System Event Log
The System Event Log stores platform events so that they are available for later analysis.
System event logging includes the logging of warning and critical events, extreme chassis
temperatures, and voltages.
Logged events are transported and maintained by the IPMI system. The BMC provides the
interface to the SEL for both the IPMB and the System Management Software (SMS) running
under the operating system.
System Management Software can retrieve events from the log and move them to non-volatile
storage, such as a hard disk, the alarm board or some form of removable storage. SMS also has
the ability to delete events from the system event log. This is a necessary maintenance function
due to the limited resources on the BMC.
