Hi,

We want to know what the way is to get the Outbound Internet Traffic report and Graph to understand How much Internet bandwidth is utilized, we have a Firewall Appliance hosted in Azure through which we already exported the report, but we want to know the Outbound traffic from one particular Vnet to Internet.

We have enabled the Traffic Analytics but I'm looking for the KQL query which can give me this information Mbps/4 hrs. for last 7 days.

    Hi Arjun Vyavahare

    You can check outbound internet traffic using NSG flow logs.

    Refer: https://learn.microsoft.com/en-us/azure/network-watcher/traffic-analytics-usage-scenarios?source=recommendations#view-ports-and-virtual-machines-receiving-traffic-from-the-internet

    https://learn.microsoft.com/en-us/azure/network-watcher/vnet-flow-logs-overview

    Unfortunately, the KQL query is not possible to fetch the required data.

    If you wish you may upvote the feedback in the below forum requesting this feature. All the feedback you share in these forums will be monitored and reviewed by the Microsoft engineering teams responsible for building Azure.
