Connecting MonALISA and EPICS
Introduction
MonALISA
MonALISA stands for
Monitoring Agents using a Large Integrated Services Architecture, is based on Dynamic Distributed Service Architecture and is able to provide complete monitoring, control and global optimization services for complex systems.
The MonALISA system is designed as an ensemble of autonomous multi-threaded, self-describing agent-based subsystems which are registered as dynamic services, and are able to collaborate and cooperate in performing a wide range of information gathering and processing tasks. These agents can analyze and process the information, in a distributed way, to provide optimization decisions in large scale distributed applications. An agent-based architecture provides the ability to invest the system with increasing degrees of intelligence, to reduce complexity and make global systems manageable in real time. The scalability of the system derives from the use of multithreaded execution engine to host a variety of loosely coupled self-describing dynamic services or agents and the ability of each service to register itself and then to be discovered and used by any other services, or clients that require such information. The system is designed to easily integrate existing monitoring tools and procedures and to provide this information in a dynamic, customized, self describing way to any other services or clients.

The question to be tagged was to establish a basic communication link from MonALISA to be able to read/write EPICS variables.
Using the API of MonALISA and the pEZCA.pm Perl EPICS Interface we managed to perform this task.
The attached source comprises the whole directory tree built during establishing the communication IOC ⇔ MonALISA.
Source (due to limitations the file had to split via

into two parts, recombine using

):
What is missing is the source of the web-based GUI part.
