Oracle VM Server Monitoring - Virtual Machines

The virtual machines (VMs) present in an Oracle VM (OVM) server are monitored by Applications Manager's Oracle VM monitoring based on the parameters or the attributes listed below. These attributes provide information about the functioning of the VMs. You can also configure thresholds to the numerical attributes of the VMs based on these details.

The Availability tab lists all the virtual machines present in the OVM servers and their availability status. You can also view Availability history of the virtual machines for the past 24 hours or 30 days.
The Performance tab shows some key performance indicators of the virtual machine including CPU Utilization, Memory Utilization, Disk I/O Utilization and Network Utilization along with heat charts for these attributes. This tab also shows the health status and events for the past 24 hours or 30 days.
The List view displays all the virtual machines discovered under each OVM server. This view provides an overall idea of the availability and health of all the virtual machines. The list view also enables you to perform bulk admin configurations. Click on the individual virtual machines listed to view detailed VM metrics.
The Top Virtual Machines tab shows graphs for the top CPU consumers, top memory consumers, top disk I/O consumers, and top network consumers of the OVM server. This section enables you to find out which virtual machines are consuming your server resources and take action accordingly.

Click on the individual monitors listed in the Availability tab to view detailed performance metrics of the corresponding virtual machine. These metrics are categorized into four separate tabs for easy understanding.

Overview

This tab provides a high-level overview of virtual machines running under OVM servers.

Parameter	Description
CPU & Memory Utilization
CPU Utilization	The amount of CPU currently being used by the virtual machine. (%)
Memory Utilization	The amount of memory currently being used by the virtual machine. (%)
Total Memory	The total amount of memory allocated to the virtual machine. (GB)
Used Memory	The amount of memory used by the virtual machine. (GB)
Free Memory	The remaining amount of memory available for the virtual machine. (GB)
Disk & Network Usage
Read Bytes	The number of bytes read from the disk by the virtual machine. (MB/Min)
Write Bytes	The number of bytes written to the disk by the virtual machine. (MB/Min)
Bytes Received	The number of bytes sent over the network interface by the virtual machine. (MB/Min)
Bytes Transmitted	The number of bytes received over the network interface by the virtual machine. (MB/Min)

Disk

This tab provides details about disk storage of virtual machines running under Oracle VM Servers.

Parameter	Description
Name	The name of the virtual disk used by the virtual machine.
Type	The type of the virtual disk used by the virtual machine.
Size	The size of the virtual disk used by the virtual machine. (GB)
Repository	The name of the repository used by the virtual machine.
Absolute Path	The absolute path of the image file that represents the virtual disk.
Mounted Path	The mounted path of the file that represents the virtual disk.

Network

This tab provides details about network interface of virtual machines running under Oracle VM servers.

Parameter	Description
Name	The name of Network Interface Card (NIC) used by the virtual machine.
MAC Address	The Media Access Control (MAC) address of the virtual Network Interface Card (NIC) used by the virtual machine.
Ethernet Network	The IP address of the Ethernet network of the virtual Network Interface Card (NIC) used by the virtual machine.

Configuration

This tab provides the configuration details of virtual machines running under Oracle VM servers.

Parameter	Description
Host Name	The host name of the virtual machine.
ID	The Universally Unique Identifier (UUID) of the virtual machine.
IP Address	The IP address of the virtual machine.
OS Type	The name of the operating system installed on the virtual machine.
State	The current state of the virtual machine.
Total CPU(s)	The number of CPUs assigned to the virtual machine.

Guest OS Monitoring

Guest OS monitoring allows to monitor the Processes, Services, Event Logs(if windows VM) in a Virtual Machine monitor. To enable this for a VM monitor, Go to VM Monitor Details page -> Click Monitor Actions -> Click 'Configure OS' option. Provide the server credentials to connect with the OS. Once configured, under the Process / Services tab, the option to Add/Remove the process will be shown. By using this option, we can add process / services for monitoring.
