Charts on the Memory page
|Physical||The Physical Memory chart shows the total physical memory (RAM) on the Unix host, and the amount of physical memory that is currently free.|
|Virtual||The Virtual Memory chart shows the total amount of memory in use on the Unix host. This includes physical memory plus space in the paging files. A steady increase in virtual memory usage can indicate that a process on the system has a memory leak.|
The Paging chart shows the rate at which pages are being swapped in and out of memory. The chart displays three data series:
A sustained high rate of paging can cause problems with overall system degradation due to disk thrashing and CPU load.
Note: Scan rate is not available for Linux.
|Cache||The Cache chart shows the percentage of recent file requests (read and write) that are satisfied by the memory cache, and that do not require a request to the paging areas on disk.|
