Abstract: Aspects for detecting environmental faults in redundant components of a computer system are described. In an exemplary method aspect, the method includes monitoring system environment conditions, including a status for redundant power supply and cooling components. The method further includes registering a failure condition with an appropriate error type when a monitored system environment condition exceeds a design threshold, and utilizing the registered failure condition as data in an architected error log.

Abstract: Method and system aspects for monitoring computer system operations are provided. A computer system including a processor, the processor supporting firmware and a running operating system, and a service processor coupled to the processor, is monitored by initiating surveillance of the computer system in the firmware when an architected function occurs in the operating system. Monitoring additionally includes providing a pulse indicator from the firmware to the service processor and determining a status of computer system operations with the service processor based on a frequency of the pulse indicator.
