iDRAC7 provides Lifecycle log that contains events related to system, storage devices, network devices, firmware updates, configuration changes, license messages, and so on. However, the system events are also available as a separate log called System Event Log (SEL). The lifecycle log is accessible through iDRAC7 Web interface, RACADM, and WS-MAN interface.
When the size of the lifecycle log reaches 800 KB, the logs are compressed and archived. You can only view the non-archived log entries, and apply filters and comments to non-archived logs. To view the archived logs, you must export the entire lifecycle log to a location on your system.
