Integrating SNMP with EPICS for Enhanced Network Management and Monitoring
Discover how SNMP (Simple Network Management Protocol) can be utilized in the EPICS control system to associate network traffic with control system anomalies. This integration allows for the retrieval of statistical data from SNMP-enabled devices such as switches and routers, enhancing monitoring capabilities. Explore supported EPICS record types including Longin, Analogin, and Stringin, and understand various SNMP data types. Consider potential enhancements for output support and alarm management, leveraging existing SNMP utilities to improve overall system performance.

devSnmp- device support for SNMP Richard Dabney,LANL rdabney@lanl.gov
devSnmp • SNMP – Simple Network Management Protocol • Telecom industry standard • Supported in all enterprise-targeted (LAN) network devices and in most service provider-targeted (WAN) devices.
devSnmp • What is it used for in EPICS? • Co-relate control system aberrations with network traffic. • How? • Retrieve statistical information from network switches and routers.
devSnmp • Features • Queries SNMP-enabled devices • Communications equipment i.e. switches, routers • Anything that supports SNMP • Input only, no output (yet) • Uses net-snmp APIs
devSnmp • EPICS record types supported • Longin • Analogin • Stringin
devSnmp • SNMP data types • Counter • Signed integer • IPAddress,NetworkAddress • OID • String • Gauge (records peak) • TimeTicks
devSnmp • Counters,Gauges are at least 32-bit unsigned (SNMPv1). Some are 64-bit unsigned (SNMPv2) • EPICS longin is 32-bit signed. use EPICS analogin. • EPICS strings are 40 chars max
devSnmp • Other possible uses • IOC management? • Workstation/server management? • ???
devSnmp • To do/enhancements • Output support? • Trap/Alarm support?
devSnmp • Alternatives • Use other available SNMP utilities to log SNMP data. • Use the new archiver???. • ???
