I have been using this for some time at $WORK. I think it is ready for production! |

Add a riemann-tls-check that accept a list of URI of resources to check TLS certificates. For each URI, resolve the IP addresses that provide the service, and for each IP address generate 6 events for: 1. availability: state (reachability + status of all the following metrics); 2. not after: state + metric (number of seconds until the certificate is expired); 3. not before: state + metric (number of seconds since the certificate is valid); 4. identity: state (certificate subject match the URI hostname); 5. trust: state (validity of the certificate trust chain); 6. OCSP satus: state (validity of the OCSP status if applicable). A STARTTLS handshake is automatically done for imap://, ldap:// and smtp://; a protocol specific handshake is done for mysql:// and postgres:// URI.

(icons legend: 🆗/💥 => the metric report a status (ok, warning, critical); 📉 + 📈 => the metric report a metric)

The required API in OpenSSL to check for OCSP Stapling is not currently part of the openssl gem, so this cannot be tested at the moment: ruby/openssl#401
