RHQ是一個可擴展的，支持多種產品和平臺的系統管理套件，它具有以下功能： 

* 圖形化監控
* 錯誤報警
* 遠程配置資源
* 遠程操作

RHQ的具體特性

Inventory   ：提供可管理資源的信息

Response Times：被請求資源的實時響應信息
Configuration：以便你查看修改配置信息
Operations：操作資源

RHQ采用的是Server/Agent的架構，這樣就是RHQ的擴展變得更加容易。

RHQ 4.4 發布了，該版本除了修復了很多 bug 之外，還包含大量改善，主要有如下內容：

• Availability now knows a type of "disabled". This allows you to mark resources while maintenance or non-connected network interfaces so that they do not show up as down and also don't create false alerts. This also includes the possibility that plugins request to mark a resource as enabled or disabled
• Faster availability reporting
• Faster availability checking in the agent, that is also less bursty than in the past
• Plugins can now request an availability check for a resource
• Alerting has been improved: It is now possible to react on availability being in a certain state for some period of time (see the release notes for a long explanation
• The JBoss AS 7 plugin has been massively improved
• Denis Krusko has provided some initial Russian translations of the UI
• Reports like Suspect Metrics, Recent Operations or Recent Drift can now be exported in CSV format to e.g. post-process them in Open/LibreOffice.
