Type Members

1.  case class AcceptableRange(lowerBoundInclusive: Double, upperBoundExclusive: Double) extends Bounds with Product with Serializable

   The state is considered healthy when the expression computation is inside this range.

   The state is considered healthy when the expression computation is inside this range. Health status and expression computation are not necessary linearly correlated.

2.  sealed trait Bounds extends AnyRef

   Thresholds are specified per-expression.

   Thresholds are specified per-expression. The default is Unbounded.

3.  case class ConstantExpression extends Expression with Product with Serializable

   Represents a constant double number

4.  case class ExpressionSchema extends Product with Serializable

   ExpressionSchema is builder class that construct an expression with its metadata.

5.  case class ExpressionSchemaKey(name: String, labels: Map[String, String], namespaces: Seq[String]) extends Product with Serializable

   ExpressionSchemaKey is a class that exists to serve as a key into a Map of ExpressionSchemas.

   ExpressionSchemaKey is a class that exists to serve as a key into a Map of ExpressionSchemas. It is simply a subset of the fields of the ExpressionSchema. Namely:

6.  case class FunctionExpression extends Expression with Product with Serializable

   Represents compound metrics and their arithmetical(or others) calculations

7.  case class HistogramExpression extends Expression with Product with Serializable

   Represent a histogram expression with specified component, for example the average, or a percentile

8.  case class MetricExpression extends Expression with Product with Serializable

   Represents the leaf metrics

9.  case class MonotoneThresholds(operator: Operator, badThreshold: Double, goodThreshold: Double, lowerBoundInclusive: Option[Double] = None, upperBoundExclusive: Option[Double] = None) extends Bounds with Product with Serializable

   Health status and expression computation are linearly correlated, and the healthier direction is indicated by operator.

   Health status and expression computation are linearly correlated, and the healthier direction is indicated by operator.

   [lowerBoundInclusive, badThreshold] bad [badThreshold, goodThreshold] ok [goodThreshold, upperBoundExclusive] good

   operator

   GreaterThan or LessThan

   lowerBoundInclusive

   Optional, undefined meaning unbounded lower bound.

   upperBoundExclusive

   Optional, undefined meaning unbounded upper bound.

   Note

   all ranges are lower inclusive and upper exclusive.

10.  sealed trait Operator extends AnyRef

    Represent Metric Expression thresholds operator.

11.  case class StringExpression extends Expression with Product with Serializable

    Represent an expression constructed from metrics in strings
