォルトでは、COUNTの昇順でソートし、URIはQuery Stringを省略した状態で集計、テーブル形式で出力します。

アクセスログの集計結果を眺めると、/api/estate/8654/api/estate/15302など、同じようなURIが多いことに気がつきます。これらは、同じhandlerで処理されるので一つのURIとして集計したほうが良いことが多いでしょう。そのようなケースで役立つのが-mです。

Query Stringのキーだけを見て、全てのキーが一致していたら値に関係なく同一URIとして集計したい場合があるかもしれません。そのようなときは、-qと一緒に--qs-ignore-valuesを使います。
