We introduce the control system of the SuperKEKB collider which is based on EPICS. We standardize the CPU module so that we easily maintain our huge control system. Most Input/Output Controllers (IOCs) installed along the 3 km beamline at SuperKEKB are developed with only two kinds of CPU module. In addition to providing standard IOC for individual hardware, we develop some beam operation system which promotes the beam commissioning. The alarm monitoring system, abort trigger system, and Beam Gate system are developed by the control group. The sophisticated Beam Gate system for positron beam controls operation of both damping ring and main ring. It obviously promotes the beam commissioning at those rings. The other highlight is the precisely synchronized control system. It is necessary to realize the highly complicated control of beam injection process. We configure the dedicated network with the Event Timing System and the distributed shared memory. The distant hardware components are synchronously operated with this network. The beam commissioning of SuperKEKB has been started in 2016. The control system supports its fruitful beam operation without serious problem.

The monitoring system has been deployed to efficiently monitor IT infrastructure and EPICS control system at SuperKEKB. The system monitors two types of data: metrics and logs. Metrics such as network traffic and CPU usage are monitored with Zabbix. In addition, we developed an EPICS Channel Access client application that sends PV values to Zabbix server and the status of each IOC is monitored with it. The archived data in Zabbix are visualized on Grafana, which allows us to easily create dashboards and analyze the data. Logs such as text data are monitored with the Elastic Stack, which lets us collect, search, analyze and visualize logs. We apply it to monitor broadcast packets in the control network and the frequency of Channel Access search for each PV. Moreover, a Grafana plugin is developed to visualize the data from pvAccess RPC servers and various data such as CSS alarm status data can be displayed on it.
