SSL debug and troubleshooting commands

Displaying proxy statistics
Use the show cp statistics command in the rconsole mode to display connection proxy statistics, as
shown in the following.
Syntax: show cp statistics
Displaying authentication statistics
Use the show ssl authentication-stats command in rconsole mode to display authentication
statistics about certificate verification on the ServerIron ADX. This information is relevant either in
the case of client certificate verification (on the client side), or while doing SSL proxy (on the server
side).
Syntax: show ssl authentication-stats
