2. SEL Overview
The System Event Log (SEL) is a non-volatile repository for event messages. Event messages
contain information about system events and anomalies that occur on the server, BIOS, and
event generators. System sensors can also trigger events that are logged in the SEL.
Some event messages are the result of normal events, such as a normal server boot, or
possible minor problems such as a disconnected keyboard. Other events may indicate internal
failures such as a component over-temp condition where thresholds, or ranges of acceptable
values have been exceeded. As with other system events, if at any time a component crosses
one of these defined thresholds, an event message will be generated.
Regardless of the event, the appropriate management controller generates an event message.
Event messages are passed to the Baseboard Management Controller (BMC), the primary
management controller on Intel® server systems. The BMC passes the event message to the
SEL where it becomes available for querying by the SEL Viewer utility.
The SEL Viewer provides an interface for the server administrator to view information in the
SEL. The SEL Viewer is available through the Intel® Server Management (ISM) or the EFI
based SEL Viewer utility which is available in the System Management Utility (SMU) that ships
on the standard platform resource CD. The system administrator can use this information to
monitor the server for warnings and potential critical problems.
