VMDatastore
|
deviceReadLatency
|
Host name:disk
name
|
The average amount
of time taken to complete a read from the physical device. This is
the time from the device to the host HBA (in milliseconds).
|
VMDatastore
|
deviceWriteLatency
|
Host name:disk
name
|
The average amount
of time taken to complete a write to the physical device. This is
the time from the host HBA to the device (in milliseconds).
|
VMDatastore
|
diskPressure
|
_Total
|
The ratio of
allocated storage to storage capacity, expressed as a percentage.
This percentage can be greater than 100 if thin-provisioning
(storage overcommit) is used extensively. See related metric
ProvisionedGB.
|
VMDatastore
|
freeGB
|
_Total
|
Amount of
datastore space that is not currently used.
|
VMDatastore
|
IOPS
|
Host name
|
Aggregate number
of I/O operations on the datastore per host.
|
VMDatastore
|
IOPS
|
_Total
|
Number of
input/output operations per second, calculated as total of (reads +
writes) divided by the collection interval.
|
VMDatastore
|
IOPS
|
Host name:disk
name
|
Aggregate number
of I/O operations on the datastore per second.
|
VMDatastore
|
MaxDeviceLatency
|
_Total
|
Highest physical
device latency value on the datastore during the collection
interval.
|
VMDatastore
|
MaxDeviceReadLatency
|
_Total
|
Highest physical
device latency value on the datastore (in milliseconds) for read
operations.
|
VMDatastore
|
MaxDeviceWriteLatency
|
_Total
|
Highest physical
device latency value on the datastore (in milliseconds) for write
operations.
|
VMDatastore
|
ProvisionedGB
|
_Total
|
Amount of space in
GB that is provisioned (allocated) on the datastore. This can
exceed the actual capacity of the datastore if thin-provisioning is
used extensively (storage overcommit).
|
VMDatastore
|
readRateKB/s
|
_Total
|
Average read rate
per second for the datastore (in KB).
|
VMDatastore
|
unknownFilesGB
|
_Total
|
Amount of storage
space (in GB) occupied by files unknown to vCenter (orphaned
snapshots, orphaned VMs, or manually uploaded files such as ISO,
etc.) on the datastore.
|
VMDatastore
|
usedPct
|
_Total
|
Percentage of
space in use on the VMFS. That is, diskUse vs. diskSize.
|
VMDatastore
|
VMObservedLatency
|
_Total
|
The average
datastore latency as seen by virtual machines.
|
VMDatastore
|
vmTotal
|
_Total
|
Number of VMs
whose disks reside on the datastore. This number includes both
virtual machines and VM templates.
|
VMDatastore
|
writeRateKB/s
|
_Total
|
Average write rate
per second for the datastore (in KB).
