LibreNMS / Monitoring Tools for "weak protocol"

Question

PRTG Monitor per default warns for "weak protocols" and if an SSL check returns "No Secure protocol available"

How can this be done via LibreNMS / Monitoring Tools?

I know you can check for HTTPS via HTTP Check with --sni -S -p 443 -C 30 (if Port 443 and expiration date in 30 days)
