OpenSolarisのDTrace Communityでは、DTraceスクリプトをまとめたものを、DTrace Toolkitとして公開しています。
(先日、DTrace Toolkitのバージョンがあがり、スクリプトが増えました。)
今回は、DTrace Toolkitの紹介をしてみたいと思います。
DTrace Toolkit
DTrace Toolkitは、サン・マイクロシステムズが作成した、DTraceのスクリプトを、機能別に分類してまとめたものです。
（なかにはまだ分類されていないスクリプトもいくつかあります。）
配布形態はフリーウェアとなっており、最新のバージョン0.82では、82個のスクリプトが入っています。
また、スクリプト以外にも、ドキュメントやスクリプトを作成する際のテンプレート等も入っています。

また、ご自分でスクリプトを作成する際には、DTrace Toolkitに入っているテンプレートを使ってみてください。
