2.1 Status Overview

The dashboard displays information about each server pool, Oracle VM Server summary, and the number of Oracle VM Servers that are running or stopped. Note that information is not displayed for Oracle VM Servers or virtual machines that are not assigned to a server pool.

A green, yellow, or red status is displayed for each server pool:

Green: All Oracle VM Servers and virtual machines are in a normal state.

Yellow: One or more Oracle VM Server(s) has a CPU or memory utilization above the specified limit. One or more virtual machine(s) has a CPU utilization above the specified limit. One or more file systems has a utilization above the specified limit. Click the hyperlink to view detailed information. See Section 2.1.2, “Detailed Information Dialog” for more information on this dialog.

Red: One or more Oracle VM Server(s) has unacknowledged events indicating a down state that needs operator attention. Click the hyperlink to view detailed information.

The information displayed here is dependent on the statistics collection facility being enabled. If this facility is disabled, a message is displayed to indicate that statistics for health monitoring are unavailable and that the statistics collection facility must be enabled if you wish to use this feature in the future. More information on enabling and configuring the statistics collection facility is available in Section 7.4, “Preferences”. Also 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 and file system statistics intervals that are configured for this service.

2.1.1 Toolbar

This section contains the toolbar options in the Status Overview subtab of the Health tab.

Display Parameters

The Display Parameters options allow you to control how the information in the Status Overview subtab is displayed. The following options are available:

  • Number of Columns: Sets the number of columns displayed. Select between 1 to 10 columns.

  • Refresh Interval: Sets the interval between which the statistics are refreshed. Select 30 seconds, 1, 2, 5 or 10 minutes. The default setting is 5 minutes.

  • Order By: Sets the sort order for the information. Sort by Total Servers Down, Total VMs Down, or Alphabetically.

These settings are persistent across each user login, as described in Section 1.3, “User Preference Persistence”.

Utilization Thresholds

The Utilization Thresholds options at the top of the panel allows you to set the parameters available to trigger different health warnings. The following options are available:

  • Server Processor %: Sets the percentage of processor utilization on an Oracle VM Server to trigger a warning. The default setting is 70%. Note that this setting does not apply to Unassigned Servers.

  • Server Memory %: Sets the percentage of memory utilization on an Oracle VM Server to trigger a warning. The default setting is 95%. Note that this setting does not apply to Unassigned Servers.

  • VM Processor %: Sets the percentage of processor utilization for a virtual machine to trigger a warning. The default setting is 70%. Note that this setting does not apply to Unassigned Virtual Machines.

  • File System %: Sets the percentage of file system utilization for an Oracle VM Server to trigger a warning. The default setting is 95%.

These settings are persistent across each user login, as described in Section 1.3, “User Preference Persistence”.

File System Utilization Summary

The File System Utilization Summary toolbar provides two links to allow you to view information about file systems that are either above or below the utilization threshold. The link text indicates the number of file systems that are being monitored and the number of these that are either above or below the utilization threshold. Clicking on either link provides a listing of the file systems that match the criteria specified by the link text.

The information displayed in the resulting dialog lists the file systems in a tabulated format. The following columns are presented:

  • Name: The name of the file system, as stored in Oracle VM Manager.

  • Storage Device: The name of the storage device where the file system is located. This column is not displayed if the storage type is a file server.

  • Total Size (GiB): The total size of the file system measured in gibibytes.

  • Available Size (GiB): The amount of free or available space on the file system measured in gibibytes.

  • Used Size (GiB): The amount of space that is currently used on the file system measured in gibibytes.

  • Utilization (%): The calculated percentage of space currently used on the file system.

  • Last Refreshed: The date and time when the last file system statistics were collected and refreshed.

Note that if System Statistics Collection is disabled as described in Section 7.4, “Preferences”, a message notifying you that the service is disabled and not available for health monitoring is displayed in this toolbar instead.

2.1.2 Detailed Information Dialog

When a Yellow or Red status is shown for a server pool in the Status Overview dashboard, the message appears as a hyperlink that opens a dialog containing more detailed information to describe the incident that needs attention. This dialog provides facilities to discover events leading up to an incident.

The dialog toolbar includes various icons to help you resolve any issues. Select the item in the table that you wish to act on. Click the Events icon Events icon to view more information about the events within the log related to the item that you are working with. You may need to acknowledge particular events in order to resolve an issue. See Section 1.10.4.2, “Events Perspective” for information on acknowledging events.
