virtual network peering monitor

Hi ,

There is a requirement to monitor the traffic throughput on vnet peering . Is there any traffic monitor option to check on vent peering?

    If you're interested in monitoring RoundTripTimeMs between VNETs over a peer connection, you could setup Connection Monitors from Network Watcher. This will track the data in a log analytics workspace and allow you to view latency over time as well as alert on failures. I'm not aware of anything in Monitor or ability to monitor the peer connection itself.

    @prabhudoss jayakumar Thank you for reaching out to Microsoft Q&A. I understand that you want to know if there is a tool that can help with Bandwidth monitoring between VMs connected via Peering, is that right?

    You can always use the NTTTCP Tool for the same which is recommended by Azure. Please find details here for using this tool-

    You can also use Iperf for Bandwidth Monitoring. Please find details here-
    Download Iperf here-

    Please note:

    The network latency between virtual machines in peered virtual networks in the same region is the same as the latency within a single virtual network. The network throughput is based on the bandwidth that's allowed for the virtual machine, proportionate to its size. There isn't any additional restriction on bandwidth within the peering.
    The traffic between virtual machines in peered virtual networks is routed directly through the Microsoft backbone infrastructure, not through a gateway or over the public Internet.

    Therefore, factors such as the actual size of the VMs, regional latency between the VMs may affect the Bandwidth that you can achieve between the VMs. Hope this helps.

    Please let us know if you have any further questions and we will be glad to assist you further. Thank you!

    Thank you for sharing ..It helps. Let's say my customer has hybrid architecture with EXPRESSROUTE gateway and hub and spoke architecture. Hub vnet peered with multiple spoke vnet. Can i monitor real time traffic flowing through vnet peering between one hub vnet to spoke vnet?
