Module netapp_ontap.resources.ntp_server

Copyright © 2022 NetApp Inc. All rights reserved.

Overview

You can use this API to add external NTP servers to a cluster, update the configuration, use NTP keys, and retrieve the current NTP server configuration.

Adding an NTP server to a cluster

To add an NTP server to a cluster, issue a POST /cluster/ntp/servers request.

Fields used for adding an NTP server

Except for the name of the NTP server (host name or IP address), which is specified by the server, all fields are optional:

  • version
  • key

If the key is provided in POST, authentication_enabled is set to true by default.

Examples

Adding an NTP server

from netapp_ontap import HostConnection
from netapp_ontap.resources import NtpServer

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = NtpServer()
    resource.server = "time.nist.gov"
    resource.post(hydrate=True)
    print(resource)


Adding an NTP server with an authentication key

from netapp_ontap import HostConnection
from netapp_ontap.resources import NtpServer

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = NtpServer()
    resource.server = "time.nist.gov"
    resource.key = {"id": 10}
    resource.post(hydrate=True)
    print(resource)


Enabling a previously configured shared key (ID, type, and value) for an NTP server

A combination of key number or identifier (ID), type of key, and shared key value is created with /api/cluster/ntp/keys. This operation will validate the NTP authentication works.

from netapp_ontap import HostConnection
from netapp_ontap.resources import NtpServer

with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
    resource = NtpServer(server="time.nist.gov")
    resource.key = {"id": 10}
    resource.authentication_enabled = True
    resource.patch()


Classes

class NtpServer (*args, **kwargs)

Allows interaction with NtpServer objects on the host

Initialize the instance of the resource.

Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

MyResource(name='foo').name == 'foo'

Args

*args
Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
**kwargs
each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

Ancestors

Static methods

def count_collection(*args, connection: HostConnection = None, **kwargs) -> int

Fetch a count of all objects of this type from the host.

This calls GET on the object to determine the number of records. It is more efficient than calling get_collection() because it will not construct any objects. Query parameters can be passed in as kwargs to determine a count of objects that match some filtered criteria.

Args

*args
Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the count of bars for a particular foo, the foo.name value should be passed.
connection
The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host. These query parameters can affect the count. A return_records query param will be ignored.

Returns

On success, returns an integer count of the objects of this type. On failure, returns -1.

Raises

NetAppRestError: If the API call returned a status code >= 400, or if there is no connection available to use either passed in or on the library.

def delete_collection(*args, records: Iterable[_ForwardRef('NtpServer')] = None, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

Deletes an external NTP server used by ONTAP.

Delete all objects in a collection which match the given query.

All records on the host which match the query will be deleted.

Args

*args
Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to delete the collection of bars for a particular foo, the foo.name value should be passed.
records
Can be provided in place of a query. If so, this list of objects will be deleted from the host.
body
The body of the delete request. This could be a Resource instance or a dictionary object.
poll
If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval
If the operation returns a job, this specifies how often to query the job for updates.
poll_timeout
If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.
connection
The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be deleted.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

NetAppRestError: If the API call returned a status code >= 400

def find(*args, connection: HostConnection = None, **kwargs) -> Resource

Retrieves the collection of external NTP time servers ONTAP uses for time adjustment and correction.

Find an instance of an object on the host given a query.

The host will be queried with the provided key/value pairs to find a matching resource. If 0 are found, None will be returned. If more than 1 is found, an error will be raised or returned. If there is exactly 1 matching record, then it will be returned.

Args

*args
Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to find a bar for a particular foo, the foo.name value should be passed.
connection
The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs
Any key/value pairs passed will be sent as query parameters to the host.

Returns

A Resource object containing the details of the object or None if no matches were found.

Raises

NetAppRestError: If the API call returned more than 1 matching resource.

def get_collection(*args, connection: HostConnection = None, max_records: int = None, **kwargs) -> Iterable[Resource]

Retrieves the collection of external NTP time servers ONTAP uses for time adjustment and correction.

  • cluster time-service ntp server show

Fetch a list of all objects of this type from the host.

This is a lazy fetch, making API calls only as necessary when the result of this call is iterated over. For instance, if max_records is set to 5, then iterating over the collection causes an API call to be sent to the server once for every 5 records. If the client stops iterating before getting to the 6th record, then no additional API calls are made.

Args

*args
Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the collection of bars for a particular foo, the foo.name value should be passed.
connection
The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
max_records
The maximum number of records to return per call
**kwargs
Any key/value pairs passed will be sent as query parameters to the host.

Returns

A list of Resource objects

Raises

NetAppRestError: If there is no connection available to use either passed in or on the library. This would be not be raised when get_collection() is called, but rather when the result is iterated.
