Java and native agents offer distinct capabilities for monitoring and updating JVM applications, with Harness SRM utilizing native agents to perform low-level, real-time error analysis without affecting performance. Java agents, typically .jar files, integrate with the JVM at runtime to modify class methods dynamically through bytecode instrumentation, enabling tasks such as profiling and hot-swapping classes. In contrast, native agents, often written in C++, leverage the JVM Tooling Interface (JVMTI) to access a broad range of JVM internals, allowing for powerful debugging and monitoring capabilities. While native agents provide greater access and control, they are more complex, require platform-specific compilation, and carry risks of JVM instability if improperly managed. Harness SRM primarily operates through native code, minimizing the footprint on server resources and ensuring compatibility with existing tools and agents.
