    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
