__init__(*, color=None, label=None, period=None, expression, using_metrics)

Properties for a MathExpression.

Parameters

  • color (Optional[str]) – Color for this metric when added to a Graph in a Dashboard. Default: - Automatic color

  • label (Optional[str]) – Label for this metric when added to a Graph in a Dashboard. Default: - Expression value is used as label

  • period (Optional[Duration]) – The period over which the expression’s statistics are applied. This period overrides all periods in the metrics used in this math expression. Default: Duration.minutes(5)

  • expression (str) – The expression defining the metric.

  • using_metrics (Mapping[str, IMetric]) – The metrics used in the expression, in a map. The key is the identifier that represents the given metric in the expression, and the value is the actual Metric object.
