OpenMUC is a software framework based on Java and OSGi that simplifies the development of customized monitoring, logging and control systems. It can be used as a basis to flexibly implement anything from simple data loggers to complex SCADA systems. The main goal of OpenMUC is to shield the application developer of monitoring and control applications from the details of the communication protocol and data logging technologies. Third parties are encouraged to create their own customized systems based on OpenMUC. OpenMUC is licensed under the GPL. We sell individual licenses on request.
