-## Route Server metrics
+## Prerequisites
+
+- An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/free/?WT.mc_id=A261C142F).
+- An Azure Route Server. If you need to create a Route Server, see [Create and configure Azure Route Server](quickstart-configure-route-server-portal.md).

+## View Route Server metrics
+
+To view Azure Route Server metrics, follow these steps:
 
-To view Azure Route Server metrics, go to your Route Server resource in the Azure portal and select **Metrics**.
+1. Go to your Route Server resource in the Azure portal and select **Metrics**.
 
-Once a metric is selected, the default aggregation is applied. Optionally, you can apply splitting, which shows the metric with different dimensions.
+1. Select a scalability metric. The default aggregation automatically applies.

+## Aggregation types
 
-Metrics explorer supports Sum, Count, Average, Minimum and Maximum as [aggregation types](../azure-monitor/essentials/metrics-charts.md#aggregation). You should use the recommended Aggregation type when reviewing the insights for each Route Server metric.
-
-* Sum: The sum of all values captured during the aggregation interval.
-* Count: The number of measurements captured during the aggregation interval.
-* Average: The average of the metric values captured during the aggregation interval.
-* Minimum: The smallest value captured during the aggregation interval.
-* Maximum: The largest value captured during the aggregation interval.

 Aggregation type: **Max**
 
 This metric shows the BGP availability of peer NVA connections. The BGP Peer Status is a binary metric. 1 = BGP is up-and-running. 0 = BGP is unavailable.
