Supported metrics for Microsoft.Network/expressRouteCircuits

The following table lists the metrics available for the Microsoft.Network/expressRouteCircuits resource type.

Table headings

  • Metric - The metric display name as it appears in the Azure portal.
  • Name in Rest API - Metric name as referred to in the REST API.
  • Advanced platform metrics - A premium, paid tier of platform metrics in Azure Monitor that provide more granular observability for Azure resources.
  • Unit - Unit of measure.
  • Aggregation - The default aggregation type. Valid values: Average, Minimum, Maximum, Total, Count.
  • Dimensions - Dimensions available for the metric.
  • Time Grains - Intervals at which the metric is sampled. For example, PT1M indicates that the metric is sampled every minute, PT30M every 30 minutes, PT1H every hour, and so on.
  • DS Export -S Whether the metric is exportable to Azure Monitor Logs via Diagnostic Settings.

For information on exporting metrics, see - Metrics export using data collection rules and Create diagnostic settings in Azure Monitor.

For information on metric retention, see Azure Monitor Metrics overview.
