Cannot create custom metric alert via azure cli.

Note: this pertains to https://docs.microsoft.com/en-us/cli/azure/monitor/metrics?view=azure-cli-latest#az-monitor-metrics-list-definitions and https://docs.microsoft.com/en-us/cli/azure/monitor/metrics/alert?view=azure-cli-latest#az-monitor-metrics-alert-create

Describe the bug I ran

$aiid = "/subscriptions/CENSORED/resourceGroups/CENSORED/providers/microsoft.insights/components/CENSORED"
az monitor metrics list-definitions --resource $aiid

and expected to see my custom metric definitions (in custom namespaces), but didn’t found any custom metrics.

To Reproduce Log a custom metric from the source code using ApplicationIsnights. Observe you can create an alert using it it via azure portal, or view it in metrics view in AI. However, it is not listed via list-definitions, nor you can create an alert via Azure CLI using it, as it is not found.

Expected behavior The custom metric (and its namespace) to be listed, and accepted when creating an alert with az monitor metrics alert create.

Environment summary

az --version
azure-cli                         2.0.66

Additional context Confirmed the custom metrics also cannot be found via

Get-AzMetricDefinition -ResourceId $aiid

If you pass an empty string to -DynamicThreshold it lets you create the criteria unfortunatelly when you create the alert rule it comes with static “default” threshold.

protected override void ProcessRecordInternal() |  
-- | --
  | {
  | if(String.IsNullOrWhiteSpace(this.DynamicThreshold))
  | {
  | List<MetricDimension> metricDimensions = new List<MetricDimension>();
  |  
  | if (this.DimensionSelection!= null && this.DimensionSelection.Length > 0)
  | {
  | foreach (var dimension in this.DimensionSelection)
  | {
  | if (dimension.IncludeValues != null && dimension.IncludeValues.Count() > 0)
  | {
  | metricDimensions.Add(new MetricDimension(dimension.Dimension, "Include", dimension.IncludeValues));
  | }
  | if (dimension.ExcludeValues != null && dimension.ExcludeValues.Count() > 0)
  | {
  | metricDimensions.Add(new MetricDimension(dimension.Dimension, "Exclude", dimension.ExcludeValues));
  | }
  | }
  | }
  | else
  | {
  | metricDimensions = null;
  | }
  | MetricCriteria metricCriteria = new MetricCriteria(name: "metric1", metricName: this.MetricName, operatorProperty: this.Operator, timeAggregation: this.TimeAggregation, threshold: this.Threshold, metricNamespace: this.MetricNamespace, dimensions: metricDimensions);
  | PSMetricCriteria result = new PSMetricCriteria(metricCriteria);
  | WriteObject(sendToPipeline: result);
  | }
  | else
  | {
  | WriteExceptionError(new Exception("Creating   criteria for Dynamic Threshold is not yet supported"));
  | }
