Description: Cisco UCS equipment:FexSystemStats:kernelMemFreeMin managed object property

What is cucsEquipmentFexSystemStatsKernelMemFreeMin?

This read-only Gauge32 field is the 'kernelMemFreeMin' property of the 'FexSystemStats' managed object in Cisco UCS Manager's equipment-inventory schema capturing the lowest amount of free kernel memory seen in the window. The lowest free-memory figure in the window is the number that matters most operationally, since it shows how close the FEX's control-plane OS came to running out of memory at its worst moment. A KernelMemFreeMin of 8MB is the kind of reading that would prompt an admin to schedule a FEX reload before the control plane hits an out-of-memory condition.
