msticpy.data.drivers.kusto_driver module

Kusto Driver subclass.

class msticpy.data.drivers.kusto_driver.KustoDriver(connection_str: str | None = None, **kwargs)

Bases: KqlDriver

Kusto Driver class to execute kql queries for Azure Data Explorer.

Instantiate KustoDriver.

Parameters:

  • connection_str (str, optional) – Connection string

  • debug (bool) – print out additional diagnostic information.

add_query_filter(name: str, query_filter: str | Iterable)

Add an expression to the query attach filter.

connect(connection_str: str | None = None, **kwargs)

Connect to data source.

Parameters:

  • connection_str (str) – Connect to a data source

  • cluster (str, optional) – Short name or URI of cluster to connect to.

  • database (str, optional) – Name of database to connect to.

  • kqlmagic_args (str, optional) – Additional string of parameters to be passed to KqlMagic

  • mp_az_auth (Union[bool, str, list, None], optional) – Optional parameter directing KqlMagic to use MSTICPy Azure authentication. Values can be: True or “default”: use the settings in msticpyconfig.yaml ‘Azure’ section str: single auth method name (‘msi’, ‘cli’, ‘env’, ‘vscode’, ‘powershell’, ‘cache’ or ‘interactive’) List[str]: list of acceptable auth methods from (‘msi’, ‘cli’, ‘env’, ‘vscode’, ‘powershell’, ‘cache’ or ‘interactive’)

  • mp_az_tenant_id (str, optional) – Optional parameter specifying a Tenant ID for use by MSTICPy Azure authentication.

property connected: bool

Return true if at least one connection has been made.

Returns:

True if a successful connection has been made.

Return type:

bool

Notes

This does not guarantee that the last data source connection was successful. It is a best effort to track whether the provider has made at least one successful authentication.

property driver_queries: Iterable[Dict[str, Any]]

Return queries retrieved from the service after connecting.

Returns:

List of Dictionary of query_name, query_text. Name of container to add queries to.

Return type:

List[Dict[str, str]]

get_driver_property(name: str) → Any

Return value or KeyError from driver properties.

static get_http_timeout(**kwargs)

Get http timeout from settings or kwargs.

property instance: str | None

Return instance name, if one is set.

Returns:

The name of driver instance or None if the driver does not support multiple instances

Return type:

Optional[str]

property loaded: bool

Return true if the provider is loaded.

Returns:

True if the provider is loaded.

Return type:

bool

Notes

This is not relevant for some providers.

query(query: str, query_source: QuerySource | None = None, **kwargs) → DataFrame | Any

Execute query string and return DataFrame of results.

Parameters:

  • query (str) – The query to execute

  • query_source (QuerySource) – The query definition object

  • cluster (str, Optional) – Supply or override the Kusto cluster name

  • database (str, Optional) – Supply or override the Kusto database name

  • data_source (str, Optional) – alias for db

  • connection_str (str, Optional)

Returns:

A DataFrame (if successful) or the underlying provider result if an error.

Return type:

Union[pd.DataFrame, results.ResultSet]

property query_attach_spec: Dict[str, Set[str]]

Parameters that determine whether a query is relevant for the driver.

query_usable(query_source: QuerySource) → bool

Return True if query should be exposed for this driver.

query_with_results(query: str, **kwargs) → Tuple[DataFrame, Kqlmagic.kql_proxy.KqlResponse]

Execute query string and return DataFrame of results.

Parameters:

query (str) – The kql query to execute

Returns:

A DataFrame (if successful) and Kql ResultSet.

Return type:

Tuple[pd.DataFrame, results.ResultSet]

property schema: Dict[str, Dict]

Return current data schema of connection.

Returns:

Data schema of current connection.

Return type:

Dict[str, Dict]

property service_queries: Tuple[Dict[str, str], str]

Return queries retrieved from the service after connecting.

Returns:

Dictionary of query_name, query_text. Name of container to add queries to.

Return type:

Tuple[Dict[str, str], str]

set_driver_property(name: str, value: Any)

Set an item in driver properties.
