Memory Page
The Memory page contains several charts.
To open the network page

-
Click Activity Summary | Memory.
Charts on the Memory page
Notes:
- Every chart has a legend (list of symbols) to its right that describes the various series (line graphs) on the chart.
- Click an item in the legend to highlight its series (line) in the chart. Click a second time to return the series to its normal appearance.
- Move the mouse pointer over an item in the legend to view the current value for that series within the chart.
| Chart | Description |
|---|---|
| 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. |
| Paging |
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. |
