Network Watcher - Traffic Analytics (Outbound Traffic)

Question

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

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