Oracle VM metrics

The following metrics are available for Oracle Virtual Machine systems:

Oracle VM Host Configuration

The Oracle VM Host Configuration metric group provides configuration information for Oracle VM hosts.

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

Metric group: Oracle VM Host Configuration

Metric and available units	Description

Cores per Socket	Number of cores per socket.
Sockets per Node	Number of sockets per node.
Nodes	The number of NUMA cells on this host.
Clock Rate	The expected CPU frequency in MHz.
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.

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 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.

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.

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.

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.

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	Input errors.
Out Errors	Output errors.
In Bytes	The number of bytes received by the network interface card.
Out Bytes	The number of bytes transferred by the network interface card.
