SNMP traps (performance alerts)

See Enable SEM to receive SNMP traps by turning on the SNMP Trap Logging Service in the online SEM Administrator Guide for details.

SEM accepts device input using the TCP and UDP protocols.

  • Network devices use TCP or UDP to send syslog events to the SEM Manager.

  • SEM Agents installed on servers and workstations use TCP to push data to the SEM Manager.

  • SolarWinds Orion/VMan server instances (including NPM and SAM) send SNMP traps over UDP to the SEM Manager.
