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's 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, then the cpuUsedPct would be 90% (since 6,000 is the maximum that a 2-core VM could consume).

Correspondly, 5.400 MHz represents 23% of the vSphere host's total capability of 24,000 Mhz. Refer to 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 would 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.
