I highly recommend this book to any role involved with developing .NET software.

Opsview is enterprise network and application monitoring software designed for scalability, flexibility and ease of use. Opsview has been in development since 2003 and is released under the GNU GPL license. Current version is 2.12. Opsview is a fully integrated monitoring tool that incorporates popular Open Source software including Nagios, Net-SNMP and RRDtool. The Catalyst web framework provides an extensible monitoring and configuration user interface. Opsview software is supported on Linux (Debian, CentOS, RHEL and Ubuntu) and Solaris 10. It will monitor all common operating systems including Windows. Opsview extends the capabilities of Nagios in the following ways: * Distributed monitoring with high availability and fail-over * Much improved SNMP support with trap processing with rules engine * API supporting automation of Opsview configuration * Data warehouse for storage of historical performance and event data * Opsview Reports customisable reporting * Powerful configuration and management UI * Extended monitoring UI * Extensible architecture based on Catalyst Web Framework and Altinity middleware software

Virtualization offers advantages that include server consolidation, isolation, rapid provisioning, and improved change management processes. Since virtualization breaks the hardware dependency and isolates virtual machines from details about the physical servers on which they are hosted, virtual images can be moved from one hosting platform to another. They can also be cloned to create more virtual machines, as desired. One of the challenges with cloning virtual images is handling operating system, network, and application specific customization. This article provides a sample framework for automating virtual image activation on new host platforms. This article, along with a previous article on Using virtual image templates to deploy WebSphere Application Server, demonstrates an automated approach for quickly and easily provisioning new WebSphere Application Server environments. The sample deployment and activation code included with this article is independent of WebSphere Application Server and can be used in conjunction with other software inside a virtual image. The specific example provided here is for WebSphere Application Server V6 in VMware or XEN virtual images, using SUSE V10 as the guest operating system. The activation techniques described in this article can be used in conjunction with IBM Tivoli® Provisioning Manager as described in Using Tivoli Provisioning Manager to deploy composite virtual appliances.
