Syslog messages are received by the SolarWinds Syslog Service, which listens for incoming messages on UDP port
514. Received messages are decoded and stored in the SolarWinds Orion database. The SolarWinds Syslog Service can handle large numbers of simultaneously incoming Syslog messages from all your monitored devices.
A SolarWinds installation can process approximately 1 million Syslog messages per hour, which is about 300 Syslog messages per second. You can process more by increasing your hardware requirements over the minimum requirements.
You can view Syslog messages in the Orion Web Console or in the Syslog Viewer application.
UDP port 514is open for IPv4 and IPv6.
SolarWinds recommends setting up Enable RFC Relay in the service to
true to allow the service to restructure the message by adding the default facility, severity, or date.
