Monitor websocket ping/pong

[optimry]

Hi Guys

I have a websocket server and would like to monitor the pings from the clients and perhaps also the pongs from the server.

I handle messages using UseWebSocketMessageHandler and sessions using UseSessionHandler.
How do I know when a ping is beeing received from a client?
I did not write the code for the clients and would like to monitor the pings for diagnostics purposes and maybe add the info to a logfile.

Regards
Martin
