近期在設計一個DevOps平臺。希望整合一個APM工具進來，由於APM既可用於性能測試也可用於運維性能監控，是典型的Dev+Ops產品。

商業的APM工具國內外已經有不少成熟產品了，而開源的好像不多見。我想APM工具的原理是基於JVM動態註入，從技術角度考慮，必定會有開源的東西出現才對，所以開始了開源APM應用性能管理工具調研之旅！

今天找到一個叫Kieker 的：

Kieker provides complementary dynamic analysis capabilities, i.e., monitoring and analyzing a software system’s runtime behavior — enabling

Application Performance Monitoring and Architecture Discovery.

看起來Kieker還比較活躍，最新版本號是2015年1月1日公布的：

Kieker 1.12 (stable)

The current stable Kieker release is version 1.12 (released on October 1, 2015).

• Download the Kieker binary release 1.12 as zip or tar.gz
• Download the Kieker source release 1.12 as zip or tar.gz
• Download the Kieker user guide 1.12 as pdf

• Download the Kieker WebGUI binary release 1.12 as: zip or tar.gz
• Download the Kieker WebGUI source release 1.12 as: zip or tar.gz

另外找到一個叫Pinpoint的：

https://github.com/naver/pinpoint

Pinpoint

is an APM (Application Performance Management) tool for large-scale distributed systems written in Java. Modelled after Dapper, Pinpoint provides a solution to help analyze the overall structure of the system and how components within them are interconnected by tracing transactions across distributed applications.

• Install agents without changing a single line of code
• Minimal impact on performance (approximately 3% increase in resource usage)

眼下最新版本號：
2015/12/11公布的v1.5.1
