Hi Guys, As my first collaboration, following my suggested solution to this problem: According to that manual of check_http plugin[1], we can use that full command to monitoring ssl cert: check_http -H fedoraproject.org -C 20 When the certificate of 'fedoraproject' is valid for more than 20 days, a STATE_OK is returned. When the certificate is still valid, but for less than 20 days, a STATE_WARNING is returned. A STATE_CRITICAL will be returned when the certificate is expired. What you think about this?
