Thermostat is a monitoring and instrumentation tool for the OpenJDK HotSpot Java Virtual Machine (JVM) with support for monitoring multiple JVM instances. Thermostat supports monitoring and gathering performance data from JVMs running on the same machine, a remote machine, or across a network. The tool consists of three components: an agent, which collects data, a client, which allows users to visualize collected data, and a storage layer, over which the agent and the client communicate. A pluggable agent and GUI framework allow users to collect and visualize performance data beyond what is included out of the box.
The thermostat1 packages have been upgraded to upstream version 1.2.0, which provides a number of bug fixes and enhancements over the previous version. Among others:
A new instrumenting profiler plug-in has been added.
The setup of secured Thermostat using web storage has been simplified; the default setup has been changed to use HTTP-based storage.
Various improvements have been introduced, for example, in the Swing client GUI and in a number of charts.
The following security issue was fixed in the thermostat1-thermostat component:
It was discovered that the Thermostat web application stored database authentication credentials in a world-readable configuration file. A local user on a system running the Thermostat web application could use this flaw to access and modify monitored JVM data, or perform actions on connected JVMs. (CVE-2015-3201)
This issue was discovered by the Red Hat Thermostat Team.
Users of thermostat1 are advised to upgrade to these updated packages, which fix these issues and add these enhancements.
