The Integrated Management Log (IML) is the primary log on HPE ProLiant servers for recording hardware-level events. It captures hundreds of events generated by the system ROM and various hardware components. The specific alerts mentioned—NIC link loss, temperature warnings, and automatic shutdowns due to critical events—are all classic examples of hardware and firmware-level incidents that are logged directly to the IML. Reviewing the IML is a fundamental step in diagnosing the health and status of the server hardware itself.

A. HPE OneView Activity Log: This log tracks activities within the OneView management appliance, such as user actions and aggregated alerts from multiple managed devices, not the primary hardware log of a single server.

B. Security Log: This is an operating system-level log that records security-related events like user logins, access attempts, and privilege changes, not hardware faults.

D. iLO Event Log: This log primarily records events related to the iLO management processor itself, such as user logins to iLO and remote management actions. While it may mirror some critical hardware events, the IML is the more comprehensive and authoritative source for server hardware events.

February 2020). On page 210

under the "Integrated Management Log" section

it states

"The IML records events that are generated by the system ROM and other system components." This confirms it as the source for system-level hardware events.

Volume I: Troubleshooting (Document ID: P19222-003

October 2020). In Chapter 3

"Troubleshooting tools

" the section "Integrated Management Log (IML)" (page 21) describes the IML as a key tool for diagnosing server issues

stating it "records events and can alert you to potential problems."

3. HPE Integrated Lights-Out (iLO 6) User Guide (Document ID: P49229-002

June 2023). On page 268

the "Integrated Management Log" section reiterates its function: "The IML provides a record of system events that can help you diagnose problems or potential problems with the server." It contrasts this with the iLO Event Log

which "records user and iLO activity" (page 267).
