This section provides a detailed description of the monitoring data collected for each target type. It also explains how this information is displayed in various panels, which are combined to form the Oracle VDI target pages.
Metrics collection is an asynchronous operation. Live data, such as desktop states or CPU load, are updated every 5 or 15 minutes by default depending on their importance. This means that related targets, meaning parent or child targets, may show different values at the same point in time. Configuration data is collected every 24 hours. The collection schedule can be altered by the Oracle Enterprise Manager administrator, as described in "Collection Intervals" in Section 4.3, “Metrics Collection”.
This section provides a detailed description of the different panels that appear in multiple target pages. Panels that are specific to one target page, are described in the target page overviews in the sections that follow.
- Summary
Every Oracle VDI target page has a Summary panel. It contains general configuration information and, if applicable, hardware configuration details of the host. Click Oracle VDI Manager to access the administration tool for the Oracle VDI Center.
- Desktop States
In the Desktop States panel, current information for the desktop states is displayed as a pie chart. For each desktop state, a total count is shown in brackets in the legend. Possible desktop states are: available, used, idle, reserved and unresponsive.
- Desktop States History
In the Desktop States History panel, the state of desktops is shown in a stacked area chart on a time scale. The number of desktops in each state are stacked, so that the highest value represents the total number of desktops in the company. The chart shows the history of desktop states over a period of time. The time period can be modified by zooming in or out. You control the zoom level by clicking the magnifying glass icon to the left of the scroll bar or by dragging the edges of the slider on the scroll bar.
Desktops are in an available, used, idle, reserved or unresponsive state, and individual graphs are displayed if you move the mouse pointer over the colored area or legend item.
Click Table View to display the chart values in a pop-up window as a table, where each row represents a measure recorded at a specific time and date.
- Machine States
In the Machine States panel, current information for the virtual machine states is displayed on a horizontal bar with a percentage scale. For each virtual machine state, a total count is shown in brackets in the legend. Possible machine states are: running, not running, unknown and error.
- Desktop Distribution by CPU Utilization
In the Desktop Distribution panel, the total number of desktops is broken down by the percentage of CPU load. The diagram displays the number of desktops for each 10% interval of CPU activity.
- System Utilization
The System Utilization line chart displays four major performance parameters of a host or a group of hosts: CPU usage, memory usage, network read bandwidth and network write bandwidth. The chart shows the history of these parameters over a period of time. The time period can be modified by zooming in or out. You control the zoom level by clicking the magnifying glass icon to the left of the scroll bar or by dragging the edges of the slider on the scroll bar.
The values used to plot the line graphs are typically averages based on metrics collected from different servers. The highest value among the metrics from all servers is called the top value, and the most recently collected top values are displayed below the chart.
The target type determines whether top values are displayed. For example, CPU utilization always has a top value because a single host likely has multiple cores. However, in a single host configuration there is no top value for memory because it is treated as one global entity.
NoteIncidents and problems related to these metrics are triggered by top values that exceed a threshold and not by their totals or averages.
Individual graphs are displayed if you move the mouse pointer over the line or legend item.
Click Table View to display the chart values in a pop-up window as a table, where each row represents a measure recorded at a specific time and date.
- File System Utilization
The File System Utilization line chart displays two major disk activity parameters of a host or a group of hosts: file system usage and disk busy percentage. The chart shows the history of these parameters over a period of time. The time period can be modified by zooming in or out. You control the zoom level by clicking the magnifying glass icon to the left of the scroll bar or by dragging the edges of the slider on the scroll bar.
Individual graphs are displayed if you move the mouse pointer over the line or legend item.
Click Table View to display the chart values in a pop-up window as a table, where each row represents a measure recorded at a specific time and date.
- Incidents and Problems
The Incidents and Problems table shows any event from a target or resource that exceeds a threshold, stops working, or disappears from monitoring. For each event, the default table shows when it occurred and which monitoring target is impacted, provides a short description, and indicates the severity. See Section 3.3, “Predefined Incidents and Problems” for additional information.
In the View menu, in the top-left corner of the panel, you can configure which columns are displayed in the table.
Warnings, which are the lowest severity category, are not escalated from child targets to parent targets.
Click the event description in the Summary column to display all details of the incident or problem in Oracle Enterprise Manager's built-in Incident Manager.
The Oracle VDI Center is the main target node in the Target Navigation panel, to which all other Oracle VDI targets are hierarchically connected. Its monitoring page is designed to provide an overview of the most important metrics and configuration data, enabling you to quickly determine the general status of the entire Oracle VDI environment. Several areas of this monitoring page provide links to child targets, such as companies and desktop providers, which enable you to drill-down quickly into the details of components that require investigation.

An Oracle VDI host is a host that runs the Oracle VDI software, and manages user connections to virtual desktops. Although single-host configurations are possible, Oracle VDI Centers configured for high-availability and failover always consist of multiple hosts. For the desktop sessions as well as for the Oracle VDI configuration, an Oracle VDI host runs a number of services. These services and desktop sessions constitute the most important monitoring data provided specifically on the Oracle VDI host target page.

The Enterprise Manager Plug-in for Oracle VDI does not create new target pages for desktop provider types other than Oracle VDI VirtualBox. However, these other desktop provider types do appear in the Target Navigation pane as child targets of the Oracle VDI Center, and there is monitoring data available for each of them, as collected and presented by Oracle Enterprise Manager.
As a minimum, these target pages display the overall status of the desktop provider, along with a table of incidents and problems. The monitoring targets that are presented this way are:
Microsoft Hyper-V desktop provider
VMware vCenter desktop provider
Microsoft Remote Desktop Services provider
Sun Ray Kiosk desktop provider
Generic desktop provider
