Issue
Memory and System Memory in the AS
Product Line
EcoStruxure Building Operation
Environment
- Building Operation Automation Server
- Building Operation Automation Server Premium
- Building Operation Automation Server Bundled
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.
