8.26.6 When a closing handshake request is received

The following figure shows the trace collection points in WebSocket.

Figure 8‒106: Trace collection points of WebSocket (when a closing handshake request is received (with payload data))

Figure 8‒107: Trace collection points of WebSocket (when a closing handshake request is received (no payload data))

The following table describes the event IDs, trace levels, trace collection points, and information that can be collected.
