We are trying to determine the number of Azure App Service TCP Connections by Destination, to see exactly which piece code we need to look at see where port exhaustation might be occuring, is there a way to pull these logs rather then just get the summary view in the diagnose and solve problems view?

While I check on this internally with our product engineering team and get back. I understand you have already checked the diagnostic blade and reviewed the summary of the Connections. You have stated that "you're trying to determine the number of Azure App Service TCP Connections by Destination"- From the same diagnostic's blade > '
TCP connections'provides a snapshot of the maximum connections (IP:port)- Could you please just confirm, if you're referring to the same option or something else?

2020-10-30T21:32:42.827+00:00 @Sanil Lad , Just following-up to add these info as additional info:
Kindly review some of the App Service Sandbox limit
Cross VM Numerical Limits and Exhausting portsThis article is intended that provide resolutions for common problems can occur with outbound connections from an Azure Load Balancer. Most problems with outbound connectivity that customers experience are due to SNAT port exhaustion and connection timeouts leading to dropped packets. This article provides steps for mitigating each of these issues.
Thanks! I will follow-up on this shortly.

2020-11-02T11:45:49.68+00:00 @Sanil Lad , I'd checked on this with our product engineering team, As of today, we don’t have any plans to surface any other information apart from what the detector shows already (related to TCP Connections and SNAT Port Exhaustion -via Diagnose and solve problems). Apologies for any inconvenience with this.
