Error Message Recording and Reporting in the SLC Control System
N. Spencer, J. R. Bogart, N. Phinney, Katherine A. Thompson · IEEE Transactions on Nuclear Science · 1985
Error or information messages that are signaled by control software either in the VAX host computer or the local microprocessor clusters are handled by a dedicated VAX process (PARANOIA). Messages are recorded on disk for further analysis and displayed at the appropriate console. Another VAX process (ERRLOG) can be used to sort, list and histogram various categories of messages. The functions performed by these processes and the algorithms used are discussed.
