The Beam Instrumentation and Measurements group at the Facility for Rare Isotope Beams is responsible for maintaining several EPICS IOC instances for beam diagnostics, of different IOC types, which end up generating tens of thousands of PVs. Given the heterogeneity of Diagnostics devices, the need to archive data for scientific and debugging purposes, and space limitations for archived data storage, there is a need for having per-PV (as opposed to per-Record) archiving rules in order to maximize utility and minimize storage footprint. This work will present our solution to the problem: "IOC Manager", a custom tool that leverages continuous integration, a relational database, and a custom EPICS module to allow users to specify regular-expression based rules for the archiver in a web interface.

The Beam Instrumentation and Measurements department is responsible for dozens of different diagnostics devices deployed at multiple locations at the Facility for Rare Isotope Beam. In order to manage such a high number of devices, different tools were created to address preventive and corrective maintenance tasks and check the overall health of the equipment. This work will present how the EPICS tools and frameworks, such as archiver, channel finder, and pyDevSup, were integrated with our environment to help achieve a high availability for the beam diagnostic devices.
