Cisco UCS Faults and Error Messages Reference Guide, Release 2.5, for Cisco UCS M-Series Servers
Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Introduction to System Event Log Messages
Introduction to System Event Log Messages
This chapter provides general information about System Event Log Messages. The following sections are included:
Information about System Event Log Messages
The system event log (SEL) resides on the CIMC in NVRAM. It records most server-related events, such as over- and under-voltage, temperature events, fan events, events from the BIOS, and so on. It also records platform errors such as memory errors, CPU errors, and so on.
The SEL is mainly used for troubleshooting purposes. UCSM uses SEL records to provide mechanisms for proactive health monitoring of the system (for example, faults and error statistics).
Tip
For more information about the SEL, including how to view the SEL for each server and configure the SEL policy, see the Cisco UCS configuration guides accessible through the Cisco UCS B-Series Servers Documentation Roadmap.
SEL File
The SEL file is approximately 40 KB in size, and no further events are recorded when it is full. It must be cleared before additional events can be recorded.
SEL Policy
The SEL policy can be configured to backup the SEL to a remote server, and, optionally to clear the SEL after a backup operation occurs. A back up operation can be triggered based upon the following actions defined by the user as a part of SEL backup policy.
