<meta itemprop="description" content="Using E2E local remote debugging The E2E remote debugging port of service containers is 5005. If the developer wants to use remote debugging, he needs to add remote debugging parameters to the start service command, and then expose the port 5005.
For example, this is the configuration of a container in the skywalking/test/e2e/e2e-test/docker/base-compose.yml. JAVA_OPTS is a preset variable for passing additional parameters in the AOP service startup command, so we only need to add the JAVA remote debugging parameters agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 to the configuration and exposes the port 5005.">

SkyWalking provides an easy way to maintain a clear view of your distributed systems, even across Clouds. It is a modern APM, specially designed for cloud native, container based distributed systems.
Why use SkyWalking? SkyWalking provides solutions for observing and monitoring distributed systems, in many different scenarios. First of all, like traditional approaches, SkyWalking provides auto instrument agents for services, such as Java, C#, Node.">

<meta itemprop="description" content="Thread dump merging mechanism The performance profile is an enhancement feature in the APM system. We are using the thread dump to estimate the method execution time, rather than adding many local spans. In this way, the resource cost would be much less than using distributed tracing to locate slow method. This feature is suitable in the production environment. This document introduces how thread dumps are merged into the final report as a stack tree(s).">

<meta itemprop="description" content="Compatible with other javaagent bytecode processing Problem When use skywalking agent, some other agent, such as Arthas, can’t work well https://github.com/apache/skywalking/pull/4858
Java agent retransforming class fails with Skywalking agent, such as in this demo
Reason SkyWalking agent uses ByteBuddy to transform classes when the Java application starts. ByteBuddy generates auxiliary classes with different random names every time.
When another java agent retransforms the same class, it triggers the SkyWalking agent to enhance the class again.">
