A BIG-IP Administrator suspects that one of the BIG-IP device power supplies is experiencing power...

On a BIG-IP system, hardware-related alerts, including those for power supply units (PSUs), fans, and chassis components, are primarily logged in the Local Traffic Manager (LTM) log file.

Log Location: The file path is /var/log/ltm.

PSU Alert Messages: When a power supply fails, experiences an outage, or is unplugged, the chmand (Chassis Manager) or system_check processes log specific error codes to this file. For example, you may see messages like 010d0006:0: Chassis power supply has experienced an issue or VINPUT=bad.

Troubleshooting: Administrators can use the command grep -i "power supply" /var/log/ltm to quickly filter for PSU-related events.

Other Logs: * /var/log/kern.log typically contains low-level kernel and driver messages.

/var/log/audit tracks administrative changes and commands executed by users.

/var/log/daemon.log contains messages from various system background services but is not the primary location for hardware sensor alerts.
