Monitor SNMP traps

This topic applies to the following products if you are NOT using the Orion Log Viewer to monitor SNMP traps.

IPAM — NAM — NCM — NPM — NTA — SAM — SRM — VNQM

If you monitor a large number of devices, where each device may have many connected objects of its own, requesting information from each device is impractical. You can set up the SNMP Trap Server, and each managed device can notify it about any issues by sending a trap message.

SNMP traps are received by the SolarWinds Log Manager for Orion Trap Service, which listens for incoming trap messages on UDP port 162, and then decodes, displays, and stores the messages in the Log Analyzer database.

A SolarWinds installation can process approximately 1000 events (syslogs, traps, Windows Events, log files, or VMWare events) per second. See Log Analyzer Scalability in the Scalability Engine Guidelines. You can process more by increasing your hardware requirements over the minimum requirements.

View SNMP traps

To view SNMP traps in the SolarWinds Platform Web Console, click Alerts & Activity > Traps.

Monitored traps will open in the Log Viewer.

See View logs and events with the Log Viewer.

Before you begin

  • Configure devices to send SNMP traps to the IP address assigned to the SolarWinds Platform server. For more information about proper configuration, refer to the documentation supplied by the vendor of your devices.
  • Make sure the UDP port 162 is open for IPv4 and IPv6.
  • When you use SNMPv3 for polling a device and receive traps from it, confirm that the same authentication type (auth, noauth, or priv) is configured for both polling and traps.
