Generally Available: Azure Load Balancer bandwidth metrics now support Protocol dimension
Bandwidth metrics for Azure Load Balancer are now published with metric dimension Protocol. When retrieving or viewing Byte, Packet, and SYN Count metrics in the Azure portal, you will now see the dimension Protocol. TCP traffic is denoted by Protocol=6, while UDP traffic is represented by Protocol=17.
With the Protocol dimension, you gain more granular visibility into traffic patterns for alerting, monitoring, and troubleshooting requirements.
The Protocol dimension is available on Byte, Packet, and SYN Count metrics in all Azure public regions, China cloud regions, and Government cloud regions.
