The metrics reported by the guest (as opposed to inferred from outside)

Fields for class: VM_guest_metrics

Field	Type	Qualifier	Description
`can_use_hotplug_vbd`	`tristate_type`	RO/runtime	The guest’s statement of whether it supports VBD hotplug, i.e. whether it is capable of responding immediately to instantiation of a new VBD by bringing online a new PV block device. If the guest states that it is not capable, then the VBD plug and unplug operations will not be allowed while the guest is running.
`can_use_hotplug_vif`	`tristate_type`	RO/runtime	The guest’s statement of whether it supports VIF hotplug, i.e. whether it is capable of responding immediately to instantiation of a new VIF by bringing online a new PV network device. If the guest states that it is not capable, then the VIF plug and unplug operations will not be allowed while the guest is running.
`disks`	`(string -> string) map`	RO/runtime	Removed. This field exists but has no data.
`last_updated`	`datetime`	RO/runtime	Time at which this information was last updated
`live`	`bool`	RO/runtime	True if the guest is sending heartbeat messages via the guest agent
`memory`	`(string -> string) map`	RO/runtime	Removed. This field exists but has no data. Use the memory and memory_internal_free RRD data-sources instead.
`networks`	`(string -> string) map`	RO/runtime	network configuration
`os_version`	`(string -> string) map`	RO/runtime	version of the OS
`other`	`(string -> string) map`	RO/runtime	anything else
`other_config`	`(string -> string) map`	RW	additional configuration
`PV_drivers_detected`	`bool`	RO/runtime	At least one of the guest’s devices has successfully connected to the backend.
`PV_drivers_up_to_date`	`bool`	RO/runtime	Deprecated. Logically equivalent to PV_drivers_detected
`PV_drivers_version`	`(string -> string) map`	RO/runtime	version of the PV drivers
`uuid`	`string`	RO/runtime	Unique identifier/object reference
