    Java Performance Monitoring Tools

    This month, we'll hear from Lukas Berk, a Red Hatter who works on Java tracing and profiling support within SystemTap[1]. SystemTap is a dynamic, scriptable kernel-space and user-space probing system for Linux. It can be used directly by end users (without requiring modifications to the source program), or as a back-end for higher level performance tools.

    Speaking of tools, Omair Majid, another Red Hatter, will treat us to a second talk. Omair works on Thermostat[2], a distributed, modular monitoring and profiling tool for Java. Thermostat gathers statistics from many sources. After a brief overview of Thermostat, Omair will unveil the brand new plugin API, which allows Java developers to introduce new input (telemetry sources) and output (reporting) capabilities to Thermostat. This is a brand new API that's still not frozen. Feedback on use cases and API design is both welcome and encouraged!
