Free physical memory

The free physical memory Monitor allows you to identify a memory leak early by establishing a threshold and properly reacting to any problems before a crash occurs.

Running out of free physical memory is a reason for server performance degradation. Some systems use secondary storage as virtual memory, moving the least-used data from the physical memory and retrieving it back when it is required. Besides the fact that secondary storage is much slower, such swapping leads to file system fragmentation, which contributes to an even greater decrease in server performance.
When there is little RAM left, you may want to consider optimizing the way physical memory is used by the OS and other software. If you are not able to reduce the amount of used physical memory, then you should add more RAM to the server.
A memory leak is a common problem for server software. It usually happens due to poor design, when an application does not properly discard unused objects from the main memory. The amount of memory constantly increases until there is no memory left for new objects, and then the application crashes.

Note: For all types of local resources monitors, you need to have Anturis Private Agent downloaded, installed, and running on your machine, in order to configure the monitoring.

Adding a free physical memory monitor

Before proceeding, please ensure that you have created the component and your Anturis Private Agent for Windows or Linux is running.
  1. On the Component page, click Add/Remove Monitors > Add Custom Monitor.
  2. Select the Local Resources monitors tab and Hardware sub tab view.
  3. Select Free physical memory Monitor and click Next.
  4. Select a period of time from the Monitor Period drop-down menu.
  5. Select the agents (servers) from the list.
  6. Click Next.
  7. Under Free host memory threshold, set the appropriate values for an Error threshold and Warning threshold.
  8. Enter a Monitor Name and set consecutive measurements.
  9. Click Next.
  10. On the Monitor test result step, click Next when the test is passed.
  11. Click Finish.

To manage your monitor, click View/Edit parameters.
