The Java Platform Debugger Architecture (JPDA) includes tools that also make inspecting and manipulating a running VM possible. The high level Java Debug Interface (JDI) is the main way to integrate a debugger into the VM. It communicates with a remote VM using the Java Debug Wire Protocol (JDWP).

Dynamic method tracing in in Java. Brian Duff ... If you want to change the places where you log dynamically, you're going to have to redeploy your app. Also, if the calls you want to log are not in code owned by you (e.g. in an upstream library, or the JDK itself), this approach may be difficult and require you to build a third party library ...
US20100125834A1 - Dynamic Tracing on Java …
https://patents.google.com/patent/US20100125834A1/en
Embodiments of the invention provide a method and system for tracing Java bytecode. The system provides a user interface for selecting the methods, both primary and secondary, that the user desires to monitor. The user can record the execution of the program and playback the execution of the program while monitoring each of the designated methods and the variables …
Native JDBC Dynamic Tracing - IBM

On the application server command line or other Java application command line, use the jdbc.db2.trace.monitor=true property to enable dynamic tracing. This example also directs the output to a file in the /tmp directory. The %j variable holds the fully qualified job name.-Djdbc.db2.trace.monitor=true-Djdbc.db2.trace.config=file:///tmp/jdbctrace.%j.txt
Dynamic Toolbox Tracing - IBM
https://www.ibm.com/support/pages/dynamic-toolbox-tracing
Sometimes tracing needs to be dynamically started and stopped without requiring the JVM be restarted. IBM Toolbox for Java now has the ability to start a monitor thread that listens on a TCP socket for changes to the current trace settings. This behavior is controlled with two JVM properties: 1. com.ibm.as400.access.Trace.monitor

https://github.com/d-akara/java-tracing-agent
Java Tracing Agent uses the Java Instrumentation support included in the JVM to modify existing bytecode of classes. As classes are loaded, they are modified prior to execution. Classes can also be modified at runtime if we change the tracing configuration. Features. Runtime updates Changes can be made while the application is up and running

Java: Trace execution of a dynamically loaded class. Bookmark this question. Show activity on this post. basically what i'm trying to do is to load dynamically a class with annotated methods, run the main method of the class then trigger some code when the annotated methods are called. public myclass { public static void myMethod1 () { mymethod2 (); } @trace …
Brief introduction to BTrace – a very useful dynamic ...
https://blogs.sap.com/2019/11/15/brief-introduction-to-btrace-a-very-useful-dynamic-tracing-tool/
Actually, in this scenario, we can use BTrace, a very useful and powerful tool to do dynamic tracing for on-line java program. BTrace can get much more detail information inner the program based on trace script without original program stop and restart, etc. but just run the trace script independently. Configuration . Download and config runtime
Implementing Distributed Tracing in a Java application ...

That’s where SigNoz comes into the picture. SigNoz is a full-stack open-source APM tool that provides metrics monitoring and distributed tracing. We will demonstrate implementing distributed tracing in a Java application in two sections: Running a sample Java application with OpenTelemetry. Visualizing traces data with SigNoz dashboards.

To print the name of the read or write system call and its arguments, use the printf statement: printf ("%s (%d, 0x%x, %4d)", probefunc, arg0, arg1, arg2); to trace the name of the current probe function and the first three integer arguments to the system call, available in the DTrace variables arg0, arg1, and arg2.
