Resolution

Syslog-NG is the supported syslog format for Security Event Manager. Syslog-NG is the default log forwarding utility for most firewalls, routers, and switches. See RFC 5424: The Syslog Protocol for more information about the Syslog-NG protocol.

Security Event Manager also accepts syslog data from devices running the Rysylog log forwarding utility. Data logged by Rsyslog-enabled devices must be included in a file with a specific data format so Security Event Manager can read the syslog data. See Will SEM accept Rsyslog and Syslog-ng log data? for more information.

Older syslog formats sent to Security Event Manager are not supported. See RFC 3164: The BSD syslog Protocol for more information.
