Azure - Get Current Status of the Load Balancer Probe

Question

We have a load balanced set in Azure for our web application, which load balances port 80 and 443 between two VMs. We have used the default tcp probe. Is there a way to get the current status of the probe for the load balancer from Azure?

I know I could just check each individual machines and do a probe myself, but I want to know if we could see what Azure sees for each machine.

Well as of 2018-06-05 this feature is not available in the Azure Portal. Today you have to configure "Diagnostic Logs" for the Load Balancer. If you choose the "Storage Account" option a JSON file is created with records like below

        {
         "time": "2018-06-05T08:50:04.2266987Z",
         "systemId": "XXXXXXXX-XXXX-XXXX-XXXX-d81b04ac33df",
         "category": "LoadBalancerProbeHealthStatus",
         "resourceId": "/SUBSCRIPTIONS/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX/RESOURCEGROUPS/TEST-INT/PROVIDERS/MICROSOFT.NETWORK/LOADBALANCERS/TEST-LB",
         "operationName": "LoadBalancerProbeHealthStatus",
         "properties": {"publicIpAddress":"XXX.XXX.XXX.XXX","port":8080,"totalDipCount":2,"dipDownCount":0,"healthPercentage":100.000000}
    }
    ,
    {
         "time": "2018-06-05T08:50:09.2415410Z",
         "systemId": "XXXXXXXX-XXXX-XXXX-XXXX-d81b04ac33df",
         "category": "LoadBalancerProbeHealthStatus",
         "resourceId": "/SUBSCRIPTIONS/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX/RESOURCEGROUPS/TEST-INT/PROVIDERS/MICROSOFT.NETWORK/LOADBALANCERS/TEST-LB",
         "operationName": "LoadBalancerProbeHealthStatus",
         "properties": {"publicIpAddress":"XXX.XXX.XXX.XXX","port":8080,"totalDipCount":2,"dipDownCount":1,"healthPercentage":50.000000}
    }

"Log Analytics" suggested by Eric is not mandatory but can be used to analyze these LB logs.
