## Overview

ONTAP CIFS sessions `show` functionality is used to provide a list of currently established CIFS sessions with SMB Clients.

### Information on the CIFS session

- List all the SMB sessions for SVM and the clients along with volume information on which the clients are using.

## Example

### Retrieves established sessions information

To retrieve the list of CIFS sessions, use the following API. Note that return_records=true.

    from netapp_ontap import HostConnection
    from netapp_ontap.resources import CifsSession

    with HostConnection(
        "<cluster-mgmt-ip>", username="admin", password="password", verify=False
    ):
        print(list(CifsSession.get_collection(return_timeout=15)))

Try it out

    [
        CifsSession(
            {
                "connection_count": 1,

## Classes

`class CifsSession (*args, **kwargs)`

  Allows interaction with CifsSession 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

  - Resource

  ### Static methods

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

    Retrieves the CIFS sessions information for all SVMs.

    ### Related ONTAP commands

    - `vserver cifs session show -active-volumes`

    ### Learn more

    - `DOC /protocols/cifs/sessions`

    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, body: typing.Union = None, connection: HostConnection = None, **kwargs) -> NetAppResponse`

    Deletes SMB session information on a node for an SVM. * To delete the specific SMB session information, pass the relavant SMB session's identifier and connection Id. * To delete all the SMB session information on specific connection, pass the specific SMB session's Identifier value as zero(0). * To delete all the SMB session information, pass the specific session's identifier and connection Id values as zero(0). * To delete all the SMB session information on specific Identifier alone is not allowed.

    ### Learn more

    - `DOC /protocols/cifs/sessions`

    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.
    `body`
      The body of the delete request. This could be a Resource instance or a dictionary object.
    `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 CIFS sessions information for all SVMs.

    ### Related ONTAP commands

    - `vserver cifs session show -active-volumes`

    ### Learn more

    - `DOC /protocols/cifs/sessions`

    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) -> typing.Iterable`

    Retrieves the CIFS sessions information for all SVMs.

    ### Related ONTAP commands

    - `vserver cifs session show -active-volumes`

    ### Learn more

    - `DOC /protocols/cifs/sessions`

    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.

  ### Methods

  `def delete(self, body: typing.Union = None, poll: bool = True, poll_interval: typing.Union = None, poll_timeout: typing.Union = None, **kwargs) -> NetAppResponse`

      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.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host.

    ## Returns

    A `NetAppResponse` object containing the details of the HTTP response.
