Oracle VM Server Monitoring - Virtual Machines


The virtual machines (VMs) present in an Oracle VM (OVM) server are monitored 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. 

ParameterDescription
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.
