CPU speed values

const CustomAttributeValNotSet string = "NotSet"

CustomAttributeValNotSet is used to indicate that a Custom Attribute value was not set on an object.

View Source 
const ParentResourcePool string = "Resources"

ParentResourcePool represents the hidden resource pool named Resources which is present on virtual machine hosts. This resource pool is a parent of all resource pools of the host. Including this pool in "eligible" resource pool lists throws off calculations (e.g., causes a VM to show up twice).

View Source 
const VMwareAdminAssistanceNeeded = "assistance needed from vmware administrators to resolve issue (see plugin doc for details)"

VMwareAdminAssistanceNeeded indicates that a known/detected problem can only be resolved with the assistance of the administrators of the VMware environment(s) monitored by plugins in this project. While this team may be the same ones to receive the notifications from the monitoring system using this project's plugin, that may not always be the case.

Variables

View Source 
var ErrAlarmNotExcludedFromEvaluation = errors.New("alarm detected and not excluded from evaluation")

ErrAlarmNotExcludedFromEvaluation indicates that one or more alarms were detected and not excluded from evaluation.

View Source 
var ErrAvailableFieldValueNotDefined = errors.New("no custom attributes defined within vSphere environment for this type")

ErrAvailableFieldValueNotDefined is returned when no Custom Attributes are defined within an inventory for an associated managed object type.

View Source 
var ErrAvailableFieldValueNotFound = errors.New("failed to find a matching available field name")

ErrAvailableFieldValueNotFound is returned when a specified Custom Attribute name cannot be located within an inventory. This might be the case if a specified Custom Attribute name has a typo.

View Source 
var ErrConvertBaseCustomFieldValue = errors.New("failed to convert base custom field value to obtain key/value pair")

ErrConvertBaseCustomFieldValue is returned when a conversion error occurs or (type assertion failure) for a provided BaseCustomFieldValue.

TODO: Document how/when this might occur.

View Source 
var ErrCustomAttributeKeyNotFound = errors.New("failed to find a matching custom attribute key/value pair for provided custom attribute key")

ErrCustomAttributeKeyNotFound is returned when a Custom Attribute key (and thus the desired value) cannot be found for a vSphere object. This can occur when a Custom Attribute exists within an inventory, but is not applied to a specific managed object.

View Source 
var ErrCustomAttributeNotSet = errors.New("custom attributes not set")

ErrCustomAttributeNotSet is similar to ErrCustomAttributeKeyNotFound, but is returned when there are no Custom Attributes set for an associated managed object type.

View Source 
var ErrDatacenterNotFound = errors.New("specified Datacenters not found")

ErrDatacenterNotFound indicates that one or more specified datacenters were not located.

View Source 
var ErrDatastoreInaccessible = errors.New("datastore is inaccessible")

View Source 
var ErrDatastoreIormConfigurationPropertyUnavailable = errors.New(
	"datastore storage I/O resource management configuration property unavailable",
)

ErrDatastoreIormConfigurationPropertyUnavailable indicates that the IORMConfigInfo property is not available for evaluation. Without this property, plugins in this project are unable to reliably determine whether datastore performance statistics are being gathered.

https://vdc-download.vmware.com/vmwb-repository/dcr-public/b50dcbbf-051d-4204-a3e7-e1b618c1e384/538cf2ec-b34f-4bae-a332-3820ef9e7773/vim.StorageResourceManager.IORMConfigInfo.html

View Source 
var ErrDatastoreIormConfigurationStatisticsCollectionDisabled = errors.New(

https://vdc-download.vmware.com/vmwb-repository/dcr-public/b50dcbbf-051d-4204-a3e7-e1b618c1e384/538cf2ec-b34f-4bae-a332-3820ef9e7773/vim.StorageResourceManager.IORMConfigInfo.html

View Source 
var ErrHostDatastorePairingFailed = errors.New("failed to compile host/datastore pairings")

ErrHostDatastorePairingFailed is returned when compiling host and datastore pairings using provided the Custom Attribute fails. This is usually due to a lack of a match between Custom Attribute values used on hosts and datastores.

For example, this may occur if prefix matching is not enabled and the host Custom Attribute uses a Location attribute which contains a separator between a datacenter and the hosts rack position, whereas a datastore contains only the datacenter.

View Source

View Source 
var ErrSnapshotCountThresholdCrossed = errors.New("snapshots exceed specified count threshold")

ErrSnapshotCountThresholdCrossed indicates that a snapshot set for a single VM has exceeded a specified count threshold.

View Source 
var ErrVirtualMachineBackupDateOld = errors.New(
	"virtual machine backup date exceeds specified threshold",
)

ErrVirtualMachineBackupDateOld indicates that a Virtual Machine has a backup date specified, but the backup is older than the user specified threshold.

View Source 
var ErrVirtualMachineConfigurationIsNil = errors.New("virtual machine configuration is nil")

ErrVirtualMachineConfigurationIsNil indicates that the configuration for a virtual machine is unset, which may occur if the property is not requested from the vSphere API or if the service account executing the plugin has insufficient privileges.

View Source 
var ErrVirtualMachineDiskConsolidationNeeded = errors.New("disk consolidation needed")

ErrVirtualMachineDiskConsolidationNeeded indicates that disk consolidation is needed for one or more Virtual Machines.

	// information) and then review further to determine whether the VM passes
	// specific criteria (e.g., backup within an expected window of time).
