High memory alert

[SAPSupport]

Hello Team,

We are received multiple high memory alert from frun and while checking managed system there is enough space. For example  alert received due to Used Memory [%]

We are using Linux template and we want to monitor only physical memory. How can we achieve this. is there any customize metric available for  only monitor physical memory used %

Free Memory metric from Linux template is measuring available physical Memory :

This the amount of physical memory free on the host in gigabyte.

The metric returns data in GB.

However this metric is not capable of measuring in %, but you have metric Free Memory [%]

This the amount of physical memory free on the host in percentage of total memory available.

Dear customer,

Metric "Used Memory[%]" is the amount of physical memory used on the host in percentage of total memory available.

This value is collected by SDA via saphostctrl GetCIMObject webmethod, thus you could use following command to verify the correctness of the received value:

./saphostctrl -function GetCIMObject -enuminstances "SAP_MetricValue?MetricDefinitionId=OS.FreePhysicalMemory&MetricDefinitionId=OS.AvailablePhysicalMemory&MetricDefinitionId=OS.TotalVisibleMemorySize"

Used Memory [%] = 100-(OS.AvailablePhysicalMemory*100/OS.TotalVisibleMemorySize)
