VirtualBox Manager includes the following tools for viewing runtime information and changing the configuration of virtual machines.
VM Activity Overview. Displays an overview of performance metrics for all running VMs.
Session Information Dialog. Displays configuration and runtime information for the selected guest system.
The VM Activity Overview tool displays several performance metrics for all running virtual machines and for the host system. This provides an overview of system resources used by individual virtual machines and the host system.
To display the VM Activity Overview tool, do the following:
Go to the global Tools menu and click Activities. The VM Activity Overview window is shown.
To show metrics for all virtual machines, including those that are not running, right-click on the list of virtual machines and select List All Virtual Machines.
To configure the set of metrics to be shown, click Columns in the toolbar. You can then sort the list of virtual machines by a particular metric.
To see more performance information for a virtual machine, select the VM name and click VM Activity in the toolbar. The VM Activity tab of the Session Information dialog is shown, see Section 1.20.2, “Session Information Dialog”.
The Session Information dialog includes multiple tabs which show important configuration and runtime information for the guest system. The tabs of the dialog are as follows:
Configuration Details. Displays the system configuration of the virtual machine in a tabular format. The displayed information includes details such as storage configuration and audio settings.
Runtime Information. Displays runtime information for the guest session in a tabular format similar to the Configuration Details tab.
VM Activity. Includes several time series charts which monitor guest resource usage including CPU, RAM, Disk I/O, and Network. Note that the RAM chart requires the Guest Additions to be running on the guest system. The VM Activity tab can also be accessed directly from the VM Activity Overview tool. See Section 1.20.1, “VM Activity Overview”.
Guest Control. Details of processes used by the Guest Control File Manager. See Section 4.8, “Guest Control File Manager”.
To display the Session Information dialog, select Machine, Session Information in the guest VM.
