The data that you can check in the operating system monitor for memory management includes data for the swap space and paging as well as the physically available memory. The following values are measured:
High paging rates indicate that the main memory is too small for the running processes. Measures that you can take are to extend the main memory, to move processes to other host systems, and to delay memory-intensive program runs to times of lower system workload.
On Windows platforms (unlike UNIX platforms), the system performs paging out as a precautionary measure even when space is not required in the working memory, meaning that this value is irrelevant and you should only consider the paging in rate. Under UNIX, on the other hand, Page_Out is the critical value for evaluating the paging.
In the periods Previous Hours and History, only the free swap space and the utilization of the swap space as a percentage are displayed.
Not all types of swap space are available on all operating systems. For this reason, in some cases, the actual swap space size corresponds to the configured and maximum swap space.
