java - 内存分析 - VisualVM 和 Virgo

Question

处理器:

64 bit OS Ubuntu server 64 bit

JAVA:

java version "1.7.0_15"
OpenJDK Runtime Environment (IcedTea7 2.3.7) (7u15-2.3.7-0ubuntu1~12.04.1)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

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。

Memory profiling is not available (Not available. Failed to read objects in target application. Check the logfile for details (use Help | About | Logfile).)

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: Unable to open socket file: target process not responding or HotSpot VM not loaded"

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用户上运行。 Visual vm 以“root”用户身份运行，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
/usr/share/netbeans/platform12/lib/nbexec: line 66: cd: /home/random: Permission denied
/usr/share/netbeans/platform12/lib/nbexec: line 66: cd: /home/random: Permission denied

提前感谢普拉卡什

附有 Viusalvm 的完整日志消息

Answer 1

您是否尝试过使用测试用户通过 ssh 连接服务器？
尝试一下

ssh test@yourmachine -X  

这是因为与一个用户进行 ssh-ing，然后使用另一用户的 sudo 运行 jvisualvm 可能会导致此问题...

顺便说一句，对我有用的是将 .Xauthority 文件按原样(注意这是一个二进制文件)从根主目录复制到特定用户的主目录(在您的情况下进行测试)。
