Apparatuses, methods, systems, and program products are disclosed for analytics-based anomaly detection. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to receive measurement data for a component of a device, determine a compression rate of the received measurement data by applying a compression algorithm to the measurement data, and generate an alert indicating a possible anomaly in an operation of the component represented by the measurement data in response to the determined compression rate satisfying a threshold compression rate for the at least one condition of the component.

Analytics-based anomaly detection

A baseboard management controller (BMC) installed in a server or other hardware device may perform operations to monitor and safeguard metering data for one or more hardware component of a server that includes the BMC. The BMC may periodically transmit a metering data message over a network to an event destination, where the metering data message includes the utilization levels of the hardware component during a period of operation. In response to detecting a loss of communication with the event destination, the BMC may perform lossy compression of the monitored utilization levels for the hardware component, wherein the lossy compression produces a utilization value that is representative of the monitored utilization levels, but uses less data storage capacity. The utilization value may be transmitted to the event destination instead of the monitored utilization levels in response to determining that communication with the event destination has been reestablished.

A system and method are provided for passing a data file from a software utility to a service processor. The method includes loading, using a processor, an interrupt handler and runtime code during initialization of a computer before booting an operating system; requesting, using a processor, that the operating system transfer a data file via an interface; and transferring, using a processor, the data file to an area accessible to the runtime code. The method further includes requesting, using a processor, that the interrupt handler pass the data file to a service processor. Still further, the method includes passing, using a processor, the data file from the accessible area to the service processor via a memory-mapped input/output window of the service processor, wherein the data file is transferred to the service processor without waiting for a system reboot.

Effects of a physical memory fault are mitigated. In one example, to facilitate mitigation, memory is allocated to processing entities of a computing environment, such as applications, operating systems, or virtual machines, in a manner that minimizes impact to the computing environment in the event of a memory failure. Allocation includes using memory structure information, including, information regarding fault containment zones, to allocate memory to the processing entities. By allocating memory based on fault containment zones, a fault only affects a minimum number of processing entities.
