Abstract

We describe the design and implementation of xdProf: a tool that captures and analyzes stack traces sent at a fixed interval from Java Virtual Machines in a distributed system. The xdProf client uses the Java Virtual Machine Profiling Interface and works with any compliant implementation; no access to application source code is necessary, no library modifications are needed, and there is no run-time instrumentation of Java byte code. Configuration options given at virtual machine startup specify the interval for stack trace transmission and the remote xdProf server. The xdProf server collects information from multiple xdProf clients and provides an extensible interface for analysis. Current tools include a graphical user interface for viewing the most recent stack traces from multiple virtual machines and the generation of control flow graphs for each virtual machine. The performance impact of the xdProf client sending data over a local area network is minimal: less than a 8% increase in total elapsed time for a set of standard benchmarks. Future plans include real-time visualization, reliability estimation, trace capture, and performance analysis.
