chefのログ出力を制限する方法 / 劇的ビフォーアフター ver.0.10.6+ (verbose_logging)

chefのログが出すぎだなー、実際これ影響あるのかないのか
出力結果見るのにターミナルでスクロールバックしないといけないし
これだけの出力されたログの中で、影響があるのかないのか、ひとつひとつ
目grep警部してたら取りこぼし多そうだなー

やだなやだなー、こわいなこわいなー

と思ってたんですが

「optionally disable the verbose logging」という表記があるじゃないですか！！

リンク先を覗くと

The "processing" INFO message for every resource on a normal run looks nice but is probably too verbose. 
The messages are great if you're running chef-client in your terminal and want to know whats happening, 
but will fill up logfiles with unnecessary cruft. Also, using knife ssh will cause an explosion of ASCII proportions.

おお、そうなんだよ！！Processingはバーボスなんだよ！！
本当にほしいログってのはサーバに影響を及ぼしだログだけで
他のログはそんなに必要じゃないんだよおおおお！！！

わかるぜブラザー！！よっしゃ！
取り敢えずはコミット内容を見てみよう！！！

(　◔౪◔) ？

ちょっと意味がわからない。。って思ってたらなんと

Chef Configuration Settings

ドキュメントに載ってました。

verbose_logging set to true or nil

verbose_logging set to false

In Chef 0.10.6+, setting verbose_logging to false

これか！！ verbose_logging set to falseッッ！！

ど、どこに書いたらええんや！！！
どこなんやああああああああああああああああああああ！！！

と、血眼になって探したのですが
上記マニュアルの上の方に書いてありますね。

 chef-solo なら /etc/chef/solo.rb  
 chef-client なら /etc/chef/client.rb

ということで、うちは chef-solo を利用しているので
早速 /etc/chef/solo.rb に「verbose_logging false」を記入して実行してみましょう

影響があったものだけが出力されるようになる。

It's very simple!!

ということで、他のアップデート内容は確認していませんが
このログ出力制限のためだけでも chef を 0.10.6 にアップデートしても良いなと思いました。

Why-runも使えるし、0.10.6、なかなか良いですね。
