What is Swiss Java Knife?
SJK (Swiss Java Knife) is a command-line tool and library for JVM diagnostics, troubleshooting, and profiling. It solves problems related to monitoring Java application performance, analyzing memory usage, and profiling thread activity by leveraging standard JVM interfaces like JMX and JVM attach. It provides a unified set of utilities to replace or enhance scattered diagnostic commands.
Java developers, DevOps engineers, and performance analysts who need to diagnose production JVM issues, profile application performance, or build custom monitoring tools.
Developers choose SJK for its comprehensive feature set that goes beyond basic JDK tools, its ability to work without enabling JMX servers, and its extensibility as a library for embedding diagnostics into applications.
