我正在尝试将 Virgo Web 服务器从 EclipseRT 连接到 Visual vm 以进行内存分析。
内存分析不可用（不可用。无法读取目标应用程序中的对象。请检查日志文件了解详细信息（使用帮助 | 关于 | 日志文件）。）
当我在日志中检查 Vsual vm 时，Visual vm 日志中的错误为：
“com.sun.tools.attach.AttachNotSupportedException：无法打开套接字文件：目标进程未响应或未加载 HotSpot VM”
Both uses same JVM Open jdk
Visual VM Overview
ID: 15414
Host: localhost
Main class: org.netbeans.Main
Arguments: --userdir /root/.visualvm/1.3.2 --branding visualvm
JVM: OpenJDK 64-Bit Server VM (23.7-b01, mixed mode)
Java: version 1.7.0_15, vendor Oracle Corporation
Java Home: /usr/lib/jvm/java-7-openjdk-amd64/jre
JVM Flags: <none>
Virgo Web server Overview
PID: 1483
Host: localhost
Main class: org.eclipse.equinox.launcher.Main
Arguments: -noExit
JVM: OpenJDK 64-Bit Server VM (23.7-b01, mixed mode)
Java: version 1.7.0_15, vendor Oracle Corporation
Java Home: /usr/lib/jvm/java-7-openjdk-amd64/jre
JVM Flags: <none>
当我用谷歌搜索时，发现两者都应该在同一个用户上运行。Visual vm 以“root”身份运行，Virgo 以“test”用户身份运行。
我尝试以测试用户身份启动 viusal，但出现以下错误：
test@ubuntuz620:/home/random$ jvisualvm --jdkhome /usr/lib/jvm/java-1.7.0-openjdk-amd64

在此先感谢普拉卡什
附有 Viusalvm 的完整日志消息
