@okhowang , a lot of information about the props of the TLS conn may be fetched via variables, see https://opensips.org/html/docs/modules/3.4.x/tls_mgm.html#idp5733984.
Typically the statistics are counters / numerical values, so not suitable for what you described here.
Let me know if there is anything else left or we can close for good.

or many client use outdated cipher suit like MD5 related
