Virtual Machine

Virtual Machine
Object	Counter	Instance	Definition
VMGuest-disk	commands/sec	Datastore name: Virtual disk name	Total number of SCSI commands issued to the virtual disk.
VMGuest-disk	commands/sec	_Total	Rolled up total IOPS (reads+ writes per second) for all vmhba storage connections in this virtual machine.
VMGuest-disk	commandsFailed	_Total	Number of aborted and reset SCSI commands in the last interval.
VMGuest-cpu	cpuCoStopPct	_Total	Time the VM is ready to run but is unable due to co-scheduling constraints.
VMGuest-cpu	cpuIdlePct	_Total	Percent of time that the CPU was idle for this virtual machine during the last interval. For ESX 3.x systems, this value is in milliseconds.
VMGuest-cpu	cpuLatencyPct	_Total	Percent of time the VM is unable to run because it is contending for access to the physical CPU(s).
VMGuest-cpu	cpuReadyPct	_Total	Percentage of time during the last sample that the virtual machine CPU resources were in the ready state.
VMGuest-cpu	cpuSwapWaitPct	_Total	Percentage of the time during the last sample spent waiting for swap-in.
VMGuest-cpu	cpuUsageMHz	_Total	CPU usage (in MHz) over the interval of collection.
VMGuest-cpu	cpuUsedPct	_Total	Percentage of the potential physical server CPU time that this virtual machine was busy during the last interval. For example, consider an 8-core vSphere host with a single 2-core VM. If each core is rated at 3.000 MHz and the VM consumes an average of 5.400 MHz over the interval, the cpuUsedPct will be 90% (since 6,000 is the maximum that a 2-core VM could consume). 5.400 MHz represents 23% of the vSphere host total capability of 24,000 MHz. See cpuUsedPct for this server percentage.
VMGuest-cpu	cpuWaitPct	_Total	Percentage of time during the last sample that the virtual machine CPU resources were in the 'wait' state. For example, on a physical server with 2 CPU threads, during a 300 second interval 600 seconds of CPU resources are available. If the VM was in a "wait" state for 60 seconds the cpuWaitPct will be 10%.
VMGuest-disk	diskLatency	_Total	Highest latency value across all disks used by the VM.
VMGuest-net	droppedPackets	_Total	Total number of dropped network packets for the VM.
VMGuest-disk	freeMB	Disk partition name	The amount of free space (in MB) on this virtual disk.
VMGuest-disk	freePct	Disk partition name	The percentage of disk space available on this virtual disk.
VMGuest-memory	memoryActiveMB	_Total	Current amount of memory that is being 'actively used' by this virtual machine (in MB), as estimated by VMKernel based on recently touched memory pages.
VMGuest-memory	memoryActivePct	_Total	The current percentage of memoryActiveMB vs. memoryConsumedMB for this virtual machine.
VMGuest-memory	memoryBalloonPct	_Total	Amount of memory allocated to the virtual machine memory control driver (vmmemctl).
VMGuest-memory	memoryConsumedMB	_Total	The current maximum amount of memory assigned to this virtual machine (in MB). VMware refers to this as the 'memory consumed'.
VMGuest-memory	memoryLatencyPct	_Total	Percentage of time the VM is waiting to access swapped or compressed memory.
VMGuest-memory	memorySharedKB	_Total	The average amount of shared memory (in KB) for this virtual machine.
VMGuest-memory	memorySwapRateKB/s	_Total	The rate of KB swapped in or out per second for this VM during the interval.
VMGuest-memory	memoryUsedPct	_Total	Memory consumed as percentage of allocated memory for the VM.
VMGuest-disk	outstandingIOs	_Total	Average number of outstanding I/O requests to the virtual disk during the collection interval.
VMGuest-disk	outstandingIOs	Datastore name: Virtual disk name	Average number of outstanding I/O requests to the virtual disk during the collection interval.
VMGuest-disk	readLatency	Datastore name: Virtual disk name	Average amount of time that takes a read from the virtual disk.
VMGuest-net	receiveRateKB/s	_Total	Rate at which data is received across each vNIC instance on the VM.
VMGuest	snapshotAgeHours	_Total	The age of the oldest snapshot.
VMGuest	snapshotsSizeMB	_Total	Total size of snapshot files for the VM.
VMGuest-net	transmitRateKB/s	vNIC name	Rate at which data is transmitted across each vNIC instance on the VM.
VMGuest-net	usageRateKB/s	_Total	Rate at which data is sent and received across each vNIC instance on the VM.
VMGuest-disk	usageRateKB/s	Datastore name: Virtual disk name	Rate at which data is read and written to/from the virtual disk.
VMGuest-disk	usageRateKB/s	_Total	Rate at which data is read and written from/to the virtual disk for all disks of the virtual machine.
VMGuest-disk	usedStorageGB	_Total	Total storage space, in GB, committed to this virtual machine across all datastores.
VMGuest-disk	usedStorageGB	Datastore name	Storage space, in GB, committed to this virtual machine on this datastore.
VMGuest-disk	writeLatency	Datastore name: Virtual disk name	Average amount of time that takes a write to the virtual disk.

VM Template

VM Template
Object	Counter	Instance	Definition
VMGuest-disk	usedStorageGB	Datastore name	Total storage space, in GB, committed to this VM template across all datastores.
VMGuest-disk	usedStorageGB	_Total	Total storage space, in GB, committed to this VM template.
