Development of monitoring system for network switches and UPS units using EPICS

The constructions of J-PARC accelerators have been made, and operation of accelerators started already. Increase needs have been arisen to observe trends of (a) control traffic at network switches, and (b) power consumption rates at UPS units for computers and electronics. Though our control system is EPICS-based, we did not have any method to monitor them from the control system. Since both of network switches and UPS units are SNMP(Simple Network Management Protocol)-implemented devices, we introduced devSnmp, EPICS device support for SNMP devices. Then, EPICS databases and GUI applications were developed. This article gives detailed information of this monitoring system. (author)
