Heads-up: SSL-Check is bugged

@morbloe I have a rule “WARN if below 45 days and CRIT if below 30 days” and the plugin gets called with -C '45,30'. Yours is being called with -C 5,20 so I guess you mixed up the WARN and CRIT levels?

maybe, but then it should have been critical by now, but it is green.

I switched the values, now it is warning

I second that. I currently don’t have the time to look into the plugin (it’s a binary anyways, IIRC), but I agree it’s buggy. The check should be as simple as

if actual_value < crit_level:
elif actual_value < warn_level:

But maybe the plugin tries to check it the other way round:

if actual_value > warn_level:
elif actual_value > crit_level:

In that case it would return OK for your values. Wrongly.
