Question:

I have MAC OS devices modeled in Spectrum that are getting the "HIGH AGGREGATE MEMORY UTILIZATION". How is the memory utilization computed for devices that support the UC Davis mib?

Answer:

Spectrum uses the following formula to calculate memory utilization for devices that support the UC Davis mib:

((memTotalReal - (memAvailreal + memCached + memBuffer)) / memTotalReal) * 100 

 

memAvailReal attribute id 0x3d00ae 

memTotalReal attribute id 0x3d00ad 

memCached attribute id 0x3d00b7 

memBuffer attribute id 0x3d00b6 

 

These attributes exist on the UCDavisSNMPApp model associated with the device model.
