* It is possible to check each pod protocol in the information tooltip. In Ambient, instead of TCP, it uses HBONE.

* When workload traffic is handled by a Waypoint, the workload details will show a link to the proxy:

### Waypoint proxy details

The workload details for a Waypoint has specific Waypoint data. It is identified with the L7 label:

![Waypoint label](/images/documentation/features/ambient/waypoint-label.png)

The proxy status shows a new info message when some of the Discovery Services are IGNORED, and there are no other errors:

![Waypoint proxy status](/images/documentation/features/ambient/waypoint-proxy-status.png)

This condition is usually expected, but it is shown as an info in case it is not.

The waypoint proxy generates traces for the services for which it handles traffic, and this is where it can be checked, because the proxy generates the traces with the waypoint service name:

For waypoint proxies, it is also possible to see the Envoy tab:

### ztunnel details

The workload details for a Ztunnel workload has specific data. It has a new Ztunnel tab containing the configuration for the services and workloads for which it handles traffic.
It shows the same information that can be seen using the `istioctl ztunnel-config`, which can be useful for troubleshooting.

### Ambient Telemetry

The Traffic graph generated with Ambient telemetry differs slightly from the usual graph, as the HTTP traffic and TCP traffic have different reporters.
