This read-only gauge reports how many users are currently authenticated via the HTTP method on the Clavister firewall's user authentication feature. It gives an admin real-time visibility into how many sessions are using unencrypted HTTP-based authentication specifically, as opposed to the other auth methods tracked by sibling counters. For example, a persistently high clvUserAuthHTTPUsers count might prompt an admin to push users toward the HTTPS-based method for stronger security.
