name	Name of the criteria.	string (required)
skipMetricValidation	Allows creating an alert rule on a custom metric that isn't yet emitted, by causing the metric validation to be skipped.	bool
timeAggregation	the criteria time aggregation types.	"Average" "Count" "Maximum" "Minimum" "Total" (required)
criterionType	Set the object type	DynamicThresholdCriterion StaticThresholdCriterion (required)

MetricDimension

Name	Description	Value
name	Name of the dimension.	string (required)
operator	the dimension operator. Only 'Include' and 'Exclude' are supported	string (required)
values	list of dimension values.	string[] (required)

DynamicMetricCriteria

Name	Description	Value
criterionType	Specifies the type of threshold criteria	"DynamicThresholdCriterion" (required)
alertSensitivity	The extent of deviation required to trigger an alert. This will affect how tight the threshold is to the metric series pattern.	"High" "Low" "Medium" (required)
failingPeriods	The minimum number of violations required within the selected lookback time window required to raise an alert.	DynamicThresholdFailingPeriods (required)
ignoreDataBefore	Use this option to set the date from which to start learning the metric historical data and calculate the dynamic thresholds (in ISO8601 format)	string
operator	The operator used to compare the metric value against the threshold.	"GreaterOrLessThan" "GreaterThan" "LessThan" (required)

DynamicThresholdFailingPeriods

Name	Description	Value
minFailingPeriodsToAlert	The number of violations to trigger an alert. Should be smaller or equal to numberOfEvaluationPeriods.	int (required)
numberOfEvaluationPeriods	The number of aggregated lookback points. The lookback time window is calculated based on the aggregation granularity (windowSize) and the selected number of aggregated points.	int (required)

MetricCriteria

Name	Description	Value
criterionType	Specifies the type of threshold criteria	"DynamicThresholdCriterion" "StaticThresholdCriterion" (required)
dimensions	List of dimension conditions.	MetricDimension[]
metricName	Name of the metric.	string (required)
metricNamespace	Namespace of the metric.	string
name	Name of the criteria.	string (required)
operator	the criteria operator.	"Equals" "GreaterThan" "GreaterThanOrEqual" "LessThan" "LessThanOrEqual" (required)
skipMetricValidation	Allows creating an alert rule on a custom metric that isn't yet emitted, by causing the metric validation to be skipped.	bool
threshold	the criteria threshold value that activates the alert.	int (required)
timeAggregation	the criteria time aggregation types.	"Average" "Count" "Maximum" "Minimum" "Total" (required)

MetricAlertSingleResourceMultipleMetricCriteria

Name	Description	Value
odata.type	specifies the type of the alert criteria.	"Microsoft.Azure.Monitor.SingleResourceMultipleMetricCriteria" (required)
allOf	The list of metric criteria for this 'all of' operation.	MetricCriteria[]
