Java生產環境下性能監控與調優詳解

download：Java生產環境下性能監控與調優詳解

本課程將爲你講解如何在生產環境下對Java應用作性能監控與調優；經過本課程，你將掌握多種性能監控工具應用，學會定位並解決諸如內存溢出、cpu負載飆高等問題；學會線上代碼調試，Tomcat、Nginx，GC調優等手段； 讀懂JVM字節碼指令，分析源碼背後原理，提高應對線上突發情況的能力

適合人羣
具有至少一個項目開發和上線經驗的同窗
想學習生產環境下應用監控與調優技術的同窗
想提升解決生產環境的各類性能問題的能力的同窗
正準備晉級Java中高級工程師的同窗

技術儲備要求
有Java,Linux,Tomcat,Nginx等
Java初中級工程師必備技術基礎
