__init__(self, resource_root, hostId=None, hostname=None, ipAddress=None, rackId=None)
(Constructor)

source code 

Initializes internal state and sets all known writable properties of the object to None. Then initializes the properties given in the provided attributes dictionary.

Parameters:
  • resource_root - API resource object.
  • attrs - optional dictionary of attributes to set. This should only contain r/w attributes.
Overrides: object.__init__
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 

Default implementation of __str__. Uses the type name and the first attribute retrieved from the attribute map to create the string.

Overrides: object.__str__
(inherited documentation)

_path(self)

source code 

Returns the path to the resource.

e.g., for a service 'foo' in cluster 'bar', this should return '/clusters/bar/services/foo'.

Overrides: types.BaseApiResource._path
(inherited documentation)

_put(self)

source code 

Update this resource.

Returns:
The updated object.
Overrides: types.BaseApiResource._put

get_config(self, view=None)

source code 

Retrieve the host's configuration.

The 'summary' view contains strings as the dictionary values. The full view contains ApiConfig instances as the values.

Parameters:
  • view - View to materialize ('full' or 'summary')
Returns:
Dictionary with configuration data.

update_config(self, config)

source code 

Update the host's configuration.

Parameters:
  • config - Dictionary with configuration to update.
Returns:
Dictionary with updated configuration.

get_metrics(self, from_time=None, to_time=None, metrics=None, ifs=[], storageIds=[], view=None)

source code 

This endpoint is not supported as of v6. Use the timeseries API instead. To get all metrics for a host with the timeseries API use the query:

'select * where hostId = $HOST_ID'.

To get specific metrics for a host use a comma-separated list of the metric names as follows:

'select $METRIC_NAME1, $METRIC_NAME2 where hostId = $HOST_ID'.

For more information see http://tiny.cloudera.com/tsquery_doc

Parameters:
  • from_time - A datetime; start of the period to query (optional).
  • to_time - A datetime; end of the period to query (default = now).
  • metrics - List of metrics to query (default = all).
  • ifs - network interfaces to query. Default all, use None to disable.
  • storageIds - storage IDs to query. Default all, use None to disable.
  • view - View to materialize ('full' or 'summary')
Returns:
List of metrics and their readings.

enter_maintenance_mode(self)

source code 

Put the host in maintenance mode.

Returns:
Reference to the completed command.

Since: API v2

exit_maintenance_mode(self)

source code 

Take the host out of maintenance mode.

Returns:
Reference to the completed command.

Since: API v2
