Java Flight Recorder - 缺少文件写入/读取事件
[英]Java Flight Recorder — missing File Write/Read events
问题描述
I am analyzing java8 JVM-process with Java Mission Control + Flight Recorder. 
我正在使用Java Mission Control + Flight Recorder分析java8 JVM-process。
When checking the recording under I/O tab, it says: 在I / O选项卡下检查录制时，它说：
"Event types 'File Write' 'File Read' are not enabled in this recording"
When creating the recording, in the recording wizard, last dialog Event Details... , as far as I can see, everything already has Enabled=True , but I cannot find any setting for File Write/Read ... 在创建录制时，在录制向导中，最后一个对话框事件详细信息... ，据我所见，一切都已启用Enabled = True ，但我找不到任何文件写入/读取设置 ...
How do I enable them? 我该如何启用它们？
