As part of the larger vFabric 5.1 release this week, Hyperic delivered on an upgrade to managing Apache Tomcat, the world’s most popular application server. Starting with updating support for the latest version, Apache Tomcat 7, Hyperic upgraded support for Tomcat in three major ways.
Support for Apache Tomcat 7
Tomcat 7 is gaining adoption in the marketplace, including with enterprise users. To support this, the latest release for Hyperic adds support for Apache Tomcat 7, the latest stable release published by the Apache Software Foundation.
Improve Performance for Hyperic’s Internal Tomcat Server on Large Implementations
The Hyperic server configuration properties have been expanded to better manage the how many threads are available to the Hyperic Server’s internal Tomcatserver. Two new properties have been established
tomcat.minsparethreads, whose default values in Hyperic HQ are 500 and 50, respectively. Default values are set for deployments under fifty platforms. If your deployment is larger than that, guidance is outlined in the Hyperic documentation to help you tune your internal Hyperic server. See “Scaling and Tuning Hyperic Performance” in vFabric Hyperic Installation and Configuration for more about
tomcat.minsparethreads, and other server properties you can use to tune the Hyperic Server in large environments.
Detailed Configuration History Tracking For Tomcat
Hyperic 4.6.5 introduces new support for detailed configuration tracking. Previously, Hyperic would identify only be able to identify that a file had been changed. While it would identify the specific file, it was then up to administrators to investigate where the change occurred in the file manually. Now, Hyperic will identify the type of change including “add”, “delete”, “modify”, or “rename” to a file and also specify the actual changes in text files, saving administrators additional steps while troubleshooting problems. This functionality has been implemented initially in only a few of the most popular web infrastructure software, starting with Apache Tomcat and also including others such as Apache, WebSphere, WebLogicServer, JBoss, PostgreSQL, mySQL, and Oracle. For more information on how to use this new configuration tracking, Hyperic documentation, see “Log and Configuration Event Tracking” in vFabric Hyperic Overview for more about the configuration tracking functionality, and see “FileChangeTrackPlugin” in vFabric Hyperic Plug-inDevelopment for more about the new support class.
