Total Memory | The maximum allowed memory, in kilobytes. |
State | The run state of the domain. |
UUID | The UUID of this domain. |
MAC Address | The first MAC Address that can be found; can be used to identify the domain. |
Credit Weight | A numerical value representing the CPU time allocation assigned to the domain. |
Credit Cap | A numerical value representing the maximum CPU time the domain can use. |
Operating System | The name of the operating system that is running on the virtual machine or domain. |
Display Name | The name of the virtual machine as displayed from OVM Manager. |
Oracle VM Domain Statistics
The Oracle VM Domain Statistics metric group provides statistics for Oracle VM domains.
The following table describes the Oracle VM Domain Statistics metric group.
Metric group: Oracle VM Domain Statistics
Metric and available units | Description |
---|---|
Domain Name | Set when the domain is created and has no real correlation to the network name. |
Domain ID | The domain number this guest or domain is running as; provides a way to correlate this domain with a Oracle VM Domain Configuration. |
Total Memory | The memory, in kilobytes, allocated to the domain (essentially a duplicate from Domain Configuration). |
Used Memory | The memory, in kilobytes, used by the domain. |
Free Memory | The amount of memory still available on the domain; this is a calculated field. |
CPU Time | T The amount of time, in seconds, the CPU was used by the VM. |
Uptime | The amount of time since the virtual system was last booted. Not valid for a virtual system snapshot. |
Memory Ratio | The ratio of Used Memory to Total Memory; this is a calculated field. |
Memory Utilization | The Memory Ratio expressed as a percentage. |
Oracle VM VCPU Statistics
The Oracle VM VCPU Statistics metric group provides virtual CPU statistics for Oracle VM systems.
The following table describes the Oracle VM VCPU Statistics metric group.
Metric group: Oracle VM VCPU Statistics
Metric and available units | Description |
---|---|
VCPU ID | The virtual CPU identifier. |
Domain ID | The domain number this guest or domain is running as; provides a way to correlate this domain with a Oracle VM Domain Configuration. |
Domain Name | Set when the domain is created and has no real correlation to the network name. |
CPU Time | The percentage of time that the VCPU was busy. |
Real CPU ID | The physical CPU identifier. |
State | The state of virtual CPU. |
Oracle VM Disk Statistics
The Oracle VM VCPU Statistics metric group provides virtual CPU statistics for Oracle VM systems.
The following table describes the Oracle VM VCPU Statistics metric group.
Metric group: Oracle VM Disk Statistics
Metric and available units | Description |

Domain ID | The domain number this guest or domain is running as; provides a way to correlate this domain with a Oracle VM Domain Configuration. |
Domain Name | Set when the domain is created and has no real correlation to the network name. |
Read Bytes | The average number of bytes read from the disk. |
Write Bytes | The average number of bytes written to the disk. |
Total I/O | The average number of Read Bytes plus Write Bytes. |
Total I/O Kbs | The average I/O rate, expressed in kilobytes per second. |
Read Requests | The total number of read requests. |
Write Requests | The total number of write requests. |
Total Requests | The sum total of read and write requests. |
Oracle VM Network Interface Statistics
