Centralized Logging to a database with alerts and powerful RCP-UI
LEMA is an easy to use Log-Server. It supports asynchronous logging of multiple applications (log4j-appender). The logs are processed and save to a database. An RCP-UI supports Live View, History View with advanced filters. You can use it for Error Monitoring / Notification; in order to do this a rule-based labellng (for instance stacktrace grouping) is performed by the server.
These are examples of JavaFX taken from a tutorial
by Alla Redko and modified to run on a Raspberry PI
running Java 8.

The Energy Sensing and Monitoring Infrastructure of the GAMES project
This is part of the GAMES Project, which consists of a set of innovative methodologies and Open Source ICT tools for designing and managing energy efficiency in IT Service Centres. The ESMI is the monitoring and sensing infrastructure which allows the fine-grained measurement and provides both an event-based and a real-time stream of data conveying information about the energy consumption in the key points of the overall system. It is completed by a set of Nagios plugin and an assessment...
HOOPLE is a portable collection of C++ source code, featuring thread-safe objects for collections and event processing, RPC-style plugin-based encrypted networking (CROMP / octopus), bookmark collection management utilities, and a lot of other cool stuff.
This is the project page for HOOPLE version 1, which was retired on September 25 2010. The code supposedly still builds on both Linux (with gnu gcc) and on Windows (with ms visual studio).
Most of the code from hoople1 has moved into...
