Module: CISCO-UNIFIED-COMPUTING-SW-MIB

OID (symbolic): CISCO-UNIFIED-COMPUTING-SW-MIB::cucsSwSystemStatsHistKernelMemFreeMin

OID (numeric): 1.3.6.1.4.1.9.9.719.1.46.29.1.28

Node type: OBJECT-TYPE

Type: Gauge32

Access: read-only

Description: Cisco UCS sw:SystemStatsHist:kernelMemFreeMin managed object property

What is cucsSwSystemStatsHistKernelMemFreeMin?

This Gauge32 reports the lowest amount of free kernel memory recorded on the switch during this SystemStatsHist collection interval. An admin relies on this minimum to catch the worst moment of memory pressure within the interval, which the average alone could mask. For example, a SystemStatsHist sample whose min free kernel memory dips close to zero would be a strong signal to an admin that the switch briefly came under severe memory pressure.

Examples
