Monitor SNMP traps
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 SolarWinds Platform 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 162is 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.
