Configuring Memory Thresholds

You can set the memory thresholds that are used to trigger events and set whether the operating system should kill processes if it cannot allocate memory.

For more information, see the Cisco Nexus 9000 Series NX-OS System Management Configuration Guide:

Verifying a DME Configuration

The following table contains the distinguished name (DN) for each managed object (MO) in the DME payload. Issue a GET request using the DN to verify the configuration was posted or to get information about the configured properties of a particular object.

MO	DN
platformEntity	sys/pltfm
platformSysMemTh	sys/pltfm/sysmemth

platformSysMemTh Properties

The following table contains information about the platformSysMemTh properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
memThCritical	platform:SysMemThVal (scalar:Uint32)	Critical System Memory Threshold	RANGE: [50 , 100] DEFAULT: 50
memThMinor	platform:SysMemThVal (scalar:Uint32)	Minor System Memory Threshold	RANGE: [50 , 100] DEFAULT: 50
memThSevere	platform:SysMemThVal (scalar:Uint32)	Severe System Memory Threshold	RANGE: [50 , 100] DEFAULT: 50
