Monitor Azure Route Server

  • Article

This article helps you understand Azure Route Server monitoring and metrics using Azure Monitor. Azure Monitor is one stop shop for all metrics, alerting and diagnostic logs across all of Azure.

Note

Using Classic Metrics is not recommended.

Prerequisites

View Route Server metrics

To view Azure Route Server metrics, follow these steps:

  1. Go to your Route Server resource in the Azure portal and select Metrics.

  2. Select a scalability metric. The default aggregation automatically applies.

Important

When viewing Route Server metrics in the Azure portal, select a time granularity of 5 minutes or greater for best possible results.

Aggregation types

Metrics explorer supports Sum, Count, Average, Minimum, and Maximum as aggregation types. 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.
Metric Category Unit Aggregation Type Description Dimensions Exportable via Diagnostic Settings?
BGP Peer Status Scalability Count Maximum BGP availability from Route Server to Peer BGP Peer IP, BGP Peer Type, Route Server Instance Yes
Count of Routes Advertised to Peer Scalability Count Maximum Count of routes advertised from Route Server to Peer BGP Peer IP, BGP Peer Type, Route Server Instance Yes
Count of Routes Learned from Peer Scalability Count Maximum Count of routes learned from Peer BGP Peer IP, BGP Peer Type, Route Server Instance Yes

Important

Azure Monitor exposes another metric for Route Server, Data Processed by the Virtual Hub Router. This metric doesn't apply to Route Server and should be ignored.

Route Server metrics

You can view the following metrics for Azure Route Server:

BGP Peer status

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.

To check the BGP status of a specific NVA peer, select Apply splitting and choose BgpPeerIp.

Count of routes advertised to peer

Aggregation type: Max

This metric shows the number of routes the Route Server advertised to NVA peers.
