feat(alarm): add MathExpression support for minSampleCountToEvaluateDatapoint #466

Closed ketsugi closed 7 months ago

ketsugi commented 7 months ago

As discussed outside of Github, this PR adds MathExpression support for minSampleCountToEvaluateDatapoint under the following circumstances:

  1. If the MathExpression only has a single metric, convert to a sampleCount metric and use it for the minSampleCount
  2. If there are more than one metric, rely on the new optional sampleCountMetricId prop to determine which existing metric in the MathExpression should be used for the sampleCount
  3. Otherwise, throw an Error
