class VmReactionOnAPDCleared(string)

Bases: vmware.vapi.bindings.enum.Enum

If an APD condition clears after an APD timeout condition has been declared and before VM Component Protection service terminated the VM, the guestOS and application may no longer be operational.

Note

This class represents an enumerated type in the interface language definition. The class contains class attributes which represent the values in the current version of the enumerated type. Newer versions of the enumerated type may contain new values. To use new values of the enumerated type in communication with a server that supports the newer version of the API, you instantiate this class. See enumerated type description page.

Parameters

string (str) – String value for the VmReactionOnAPDCleared instance.

NONE = VmReactionOnAPDCleared(string='NONE')

VM Component Protection service will not react after APD condition is cleared.

RESET = VmReactionOnAPDCleared(string='RESET')

VM Component Protection service will reset the VM after APD condition is cleared. Note this only applies if the subject VM is still powered on.

USE_CLUSTER_DEFAULT = VmReactionOnAPDCleared(string='USE_CLUSTER_DEFAULT')

VM will use the cluster default setting. This option is only meaningful for per-VM settings.

Tip

The arguments are used to initialize data attributes with the same names.

Parameters

  • name (str) – Reference to the virtual machine.

  • vm_restart_priority (FailuresAndResponses.RestartPriority or None) – Restart priority for a virtual machine. If None or empty, the value is skipped.

  • vm_additional_delay (long or None) – After condition has been met, a mandatory delay before starting the next VM restart priority.

  • vm_restart_priority_timeout (long or None) – This setting is used to specify a maximum time the lower priority VMs should wait for the higher priority VMs to be ready. If the higher priority Vms are not ready by this time, then the lower priority VMs are restarted irrespective of the VM ready state. This timeout can be used to prevent the failover of lower priority VMs to be stuck infinitely. If None or empty, the value is skipped.

  • vm_isolation_response (FailuresAndResponses.IsolationResponse or None) –

    Indicates whether or not the virtual machine should be powered off if a host determines that it is isolated from the rest of the compute resource.

    If not specified at either the cluster level or the virtual machine level, this will default to powerOff. If None or empty, the value is skipped.

  • vm_datastore_with_pdl_failure_response (FailuresAndResponses.StorageVmReaction) – VM storage protection setting for storage failures categorized as Permenant Device Loss (PDL). PDL indicates storage device failure or LUN removal. In case of PDL, the failed datastore or device is unlikely to recover. The details of PDL are

  • vm_apd_failure_response (FailuresAndResponses.StorageVmReaction) – VM storage protection setting for storage failures categorized as All Paths Down (APD). APD is a condition where a storage has become inaccessible for unknown reasons. It only indicates loss of connectivity and does not indicate storage device failure or LUN removal (Permanent Device Loss or PDL)

  • vm_apd_failover_delay (long or None) – The time interval after an APD timeout has been declared and before VM Component Protection service will terminate the VM. The default value is 180 seconds if not specified. To use cluster setting for a VM override, set to -1 in per-VM setting.

  • vm_apd_response_recovery (FailuresAndResponses.VmReactionOnAPDCleared or None) – Action taken by VM Component Protection service for a powered on VM when APD condition clears after APD timeout. This property is meaningful only when vSphere HA is turned on. Valid values are

  • vm_monitoring (FailuresAndResponses.VmMonitoringState or None) – Virtual machine health monitoring is disabled. In this state, HA response to guest and application heartbeat failures are disabled.

Parameters
class HBDatastoreCandidate(string)

Bases: vmware.vapi.bindings.enum.Enum

The policy to determine the candidates from which vCenter Server can choose heartbeat datastores.

Note

This class represents an enumerated type in the interface language definition. The class contains class attributes which represent the values in the current version of the enumerated type. Newer versions of the enumerated type may contain new values. To use new values of the enumerated type in communication with a server that supports the newer version of the API, you instantiate this class. See enumerated type description page.

Parameters

string (str) – String value for the HBDatastoreCandidate instance.

ALL_FEASIBLE_DS = HBDatastoreCandidate(string='ALL_FEASIBLE_DS')

vCenter Server chooses heartbeat datastores from all the feasible ones, i.e., the datastores that are accessible to more than one host in the cluster. The choice will be made without giving preference to those specified by the user (see #heartbeatDatastore).

ALL_FEASIBLE_DS_WITH_USER_PREFERENCE = HBDatastoreCandidate(string='ALL_FEASIBLE_DS_WITH_USER_PREFERENCE')

vCenter Server chooses heartbeat datastores from all the feasible ones while giving preference to those specified by the user (see #heartbeatDatastore). More specifically, the datastores not included in #heartbeatDatastore will be chosen if and only if the specified ones are not sufficient.

USER_SELECTED_DS = HBDatastoreCandidate(string='USER_SELECTED_DS')

vCenter Server chooses heartbeat datastores from the set specified by the user (see #heartbeatDatastore). More specifically, datastores not included in the set will not be chosen. Note that if #heartbeatDatastore is empty, datastore heartbeating will be disabled for HA.

class com.vmware.appliance.vcenter.settings.v1.config.components.inventory.cluster.ha_client.VmToolsMonitoringSettings(enabled=None, cluster_settings=None, failure_interval=None, min_up_time=None, max_failures=None, max_failure_window=None)

Bases: vmware.vapi.bindings.struct.VapiStruct

The vim.cluster.VmToolsMonitoringSettings data object contains virtual machine monitoring settings that are used by the Virtual Machine Health Monitoring Service. The Service checks the VMware Tools heartbeat of a virtual machine. If heartbeats have not been received within a specified time interval, the Service declares the virtual machine as failed and resets the virtual machine. All fields are optional. In case of a reconfiguration, fields left unset are not changed.

Tip

The arguments are used to initialize data attributes with the same names.

Parameters

  • enabled (bool or None) –

    Flag indicating whether or not the Virtual Machine Health Monitoring service is enabled.

    The Server does not use this property.

  • cluster_settings (bool or None) –

    Flag indicating whether to use the cluster settings or the per VM settings.

    The default value is true.

  • failure_interval (long or None) –

    If no heartbeat has been received for at least the specified number of seconds, the virtual machine is declared as failed.

    The default value is 30.

  • min_up_time (long or None) –

    The number of seconds for the virtual machine’s heartbeats to stabilize after the virtual machine has been powered on. This time should include the guest operating system boot-up time. The virtual machine monitoring will begin only after this period.

    The default value is 120.

  • max_failures (long or None) –

    Maximum number of failures and automated resets allowed during the time that VmToolsMonitoringSettings.max_failure_window specifies. If VmToolsMonitoringSettings.max_failure_window is -1 (no window), this represents the absolute number of failures after which automated response is stopped.

    If a virtual machine exceeds this threshold, in-depth problem analysis is usually needed.

    The default value is 3.

  • max_failure_window (long or None) –

    The number of seconds for the window during which up to VmToolsMonitoringSettings.max_failures resets can occur before automated responses stop.

    If set to -1, no failure window is specified.

    The default value is -1.
