Butterfly Web UI is a component based Java Web application framework. Like the rest of the Butterfly Components, Butterfly Web UI is extremely small and very flexible. Butterfly Web UI uses Butterfly Container internally, a state of the art dependency injection container. Using Butterfly Web UI, it is easy both to generate HTML for a Web browser or XML or JSON for a RIA frontend (Flex, JavaFX, Silverlight) or AJAX frontend. You also can easily create HTML layout templates that are reused throughout your Web application, so you don't have the layout hardcoded into every page. You can easily mix RIA and non-RIA Web application technology in the same Web application.
jniThreadCPUUsage is a Java library to get the amount of user and system CPU time used per thread. This is done via JNI, which calls getrusage() on the system. getrusage() is only available on Linux 2.6.26 or later and Solaris. One useful application of this is measuring the amount of CPU time used for a servlet request. getrusage() CPU time reporting is better than using the real time clock because it measures actual CPU time used and disregards times when the thread is idle or waiting (such as when it is waiting for network I/O).
CCI:U Open Course Labs is a Django-based Web application that interfaces cloud-computing infrastructure such as Amazon EC2 and NexR iCube Cloud. More backends may be added. It provides the access to cloud infrastructure in the form of "course labs" where course staff in an academy can manage the allocated computing resources and assignments easily. Course labs can also be used as course homepages.
allmon is a generic system for collecting and storing various runtime metrics collections used for system performance, health, quality, and availability monitoring purposes. The system also provides a set of data-mining algorithms useful for further performance analysis. Allmon is designed to harvest different metrics values coming from many areas of monitoring infrastructure. The collected data are based on quantitative and qualitative performance and availability analysis. Allmon collaborates with other analytical tools for OLAP multidimensional analysis and data mining processing. The tool can be used for production as well as for development (profiling) and QA (load testing) purposes.
