Diagnostic setting private connectivity

Question

When we setup diagnostic settings to send logs to a log analytics workspace, there doesn't seem to be an option for connecting the setting to a virtual network. Is the logging information gathered privately in Azure?

Hello @Grafton, Darren

Diagnostics are not routed through a public network. Our documentation on Azure Monitor Private Link scope states the following:

Logs and metrics uploaded to a workspace via Diagnostic Settings go over a secure private Microsoft channel and are not controlled by these settings.

I hope this helps provide you with the information you need. If it does, please make sure to mark the question as answered so it helps other people in future.

Hello @Grafton, Darren ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand that you would like to know if the diagnostic settings to send logs to a log analytics workspace happens privately in Azure.

Logs and metrics uploaded to a workspace via Diagnostic Settings go over a secure private Microsoft channel.
Refer : https://learn.microsoft.com/en-us/azure/azure-monitor/logs/private-link-design#exceptions

However, if you would like to connect privately to Azure Monitor ensuring that your monitoring data is only accessed through authorized private networks, then you could setup Azure Private Link to connect networks to Azure Monitor.
Refer : https://learn.microsoft.com/en-us/azure/azure-monitor/logs/private-link-security
