SNMP traps (performance alerts)

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

LEM accepts device input using the TCP and UDP protocols.

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

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

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