check_ssl_cert – Nagios plugin to check X.509 certificates.

check_ssl_cert is a Nagios plugin to check X.509 certificates. It checks if the server is running and delivers a valid certificate. It also checks if the CA matches a given pattern, and checks the validity.Release Notes v1.14.0: The status now includes performance data in days until expiration (requires Perl with Date::Parse). It is now possible to print additional information in the plugin’s long output (multi-line, Nagios 3 only)
