Total Memory

The memory size in kilobytes (actual physical RAM on the machine).

Active CPUs

The number of active CPUs.

CPU Model

A string indicating the CPU type (for example, i686).

Scheduler

The name of the system scheduler.

Hypervisor Version

The hypervisor version number.

Oracle VM Domain Configuration

The Oracle VM Domain Configuration metric group provides configuration information for Oracle VM domains.

The following table describes the Oracle VM Domain Configuration metric group.

 Metric group: Oracle VM Domain Configuration

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 numbers that this guest or domain is running as.

Available VCPUs

The maximum number of virtual CPUs the guest was booted with.

Online VCPUs

The number of virtual CPUs currently in use by the domain.

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 WeightA numerical value representing the CPU time allocation assigned to the domain.
Credit CapA 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 NameThe 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.

UptimeThe 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 IDThe physical CPU identifier.
StateThe 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

Disk Name

The name of the disk as reported by the Oracle VM.

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

The Oracle VM VCPU Statistics metric group provides network interface statistics for Oracle VM systems.

The following table describes the Oracle VM Network Interface Statistics metric group.

Metric group: Oracle VM Network Interface Statistics

Metric and available unit

Description

Interface Name

The Network Interface name, as returned by the Oracle VM.

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.

Mac Address

The MAC (48-bit) address of the Ethernet network card.

In Packets

Packets received.

Out Packets

Packets sent.

In Errors
