Network trace or Packet capture without VM

New Contributor

Hi, trying to debug tcp timeout problems, On-Premises server calls Azure App Service via Private endpoint.

Site-to-site is ExpressRoute, calls from on-prem occasionally ends up in timeout. These failed calls are seen in App Service logs however, and are answered correctly according to our software developer team.

So I would like to capture packets in Azure between ER GW and App service Private Endpoint (app, linux, container) but don't know how? For example NSG Flow Logs don't capture anything. How to accomplish this?

 

BR, Mika
