某所のフロントのWebサーバのアクセスログを、ちょっと調べてみたら、世界各国から色んなボットがアクセスに来ていることが確認できた。
こじんまりとしたサイトでも、本当にたくさんの種類のボットさんが"訪れて"くれています。
とりあえず、"/robots.txt"へのアクセスを元にカウント。きちんと調べればもっとたくさんはいそうだけど。
まぁ、"/robots.txt"に人がアクセスすることは、そんなにないだろうなー、と勝手に予想。
"Wget"とかも混じっているけど、これはお手製ボットなんだろうか、よくわからない。
とりあえず、UA(ユーザエージェント)だけを抽出してアクセスの多い順に出力してみた。ネタとして結果を貼り付けておきます。

全てがボットではないだろうけど、とりあえず↑のログは135種類ほど。
ちなみに、元のログファイルは、約140万リクエスト程度分のログです。
