Memory and System Memory in the AS

Product Line

SmartStruxure Solution

Environment

StruxureWare Building Operation site

Cause

What is the definition of the two different memory types shown in the AS? It is not clearly defined in the documentation.

In various places, one can see Memory and System Memory, or even add a column to show. 

Resolution

For the AS, System Memory is the RAM used by the AS Linux OS. The rest of the memory is what is being used for the processes, such as programs, trends, etc.

Memory is the amount of memory consumed by the AS (nsp_servers application), system memory is that used by the Linux OS, however there is much debate about how this is calculated and allocated, so too much should not be read into this, it is there primarily for developers.
