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

What is cucsEquipmentFexSystemStatsKernelMemFreeMax?

This read-only Gauge32 field is the 'kernelMemFreeMax' property of the 'FexSystemStats' managed object in Cisco UCS Manager's equipment-inventory schema capturing the highest amount of free kernel memory seen in the window. The highest free-memory figure in the window is effectively the best-case memory headroom the FEX's control plane had, useful as a ceiling to compare the more concerning minimum figure against. A KernelMemFreeMax of 62MB against a KernelMemFreeMin of 41MB in the same window shows real memory pressure building and easing within a single day.
