Live Monitoring Billable Network Out for Current Day

StuFranks yea it is definitely possible, I believe you may be looking at the wrong place previously.

In Azure, you can actually leverage on https://docs.microsoft.com/en-us/azure/azure-monitor/overview, a solution that encompasses multiple monitoring services that allow you to monitor various services within Azure.

Since you are looking at identifying how much data has gone in and out from your VMs for the current day, https://docs.microsoft.com/en-us/azure/azure-monitor/vm/vminsights-overview might just fits in the picture. 

You can take a look at this https://azure.microsoft.com/en-us/blog/analysis-of-network-connection-data-with-azure-monitor-for-virtual-machines/ written by https://azure.microsoft.com/en-us/blog/author/sckingho/ , it provides a comprehensive guide on how to set it up in your environment, there are some configurations that need to be done.

One of the sample charts you can get from it is something like this

However, do take note that the network chart on the Azure VM Overview only displays network traffic that will be billed. It does not include inter-virtual network traffic.

Whereas the data and charts shown for VM insights is based on data from the guest VM and the network chart displays all TCP/IP traffic that is inbound and outbound to that VM, including inter-virtual network.

Lastly, there are actually tons of monitoring services available in Azure Monitor, depending on what are your requirements, you are bound to find something that you need in there.

Do let me know if it helps 😃
