In Oracle HMP 2.2.8, SNMP traps, syslog errors and warnings will not be generated by the hardware agent (hwmgmtd). This issue applies to all supported Linux versions.
Use ipmievd utility to log IPMI SEL events from ILOM to syslog.
ipmievd is a binary that is part of the ipmitool package in HMP. See the man page for more information.
Use itpconfig (ILOM Trap Proxy) to forward the SNMP traps directly from ILOM.
See the Oracle Server Management Agents User's Guide for more information about itpconfig.
