Summary
Improved monitoring and serviceability tool for Java applications

Current status
- Targeted release: Fedora 19

- Percentage of completion: 80%
Detailed Description
Thermostat is a serviceability and instrumentation tool for OpenJDK. The 1.0 release of thermostat brings a number of new features that developers may find very useful.
- More information for Hosts and Java Virtual Machines being monitored
- A stable API for external plugin developers
- Ability to use thermostat, securely, in a network or a cluster
- An experimental eclipse plugin that lets developers use eclipse as a thermostat GUI
The goal is to get the 1.0 release of thermostat into Fedora 19. If upstream also releases 1.1 before the alpha deadline for Fedora 19, we may use that instead.
Benefit to Fedora
Thermostat 1.0 makes Fedora a better platform for Java developers to run their software on, since it provides tools to examine their applications as they are running, whether it's on Fedora as a single developer's OS or Fedora as an OS on a cluster node.
Scope
Only the Thermostat packages will be affected by this change. The thermostat package(s) will be updated to the 1.0 release as soon as upstream releases it. All of thermostat's (current) dependencies are already in Fedora.
How To Test
Thermostat developers and packagers will test Thermostat using upstream test cases, as well as custom ones. Some Thermostat hackers will also organize a Fedora test day on Thermostat.
Others can test that thermostat works as expected by following these steps. No special hardware is required.
To install thermostat, # yum install thermostat
To test the command line interface of thermostat:
$ thermostat help $ thermostat help service $ thermostat shell
To test the graphical interface of thermostat in a single-machine case:
$ thermostat service & optionally run other Java programs, such as eclipse $ thermostat gui
A graphical application should show up showing the user's machine and all the Java processes running on it.
The examples shown in the User Guide should all work too.
User Experience
Thermostat 1.0 will not introduce major user interface changes. The command line will continue working mostly as before and the GUI client will look and behave mostly as before. A few new command line commands will appear and some new tabs will appear in the GUI client to display additional information.
Thermostat 1.0 will include a new and experimental eclipse plugin prototype that developers can use instead of the regular GUI client.
Dependencies
None. Thermostat is a stand-alone feature.
Contingency Plan
Prior to the 1.0 release, we will work with upstream to identify and fix major bugs and regressions on Fedora. If there are showstopper bugs, we will backport fixes or use the previous stable release.
If upstream delays the 1.0 release, we will use the latest stable release. This release may not have a stable plugin API.

Release Notes
- Fedora 19 includes Thermostat 1.0, the first API-stable release of thermostat, a monitoring, instrumentation and serviceability tool for OpenJDK.
