The RHQ project[1] is happy to release version 4.2 of our open source server monitoring and management framework.
RHQ provides the ability to monitor and manage PostgreSQL servers and has been showcased at PGDay.EU in Stuttgart last december.

RHQ 4.2 has been released on October 31, 2011. The focus of the release were improvements and fixes to the GWT UI and the
new drift detection feature, where you can directories monitored for configuration changes and can get alerts on such changes.

Other notable changes (to 4.1) include:
• support for Postgres 9.1 as a backend database
* initial support for a REST api to extract data from the server from clients that are not written in Java, but e.g. perl, python or even shell
* improved syncing of rhq-server configurations to more easily replicate server setup
* Korean installer messages by Ted Won
* Improved Twitter plugin and Twitter alert sender by Rafael Torres

RHQ is written in Java and provides a general framework for monitoring, alerting, central tracking of configuration, executing operations on managed resources, and performing other management tasks. RHQ is designed in a way that allows administrators to adapt RHQ to their specific IT environment by adding plug-ins or content that can be used to manage resources. Some of these features include:    
	• The actual functionality to talk to managed resources is provided by plug-ins and can thus be extended to whatever resources or frameworks are out there. RHQ provides a series of default resource plug-ins that covers a variety of common resources, including Windows, Linux, JBossAS, Apache httpd and Tomcat, MySQL, and Postgres.
	• Sending alert notifications is governed by plug-ins, so that it is easy, for example, to integrate RHQ with company-wide ticketing systems. Alert sender plug-ins for email and for logfiles are provided by default, as well as a sender that can run arbitrary scripts in the RHQ command-line language.
	• RHQ also offers the possibility to roll out software ("bundles") to groups of managed servers.
	• To store metric data, configurations, bundles, and other data, RHQ uses either Oracle or Postgres as its backend database.Administrators can access RHQ via a GWT-based UI or a command-line client.
