There does not seem to be a lot of information around how to use the AUDIT feature of the
AuthorizationPolicy object. Stackdriver is mentioned but there does not seem to be a way to run this without having a GKE account at the least or using a third-party vendor.
Is there any other way to have some tracing or trail of what connectivity is happening when using Authorization Policies?
I found this other dead thread but nothing really helpful on this board (and the invite link for the istio slack seems dead).
