The -maxWarn & -maxCrit parameters aren't described well in my opinion. They are the number of certs that are expired or will expire. so -maxWarn 1 -maxCrit 2 will give you a warning if 1 cert will expire or a critical if 2 or more certs are expiring.
I'm more interested in setting the number of days ahead of expiration for my warning and critical alerts.
