剖析 Corda 应用程序
Profiling a Corda Application
我正在尝试 运行 针对 CorDapp 进行一些检测/分析 - 对于这个问题,示例 cordapp 在这里:https://github.com/corda/cordapp-example.git version release-3.
但是,当我尝试根据来自 corda shell 的 jvm runtime
将 VisualVM 附加到 运行ning PID 时,我收到如下错误:
(来自 VisualVM 的配置文件选项卡)
Mon Jun 11 15:17:36 BST 2018>>> Profiler Agent: JNI OnLoad Initializing...
Profiler Agent: JNI OnLoad Initialized successfully
Profiler Agent: Waiting for connection on port 5140 (Protocol version: 18)
Profiler Agent: Established connection with the tool
Profiler Agent: Local accelerated session
Profiler Agent Error: Exception when handling command from client:
java.io.InvalidClassException: filter status: REJECTED
Profiler Agent: Connection with agent closed
或(从采样器选项卡)
CPU sampling:
Not available. Cannot access threads in target application. Check the logfile for details (use Help | About | Logfile).
日志文件给我这个有用的错误:
WARNING [org.netbeans.modules.profiler.NetBeansProfiler]: IDEAppStatusHandler - error: {)}
*** Profiler error (Mon Jun 11 15:17:59 BST 2018): exception while trying to get response from the target JVM:
java.net.SocketException: Connection reset
INFO [com.sun.tools.visualvm.sampler.cpu.ThreadInfoProvider]: mxbeans.getThreadMXBean() returns null for Application [id: localhost-10884, pid: 10884, host: localhost]
我在 MacOS 和 Ubuntu 上都试过了,我遇到了同样的问题 - 所以我认为这不是 Java 安装问题。
有什么指点吗!?
VisualVM 使用 Java 序列化。出于安全原因,Corda 禁止 Java 序列化。
open protected fun banJavaSerialisation(conf: NodeConfiguration) {
SerialFilter.install(if (conf.notary?.bftSMaRt != null) ::bftSMaRtSerialFilter else ::defaultSerialFilter)
}
