class MetricChangeFilter

Filter that compares a change in a metric value to a user-defined threshold. The change is calculated over “tumbling” windows, i.e. the difference between the current window and the non-overlapping prior window.

​
method MetricChangeFilter.__init__

__init__(
    name: 'str',
    agg: 'Agg | None' = None,
    window: 'int' = 1,
    cmp: 'None' = None,
    threshold: 'Annotated | Annotated',
    prior_window: 'int' = None,
    change_type: 'ChangeType',
    change_dir: 'ChangeDir'
) → None
Args:
  • name (str):
  • agg (Optional[Agg]):
  • window (int):
  • cmp (None): Ignored.
  • threshold (Union[Annotated, Annotated]):
  • prior_window (int): Size of the “prior” metric aggregation window (ignored if agg is None). If omitted, defaults to the size of the current window.
  • change_type (ChangeType):
  • change_dir (ChangeDir):
Returns: An MetricChangeFilter object.
