2.3 Server and VM Statistics

Oracle VM Manager periodically collects vital statistics such as memory and CPU usage. Select the Server and VM Statistics subtab of the Health tab to view historical statistics for your Oracle VM Servers and virtual machines. Note that statistics collection is an asynchronous and periodic service, so the information displayed on the Health tab is not in real time, but is dependent on the statistics collection interval that is configured for this service. Furthermore, the historical period over which you are able to view this data is limited to the statistics collection hold time value configured for this service. Views of different statistical information are provided by clicking on elements in the navigation pane.

Note

You can disable statistics collection in Oracle VM Manager from the Preferences subtab of the Reports and Resources tab. For more information about disabling statistic collection, and the implications of doing so, see Section 7.4, “Preferences”.

2.3.1 Toolbar

The navigation pane toolbar on the Statistics subtab of the Health tab, includes the following item:

2.3.2 Server Pools Folder

By clicking on the Server Pools folder in the navigation tree in the navigation pane, you can view the following statistical information about server pools:

  • Server Pool Name: The name of the server pool. The following columns are available, presenting information for each server pool:

    • Processors:

      • Server Total: Total number of processors of all Oracle VM Servers in the server pool.

      • VM Allocated: Total number of processors available for use by virtual machines in the server pool.

      • VM Used: Total number of processors in use by virtual machines in the server pool.

    • Memory (GiB):

      • Total: Total amount of memory, in GiB, in the server pool.

      • Configured: Total amount of memory, in GiB, available for use by virtual machines in the server pool.

      • Used: Total amount of memory, in GiB, in use by virtual machines in the server pool.

2.3.3 Server Pool Item

By expanding the Server Pools node in the navigation pane, you can click on individual server pools. Clicking on a server pool displays the following statistical data:

  • Server Name: The name of the Oracle VM Server. The following columns are available, presenting information for each Oracle VM Server:

    • Processors:

      • Utilization (%): The percentage of total processors in use on the Oracle VM Server.

      • Total: The number of processors available on the Oracle VM Server.

    • Memory (GiB):

      • Utilization (%): The percentage of total memory in use on the Oracle VM Server.

      • Total: The memory, in GiB, on the Oracle VM Server.

      • Usable by VMs: The memory, in GiB, available for use on the Oracle VM Server.

        Note

        Usable memory is a calculated value. As a result it is possible for the sum of the usable memory value and the used memory value to be greater than the total memory.

      • Used: The memory, in GiB, in use by the operating system, its processes, and virtual machine management.

    • Last Refreshed: The date and time when the last server statistics were collected and refreshed. This field may appear blank if no statistics have been collected. This may occur if the server is stopped.
